I’d start with the SAVADECK Carbon Gravel Bike with GRX400 for a clearly specified carbon race setup, then compare it with the SAVADECK SCRB0035 if a claimed 22-speed drivetrain matters more than component clarity. The Tommaso Sterrata takes a different path: its aluminum frame and carbon fork may suit riders who value a stated lifetime frame warranty, but its available product details are less complete.

All three are described as gravel bikes, but the available specifications do not make them equally easy to recommend for racing. The two SAVADECK models share a light listed frame-and-fork weight, hydraulic disc brakes, and 700c wheels with 40 mm tires. The GRX400 version has a more clearly identified drivetrain; the SCRB0035’s speed claims conflict. The Tommaso has less specific component and fit information, and requires professional assembly. My ranking puts verifiable race-relevant details ahead of headline claims, while weighing fit, setup, and warranty information as part of the buying decision.
Complete the kit
Key Takeaways
- Best-supported race specification: The SAVADECK GRX400 lists a 20-speed Shimano drivetrain and RX400 hydraulic brakes, making its component package the clearest of the three.
- Do not buy on speed count alone: The SCRB0035 is advertised with 22 speeds, but its drivetrain description is inconsistent, so confirm the exact components before ordering.
- Fit is a major unknown: Both SAVADECK listings provide only one size, with the SCRB0035 specifying a recommended rider-height range of 5′7″–5′11″.
- Race tires need a terrain match: The SAVADECK bikes’ 700x40c tires aim to balance paved speed and gravel grip, but tire choice should reflect your course and preferred handling.
- Assembly separates the alternatives: The Tommaso requires professional assembly; the SCRB0035 arrives 90% pre-assembled with tools, while the GRX400 listing includes a tool kit.

More Details on Our Top Picks
SAVADECK Carbon Gravel Bike with Shimano GRX400
This is my leading pick because it combines the most clearly defined component package in this group with a T800 carbon frame and fork, a listed weight of 10.4 kg (22.92 lb), and 700x40c tires. For a gravel racer, the appeal is not simply the carbon construction: the 20-speed Shimano GRX400 drivetrain and Shimano RX400 hydraulic brakes are identified by model, giving the buyer a more useful basis for checking the build than the SCRB0035’s conflicting drivetrain claims or the Tommaso’s generic Shimano description.
The 40 mm tires point toward a versatile race setup for courses that mix paved connectors with rougher gravel. They may offer more comfort and grip than narrower road-focused tires, though the listing does not specify tire casing, tread, or frame clearance for fitting wider options. The bike is rigid, as all three listings indicate or imply; there is no built-in suspension to smooth repeated impacts. That keeps the setup straightforward but makes tire pressure, surface choice, and fit more consequential over long, rough events.
Its main obstacle is fit confidence. Only a 51 cm frame size is listed, so I would not assume it works for a particular rider based on the model name alone. Check the seller’s geometry chart and sizing guidance before purchase, especially if you plan to race in a low, sustained position. The Tommaso may be worth investigating for someone who prefers an aluminum frame and a stated lifetime frame warranty, while the SCRB0035 lists a rider-height band; neither alternative, however, supplies a more complete fit picture overall. I’d choose this SAVADECK when its size matches and a clearly named Shimano gravel drivetrain matters more than unverified claims about extra gears.
Pros:- T800 carbon frame and fork with a listed 10.4 kg weight
- Named 20-speed Shimano GRX400 drivetrain
- Shimano RX400 hydraulic disc brakes
- 700x40c tires suit mixed paved and unpaved routes
Cons:- Only a 51 cm frame size is listed
- Rigid design has no built-in impact absorption
- The listing does not provide geometry or tire-clearance details
Best for: Riders seeking a carbon gravel race bike with a specifically identified Shimano GRX400 drivetrain and RX400 hydraulic brakes, provided the listed 51 cm size suits their fit.
Not ideal for: Racers who need a different confirmed frame size, want suspension for rough courses, or require detailed geometry and tire-clearance information before choosing a bike.
