Choosing a 230 × 65 mm coil shock starts with fit, but the right choice also depends on how much tuning you need and how much product information you can verify. My leading picks are the BUCKLOS GRAVO for a straightforward coil setup with compression and rebound controls, the JKY RCT-2 for riders who want coil-air adjustment, and the XFUSION H3C RCP for a lighter shock body with a three-position platform.

Those options serve different priorities. BUCKLOS lists a firm 550 lb spring, while XFUSION specifies a 450 lb spring, so neither rate should be treated as universally suitable. JKY adds an air chamber and four adjustment types, but its shock pump is not included. The Öhlins TTX22M.2 offers the widest damping adjustment described here, though it sits awkwardly in a budget-focused shortlist and requires a separate spring. The Marzocchi Bomber CR is difficult to compare because the supplied listing gives very little technical detail. I rank these by useful fit-specific information, adjustability, and how clearly each helps a buyer make a decision.

Key Takeaways
- Confirm your frame requires 230 mm eye-to-eye length and 65 mm stroke before comparing any of these shocks.
- BUCKLOS lists a 550 lb spring and adjustable compression and rebound; the fixed spring rate may not suit every rider.
- JKY combines a 550 lb coil with adjustable air pressure, but its high-pressure shock pump is a separate requirement.
- XFUSION lists a 450 lb spring, a three-position platform, low-speed compression and rebound adjustment.
- Öhlins provides extensive damping controls but sells the spring separately; the Marzocchi listing lacks enough detail for a confident spec-by-spec comparison.

More Details on Our Top Picks
BUCKLOS MTB Coil Spring Rear Shock 230L × 65mm
The BUCKLOS GRAVO is the clearest straightforward coil option in this group: its listing specifies 230 mm eye-to-eye, 65 mm stroke, and a 550 lb spring, along with adjustable compression and rebound. That makes it easier to assess than the Marzocchi listing, which does not provide comparable setup details, and simpler than JKY’s coil-air layout. The adjustment controls offer a way to tune how the shock resists compression and returns after an impact, without adding an air-pressure adjustment step.
The main qualification is the fixed spring rate described in the listing. A 550 lb spring may be too firm or too soft depending on rider weight and the frame’s leverage curve, so I would check the bike maker’s spring guidance before choosing it. Compared with XFUSION’s listed 450 lb spring, BUCKLOS targets a different support level; those figures are not a quality ranking. Its lack of lockout also matters for riders who want a firm climbing mode. The product description claims rugged use and corrosion resistance, but the supplied information offers limited broader validation, so I would treat those claims as specifications rather than proven long-term performance.
Pros:- Lists the exact 230 × 65 mm size.
- 550 lb coil spring is specified.
- Compression and rebound are adjustable.
- Aluminum alloy body is described for off-road use.
Cons:- No lockout feature is listed.
- The 550 lb spring may not suit every rider or frame.
- The supplied listing provides limited validation beyond its claims.
Best for: Riders whose frame takes a 230 × 65 mm shock and whose setup calls for a 550 lb coil with compression and rebound adjustment.
Not ideal for: Riders who need a lockout, need another spring rate, or want a shock with extensive independent performance evidence.
- Brand:BUCKLOS
- Model:GRAVO
- Type:Coil spring rear shock
- Size:230 mm eye-to-eye × 65 mm stroke
- Spring rate:550 lb
- Adjustments:Compression and rebound
- Material:Aluminum alloy
- Application:Downhill mountain biking and e-bikes
Our verdict“I’d shortlist the BUCKLOS when its 550 lb spring matches the bike setup and a direct coil with two damping adjustments is the goal.”
Mountain Bike Rear Shock Absorber, 550LBS Coil-Air, 230 × 65 mm
The JKY RCT-2 earns its place for offering more adjustment paths than the BUCKLOS: in addition to rebound, compression and preload, it has an air chamber specified for 200–300 PSI. That combination could suit a rider who wants to fine-tune support beyond a coil collar and damping controls. Its 550 lb spring rate matches BUCKLOS on paper, but the added air adjustment changes the setup process and makes this a distinct option rather than a simple substitute.
That flexibility comes with extra requirements. The listing says the high-pressure shock pump is not included, and the stated 24 mm bushings must match the frame hardware. It also gives six size options, so buyers should confirm that the selected variant is actually 230 × 65 mm, rather than relying on a broad product title. Against the Öhlins, JKY describes air-pressure tuning but not the same high- and low-speed compression controls. I would view it as the more configurable budget-style choice, while recognizing that the listing itself does not establish how well its adjustments perform over time.
Pros:- Lists rebound, compression, preload and air-pressure adjustment.
- 550 lb/in coil spring is specified.
- 230 × 65 mm is one of the stated size options.
- Aluminum alloy body is specified.
Cons:- High-pressure shock pump is not included.
- Included 24 mm bushings may not fit every frame.
- Multiple variants make careful size selection necessary.
Best for: Riders who specifically want a 230 × 65 mm coil-air shock and already have, or plan to buy, a high-pressure shock pump.
Not ideal for: Riders seeking a simple coil-only replacement, those who cannot verify 24 mm mounting widths, or anyone unwilling to manage air pressure.
- Brand:JKY
- Model:RCT-2
- Type:Coil-air rear shock
- Size option:230 mm eye-to-eye × 65 mm travel
- Spring rate:550 lb/in
- Air pressure:200–300 PSI stated range
- Adjustments:Rebound, compression, preload and air pressure
- Bushings:24 mm upper and lower; verify frame fit
- Pump:High-pressure shock pump not included
Our verdict“I’d choose the JKY for its coil-air tuning range only after confirming the selected size, mounting widths and pump requirement.”
XFUSION H3C RCP Coil Rear Shock, 230 × 65 mm
XFUSION takes a different approach from BUCKLOS and JKY: the H3C RCP lists a three-position platform alongside low-speed compression and rebound adjustment. That gives the buyer a named platform control in addition to damping setup, which may appeal to someone who switches between climbing and descending. Its stated 450 lb spring is lighter than the 550 lb springs listed for BUCKLOS and JKY, making spring matching especially important rather than automatically better or worse.
The shock body is listed at 318 g without the spring, a useful comparison point for a buyer tracking component weight, though the spring adds to the installed total. XFUSION also identifies IGUS DU bushings and a metric mount. Compared with the Öhlins, the supplied description gives fewer damping increments and no high-speed compression control; compared with BUCKLOS, it offers the platform setting but a different spring rate. Its 450 lb spring may not be the right match, and the data supplied here says little about spring availability or the exact platform positions. I would confirm those details with the seller and frame maker before ordering.
Pros:- Three-position platform is specified.
- Low-speed compression and rebound are adjustable.
- IGUS DU bushings are listed.
- Shock body weight is listed as 318 g without spring.
Cons:- 450 lb spring may not fit the rider and frame setup.
- Weight excludes the spring.
- The supplied details do not specify adjustment increments or spring options.
Best for: Riders who want a metric 230 × 65 mm coil shock with a three-position platform and whose setup is compatible with a 450 lb spring.
Not ideal for: Riders who need a heavier spring, detailed high-speed damping controls, or a fully specified spring and adjustment package before buying.
- Brand:XFUSION
- Model:H3C RCP
- Type:Coil rear shock
- Size:230 × 65 mm
- Spring rate:450 lb
- Mount:Metric
- Adjustments:Three-position platform, low-speed compression and rebound
- Bushings:IGUS DU
- Weight:318 g without spring
Our verdict“I’d favor the XFUSION when the 450 lb spring suits the bike and a platform control matters more than a broad range of damping adjustments.”
Öhlins TTX22M.2 Coil Shock, 230 mm
The Öhlins TTX22M.2 is the most explicitly adjustable shock in this lineup. Its listing describes high-speed compression with three settings, low-speed compression with 16 clicks, and rebound with seven clicks, plus stroke adjustment. The bump rubber and cup are presented as an auxiliary spring system intended to control the return after a heavy compression. Compared with the BUCKLOS, it gives a much more detailed damping setup; compared with JKY, its documented tuning centers on damping rather than air pressure.
Its rank is lower for this budget-oriented search because the listing states that the coil spring is sold separately, and the extensive controls may be more than a rider seeking a basic replacement needs. The title includes several stroke options, so the selected version must be confirmed as 230 × 65 mm. This shock is described for gravity riding and less progressive bikes, but frame compatibility and spring selection still need to be checked. Buyers should also account for the required separate spring when comparing the complete setup with options that specify a spring in the listing.
Pros:- High-speed compression, low-speed compression and rebound controls are described.