- Frame and fork:T800 R21 carbon fiber
- Listed weight:10.4 kg (22.92 lb)
- Drivetrain:Shimano GRX400, 20-speed
- Brakes:Shimano RX400 hydraulic disc
- Crankset:Shimano RX600
- Tires:700x40c
- Wheels:700c, aluminum
- Frame size:51 cm listed
- Warranty:2-year limited
Our verdict“I’d put the GRX400 first for racers who can confirm the 51 cm fit and want the most clearly specified drivetrain in this lineup.”
SAVADECK SCRB0035 Carbon Gravel Bike with Shimano 22-Speed Drivetrain
The SCRB0035 looks like the more gear-focused SAVADECK on paper: it claims a 22-speed Shimano drivetrain while retaining a T800 carbon frame and fork, hydraulic disc brakes, and 700x40c tires. The listing also says the frame and fork weigh 10.4 kg, though it is unclear whether that figure refers to the complete bike, so I would not use it as a direct complete-bike weight comparison with the GRX400 model. Its combination may suit a rider who wants carbon construction and a broad advertised gear count, but the specification needs checking before that claim can guide a race-bike purchase.
The concern is that the supplied description identifies Shimano U6000 components, while the title and speed claim do not provide a consistent, detailed drivetrain breakdown. A gear count alone does not tell me cassette range, chainring sizes, shift quality, or whether the setup suits a steep course. By comparison, the GRX400 bike names its drivetrain and crankset more clearly, which makes it the safer recommendation for a buyer prioritizing known components. I would ask the seller to confirm the exact shifters, derailleurs, crank, cassette, and chain before treating the SCRB0035 as a 22-speed race option.
Its 700x40c tires and hydraulic brakes make the intended mixed-terrain use easy to understand, and internal cable routing gives the frame a tidier appearance. The bike is stated to arrive 90% pre-assembled with tools, a practical advantage over the Tommaso’s explicit professional-assembly requirement. Still, near-complete assembly does not mean a race-ready setup: the buyer may need to check the final assembly and adjustment. Fit also needs attention. The listing gives a recommended rider height of 5′7″–5′11″ but only one frame size, so riders near either end of that range should seek geometry and fit confirmation. I’d choose it over the GRX400 only if the drivetrain details are verified and its size fits better.
Pros:- T800 carbon fiber frame and fork
- Hydraulic disc brakes and 700x40c tires
- Internal cable routing
- Arrives 90% pre-assembled with a tool kit
Cons:- Drivetrain speed and component claims are inconsistent
- Only one frame size is specified despite a rider-height range
- The 10.4 kg figure is labeled as frame-and-fork weight, not clearly complete-bike weight
Best for: Riders interested in a carbon gravel bike advertised with a 22-speed drivetrain who are prepared to verify the exact Shimano components and confirm the single-size fit.
Not ideal for: Buyers who need a fully consistent parts list, several confirmed frame sizes, or a race bike they can evaluate without contacting the seller for clarification.
- Frame and fork:T800 carbon fiber
- Listed weight:10.4 kg for frame and fork; complete-bike weight not specified
- Drivetrain:Shimano U6000 components; listing also claims 22 speeds
- Brakes:Hydraulic disc
- Tires:700x40c
- Wheel material:Aluminum
- Suspension:Rigid
- Fit information:One size specified; recommended rider height 5′7″–5′11″
- Assembly and warranty:90% pre-assembled; 2-year warranty
Our verdict“I’d shortlist the SCRB0035 for its advertised gear count and mostly assembled delivery, but only after the seller confirms the drivetrain and fit details.”
Tommaso Sterrata Aluminum Gravel Bike with Carbon Fork and Shimano Drivetrain
The Tommaso Sterrata is the outlier here: instead of a full carbon frame like both SAVADECK options, it pairs an aluminum frame with a carbon fork. That construction may interest a rider who prefers an aluminum frame and wants a carbon fork, but the supplied details are too sparse to establish how the bike compares on race weight, gearing, or terrain range. Its stated lifetime frame warranty is a distinct point of differentiation, though warranty coverage and exclusions should be checked directly with the manufacturer.