- Stroke adjustment is specified.
- Bump rubber and cup are designed to add end-stroke support.
- 230 × 65 mm is among the listed size options.
Cons:- Coil spring is sold separately.
- Several stroke options require careful variant selection.
- Its detailed controls may be unnecessary for a simple replacement.
Best for: Gravity riders who need fine compression and rebound tuning, can source a compatible spring separately, and have a frame designed for this shock.
Not ideal for: Budget-minded buyers seeking a complete ready-to-fit spring-and-shock package or riders who do not need multiple damping controls.
- Brand:Öhlins
- Model:TTX22M.2
- Type:Coil rear shock; spring sold separately
- Eye-to-eye length:230 mm
- Available stroke:Includes 65 mm; other options also listed
- High-speed compression:3 settings
- Low-speed compression:16 clicks
- Rebound:7 clicks
- Use:Gravity, enduro and downhill riding
Our verdict“I’d pick the TTX22M.2 for damping adjustability when the separate spring and more involved setup suit the buyer’s needs.”
Marzocchi Bomber CR Metric 230 × 65 mm
The Marzocchi Bomber CR is listed as a metric 230 × 65 mm rear shock, which gives a buyer the basic size needed to start a fit check. Beyond that, the supplied product information is sparse: it does not identify spring rate, adjustment controls, weight, or included spring. That makes it hard to compare directly with BUCKLOS, XFUSION or Öhlins, all of which have more of their setup details described. I place it fifth because the listing leaves more buying questions unanswered, not because the available information proves the shock performs poorly.
For someone replacing an existing Bomber CR or already familiar with the exact version, the named model and metric dimensions may be enough to investigate compatibility further. A buyer choosing a first coil shock has less to work with here than with the JKY, whose adjustment and bushing details are stated, or the BUCKLOS, which specifies a spring rate and damping controls. Before purchase, confirm the spring, hardware, damping configuration and whether the selected product is the exact 230 × 65 mm version. Without those answers, the size alone is not enough to establish that it suits the bike.
Pros:- Listed as a Marzocchi Bomber CR.
- 230 × 65 mm metric size is identified.
- Rear shock application is stated.
Cons:- Spring rate is not provided in the supplied listing.
- Damping adjustments are not described.
- Included spring and mounting hardware are unclear.
Best for: A rider replacing a known Marzocchi Bomber CR setup who can verify spring, hardware and damping details against the existing shock.
Not ideal for: First-time coil-shock buyers who need a clearly documented spring rate, included components and adjustment range.
- Brand:Marzocchi
- Model:Bomber CR
- Type:Metric coil rear shock, per product title
- Size:230 × 65 mm
- Year in title:2024
- Spring rate:Not provided in supplied product information
- Adjustments:Not provided in supplied product information
- Included components:Not specified
Our verdict“I’d consider the Bomber CR only after confirming the exact spring and setup details, since the supplied listing cannot support a full comparison.”
How We Picked
I ranked these choices around the specific needs of a buyer seeking a 230 × 65 mm coil shock. First, I looked for a clearly stated eye-to-eye length and stroke, because a shock that does not match the frame’s required dimensions is not a useful bargain. I then compared the listed spring support and damping controls: those determine whether a buyer gets a simple coil replacement or room to tune the ride.
I also weighed practical constraints that can change the ownership experience. The JKY needs a high-pressure shock pump for its air chamber, while the Öhlins spring is sold separately. BUCKLOS and XFUSION state spring rates, but the right rate depends on rider weight, frame leverage and setup; a listed number alone does not prove fit. Finally, I considered how much useful information the listing provides. That puts products with identifiable specifications ahead of the Marzocchi listing, whose description does not establish its spring rate or damping controls. The ranking reflects documented fit and features, not independent durability testing or a claim that one spring rate fits everyone.

Factors to Consider When Choosing Budget Coil Shock 230×65
For a 230 × 65 mm coil shock, I would settle fit and spring choice before comparing adjustment features. A matching headline size is a starting point; mounting width, hardware, spring clearance and frame requirements also affect whether a shock belongs on the bike.
Verify eye-to-eye length, stroke and mounting hardware
230 mm eye-to-eye is the distance between the shock mounting points when extended, while 65 mm is the shock’s travel. Check both against the frame manufacturer’s specification. Also measure upper and lower mounting widths and bolt diameters; the JKY listing’s 24 mm bushings, for example, may not match every frame. Confirm spring and reservoir clearance through the full travel. A shock that fits the nominal size but fouls the frame or changes the bike’s intended geometry is the wrong choice.