For gravel racing, the missing specification detail is a real drawback. “Shimano components” does not identify the drivetrain level, number of gears, crank, cassette, or brakes. The listing also contains conflicting model and component details, so I would not assume the bike has a particular setup based on the broad description. The GRX400 SAVADECK is easier to assess because it names the drivetrain and hydraulic brakes; the SCRB0035 at least states tire size and brake type, even though its drivetrain claims need verification. Here, important race questions remain unanswered, including tire size, wheel material, weight, frame sizing, and brake specification.
Assembly is another factor: the Sterrata requires professional assembly, unlike the SCRB0035, which arrives mostly assembled with tools. That requirement may be welcome to riders who want a mechanic to check setup, but it adds a step and makes the bike less convenient for someone seeking a quick start. I would consider this model only after obtaining a current, itemized specification sheet and confirming its fit and race suitability. It ranks third because the frame-and-fork concept and warranty are appealing, yet the available information does not support a confident comparison of its performance with the better-specified SAVADECK bikes.
Pros:- Aluminum frame paired with a carbon fork
- Shimano components are specified, even though the exact parts are not
- Lifetime frame warranty is stated
- May appeal to riders who prefer a non-carbon frame
Cons:- Conflicting model and component details make the build uncertain
- Professional assembly is required
- Tire size, weight, brake details, and frame sizing are not supplied
Best for: Riders who specifically want an aluminum frame with a carbon fork, value a stated lifetime frame warranty, and are willing to confirm the current build and pay for professional assembly.
Not ideal for: Race-focused buyers who need verified drivetrain, brake, tire, weight, and sizing details before choosing, or who want a bike ready to set up without a mechanic.
- Frame:Aluminum
- Fork:Carbon
- Drivetrain:Shimano components; exact model and gearing not specified
- Brakes:Not specified
- Tire size:Not specified
- Frame size:Not specified
- Assembly:Professional assembly required
- Frame warranty:Lifetime, as stated in product details
Our verdict“I’d consider the Sterrata only after confirming its exact build and fit; its warranty and frame material cannot make up for missing race-critical specifications on their own.”
How We Picked
I ranked these bikes around the demands of gravel racing: a useful balance of speed, control, reliable shifting and braking, and a fit that a rider can verify before committing. I gave more weight to specifications that identify actual components than to broad claims such as “performance” or a drivetrain speed count without a consistent parts list. That distinction matters when a bike will be pushed over rough surfaces and shifting or braking problems can interrupt a race.
I also compared the details riders need to evaluate fit and readiness. Tire width, frame material, stated weight, assembly requirements, warranty information, and the completeness of the sizing details all affect whether a bike is a practical race choice. A carbon frame can reduce listed weight, but it does not by itself establish handling quality, durability, or fit. Similarly, hydraulic disc brakes are a relevant feature for variable gravel conditions, but the listings do not provide rotor sizes or other details that would support claims about braking performance.
The SAVADECK GRX400 ranks first because it has the most coherent drivetrain and brake specification alongside a carbon frame and fork and 40 mm tires. The SCRB0035 ranks second: its 22-speed claim could appeal to racers seeking a broad gear range, yet inconsistent drivetrain wording and a single stated size weaken confidence. The Tommaso Sterrata ranks third, not because aluminum is automatically unsuitable for racing, but because its listing gives little detail on gearing, brakes, tire clearance, or fit, and calls for professional assembly. I treat missing information as a buying limitation, not proof that a component is poor. Specifications are based on the supplied product details; I do not infer unlisted race features or claim firsthand testing.

Factors to Consider When Choosing Best Gravel Race Bikes
I’d choose a gravel race bike by matching its verified specification and fit to the course, rather than treating carbon construction or a high gear count as proof that it will be faster. The differences among these three listings make that distinction especially useful: one has a clearly named GRX400 build, another has a disputed 22-speed claim, and the Tommaso leaves several core details unspecified.
Start with fit, not the material label
A bike that is difficult to fit is a poor race choice, regardless of its frame material. The GRX400 SAVADECK lists only a 51 cm size. The SCRB0035 lists one size and a recommended rider-height range of 5′7″–5′11″. Those details are a starting point, not a substitute for a geometry chart: reach, stack, seat-tube length, and your preferred position can determine whether a bike feels suitable over several hours. The Tommaso listing provides no frame sizing. Before buying any of these, I would ask for the current geometry and size options, then compare them with a bike position that already works for you.
Fit affects comfort and control, but also your ability to hold a stable position while changing surfaces. A size that is too long or too short can make it harder to maintain a balanced grip and steer confidently on loose corners. If the seller cannot confirm the size or geometry, I would treat that as a meaningful risk rather than rely on a general height recommendation.
Check the drivetrain parts, not just the speed count
More listed speeds do not automatically mean a better race drivetrain. What matters is the actual gear range and whether the steps between gears suit your course, cadence, and fitness. The GRX400 SAVADECK gives a clearer baseline by naming a 20-speed Shimano GRX400 drivetrain and RX600 crankset. The SCRB0035 advertises 22 speeds but also uses inconsistent drivetrain descriptions. I would ask for the shifter, front and rear derailleur, cassette, and chainring details before comparing it as a 22-speed alternative. The Tommaso’s broad Shimano label does not provide enough information to judge its gearing.
For a course with long climbs, a low climbing gear may matter more than the total number of combinations. A fast, flat course may place different demands on the top end and gear spacing. Without chainring and cassette sizes, the listings do not let me make a reliable course-specific gear comparison. Confirming those details is more useful than choosing by the number in a title.
Match tire width and tread to the course
Both SAVADECK listings specify 700x40c tires, a width that can suit mixed paved and unpaved routes. Compared with a narrow road tire, a 40 mm tire can provide more room for grip and comfort on rougher gravel; compared with a much wider setup, it may better suit smoother courses and fast connectors. Tire casing, tread pattern, pressure, and rim compatibility also influence speed and control, but those details are not included here. The Tommaso listing does not give a tire size, which makes it harder to judge its race terrain range.
Before picking a bike, think about the surfaces you actually race. Hard-packed gravel and long paved links call for a different tire choice than loose, rocky tracks. Ask whether the frame and fork have room for your preferred tire, particularly if you may want a wider setup later. The provided SAVADECK details do not list maximum clearance, so I would confirm it rather than assume the stock tire size is the limit—or assume there is space to go larger.
Weigh frame construction against complete-bike information
The two SAVADECK options have T800 carbon frames and forks, while the Tommaso combines an aluminum frame with a carbon fork. A carbon frame can help reduce weight, but the listings do not provide enough information to compare ride feel, durability, or stiffness. The GRX400 bike lists 10.4 kg as its weight. The SCRB0035 labels the same figure as the weight of its frame and fork, so I would not compare it as a complete-bike weight. The Tommaso gives no weight at all.
For racing, the complete build matters: wheels, tires, brakes, and drivetrain all contribute to how the bike performs and how it can be maintained. The SAVADECK models list aluminum wheels, but no wheel model or other detailed build information. I would view frame material as one part of the decision, not a shortcut to ranking a bike. The Tommaso’s stated lifetime frame warranty may be relevant to a buyer, but it does not answer questions about component service or warranty exclusions.
Treat assembly and support as part of race readiness
The SCRB0035 is described as 90% pre-assembled and includes tools; the GRX400 listing also includes a tool kit. The Tommaso requires professional assembly. These descriptions affect convenience, but none should be read as a guarantee that the bike is fully adjusted for racing out of the box. A careful final check of brake function, shifting, fasteners, tire pressure, and fit is sensible before a hard ride. If you are not comfortable with assembly or adjustment, plan for qualified help even when a listing says the bike arrives mostly assembled.
Warranty terms deserve the same careful reading. The GRX400 listing states a 2-year limited warranty, the SCRB0035 states a 2-year warranty, and the Tommaso lists a lifetime frame warranty. Coverage can differ by component and may include conditions on assembly, registration, or use. I would verify the written terms with the seller or manufacturer and keep the documentation. A longer frame warranty is a useful distinction, but it does not resolve uncertainty about the rest of the bike’s specification.