Choose spring rate for the rider and frame
The listed rates in this group range from 450 lb on XFUSION to 550 lb on BUCKLOS and JKY. Spring rate is not a simple measure of quality, and the same number can feel different across frames because leverage curves vary. Use the bike maker’s recommendation or a suspension specialist’s guidance, then account for rider weight and riding equipment. Check whether the spring is included: Öhlins explicitly sells it separately, while the Marzocchi details provided here do not say what is included.
Match the adjustment style to how you ride
BUCKLOS lists compression and rebound adjustment for a fairly direct coil setup. XFUSION adds a three-position platform and identifies low-speed compression and rebound. JKY adds preload and an air chamber, offering more ways to tune support but requiring a high-pressure shock pump. Öhlins gives the most detailed damping controls in the supplied descriptions, including high-speed compression settings. I would favor the controls that address a real setup need; extra knobs only help when their function and adjustment guidance are clear.
Compare the complete setup, not just the shock body
A listing may omit parts needed to install or tune the shock. The Öhlins spring is separate, and JKY’s pump is not included. XFUSION’s listed 318 g excludes its spring. For any option, verify spring compatibility, mounting hardware, installation requirements and the selected size variant. The Marzocchi listing needs the most follow-up because its supplied details do not identify spring rate or adjustment range. These checks give a more useful comparison than a bare product title.
Treat budget claims as a fit and information question
Because this comparison is focused on budget choices and does not provide reliable price data, I judge value by how much useful setup information and functionality the listing establishes. BUCKLOS is a clear coil-and-damping package on paper; JKY trades simplicity for a coil-air system; XFUSION distinguishes itself with a platform control; Öhlins offers extensive tuning with a separate spring; Marzocchi needs more verification. I would not pick a shock by brand or feature count alone when the required spring or mount does not match.
Frequently Asked Questions
How do I confirm that a 230 × 65 mm shock fits my bike?
Check the frame manufacturer’s specification for both eye-to-eye length and shock travel, then measure mounting widths and bolt diameters. Confirm clearance for the spring and shock body across the suspension’s travel. A 230 × 65 mm label does not confirm that the bushings, hardware or frame clearance match your bike.
Which spring rate should I choose?
Use the frame maker’s spring guidance as a starting point and account for rider weight with riding equipment, frame leverage and intended use. The 450 lb XFUSION and 550 lb BUCKLOS and JKY options are not interchangeable recommendations for every rider. If the correct rate is uncertain, ask a suspension specialist before ordering.
What is different about the JKY coil-air shock?
The JKY combines a 550 lb/in coil with an adjustable air chamber and lists rebound, compression, preload and air pressure as adjustment points. That offers more ways to tune it than the BUCKLOS listing describes, but it also adds setup work. The required high-pressure shock pump is not included, and its 24 mm bushings need to match the frame.
Does the Öhlins TTX22M.2 include a coil spring?
No. The supplied product description says the coil spring is sold separately. Buyers should confirm the required spring rate and compatibility for their frame, and select the 230 × 65 mm version because the listing also names other stroke options. Include the spring requirement when comparing it with packages that specify a spring.
Which listing gives me the least uncertainty before buying?
BUCKLOS states its 230 × 65 mm size, 550 lb spring and compression and rebound adjustments, while XFUSION provides a 450 lb spring rate and platform details. JKY lists more setup information but requires a pump and careful bushing checks. The supplied Marzocchi details are the sparsest, so I would seek confirmation of its spring, adjustments and included hardware before choosing it.
Conclusion
For a clearly specified coil setup, I’d start with the BUCKLOS GRAVO, provided its 550 lb spring suits the frame and rider. Choose the JKY RCT-2 if coil-air tuning is the priority and you can handle the pump and fit checks. The XFUSION H3C RCP makes more sense for a buyer whose setup matches its 450 lb spring and who wants a platform control. For gravity riders seeking fine damping adjustments, the Öhlins TTX22M.2 has the richest listed controls, with a separate spring to source. I’d shortlist the Marzocchi Bomber CR only when replacing a known setup or after confirming its missing spring and adjustment details. Across all five, fit and spring compatibility come before brand or feature count.