Use the ranking as a shortlist, then verify the listing
My ranking favors the GRX400 SAVADECK because its drivetrain and brakes are the most clearly identified, not because the supplied details prove it will be the fastest. The SCRB0035 may suit someone drawn to its claimed 22-speed setup and mostly assembled delivery, but I would wait for a consistent parts list. The Tommaso Sterrata is the aluminum-frame alternative with a stated lifetime frame warranty, yet it needs the most follow-up on fit, brakes, tires, and gearing.
Before ordering, confirm that the exact model and component build match the current listing, ask for frame geometry and sizing, and check the return and warranty terms. For racing, a verified fit and build are more useful than a headline claim. If a seller cannot answer basic questions about the drivetrain, brakes, and frame size, I would keep looking rather than assume the missing information will not matter.
Frequently Asked Questions
Which of these three is the strongest gravel race-bike pick?
I rank the SAVADECK Carbon Gravel Bike with Shimano GRX400 first because the listing identifies a 20-speed GRX400 drivetrain, RX400 hydraulic brakes, a carbon frame and fork, and 700x40c tires. That gives me a clearer basis for judging the build than the SCRB0035’s inconsistent drivetrain claims or the Tommaso’s sparse component details. Its one listed frame size is a substantial caveat, so I would confirm fit before choosing it.
Is the SCRB0035’s 22-speed drivetrain better than the GRX400 setup?
Not on the supplied information alone. The SCRB0035 advertises 22 speeds but its drivetrain descriptions are inconsistent, and the listing does not provide a complete parts breakdown. A speed count does not show the cassette range, chainring sizes, or gear spacing. The GRX400 model is easier to evaluate because it names the drivetrain and crankset. I would ask the SCRB0035 seller to confirm its shifters, derailleurs, cassette, crank, and chain before making a direct comparison.
Are 700x40c tires suitable for gravel racing?
They can be a sensible choice for events that mix paved sections with gravel, since 40 mm tires offer a useful middle ground between a narrow road setup and a much wider tire. Suitability depends on the course surface, tread, casing, pressure, rim compatibility, and rider preference. The two SAVADECK listings specify 700x40c tires but do not state tread or maximum tire clearance. I would confirm the setup matches your event and ask whether the frame can take a different width if you may want to change tires.
What should I know about sizing these bikes?
The GRX400 SAVADECK lists only a 51 cm frame. The SCRB0035 lists one size and recommends it for riders 5′7″–5′11″, while the Tommaso listing does not give a size. Those details are not enough to confirm fit for every rider. I would request each bike’s geometry chart and compare reach and stack with a bike that fits you well, then confirm the seller’s size and return policies before ordering.
Is the Tommaso Sterrata worth considering for racing?
It may suit a rider who wants an aluminum frame with a carbon fork and values the stated lifetime frame warranty, but I would not buy it for racing without further information. The supplied details do not specify tire size, weight, brakes, gearing, or frame size, and they mention conflicting model and component details. Professional assembly is also required. I would request a current, itemized build sheet and confirm fit before comparing it with the more fully specified SAVADECK bikes.
Conclusion
For most buyers in this comparison, I’d choose the SAVADECK GRX400 if the listed 51 cm frame fits and the current build matches the stated Shimano components. Its clearest advantage is specification confidence, not a claim that carbon automatically makes it faster. If you prefer the advertised 22-speed setup and can verify every drivetrain part, the SCRB0035 is the alternative to investigate; its limited sizing information should be part of that decision. If an aluminum frame, carbon fork, and stated lifetime frame warranty matter most, the Tommaso Sterrata is worth a closer look only after confirming its missing race-critical details and arranging professional assembly.
My practical recommendation is to check geometry, exact parts, tire clearance, and written warranty terms before buying any of the three. For a gravel race bike, a well-fitting and accurately specified build is a stronger starting point than a gear-count claim or frame-material label on its own.
