If you own a BMC Fourstroke 01 29, you already appreciate Swiss precision engineering at its finest. This legendary cross-country full-suspension machine delivers lightweight performance, efficient pedaling, and plush trail feel. But even the best bikes need proper care, especially at critical pivot points. That’s where the Bolt Kit – No 11 comes in as a game-changing spare parts solution.
Designed exclusively for the Fourstroke 01 series, this OEM hardware set keeps your frame tight, your suspension responsive, and your rides worry-free. Whether you’re a weekend warrior, competitive racer, or long-term owner of a 2014-era model, replacing worn fasteners with the right kit prevents costly damage and maintains that factory-fresh feel. In this comprehensive guide, we’ll cover everything you need to know about the Bolt Kit – No 11 — from exact contents to installation tips, benefits, and why it’s worth every penny for serious riders.

What Makes the BMC Fourstroke 01 Special — And Why Bolts Matter
The BMC Fourstroke 01 stands out in the mountain bike world for its carbon frame technology, progressive suspension kinematics, and race-proven geometry. With models from the mid-2010s still crushing trails today, many owners continue to enjoy these bikes years later. However, repeated use on rough terrain puts stress on the suspension pivots, where bolts, caps, and clips secure everything together.
Over time, these components can loosen, corrode, or wear out — leading to creaking noises, suspension play, or even frame damage. Generic hardware simply won’t cut it on a high-end bike like this. The Bolt Kit – No 11 provides factory-spec replacements engineered to the exact tolerances BMC demands. Using original parts ensures perfect fitment, maintains warranty eligibility (where applicable), and preserves the bike’s legendary ride quality.
Compatibility: Is the Bolt Kit – No 11 Right for Your Bike?
This kit is specifically engineered for the BMC Fourstroke 01 29 (particularly 2014 model year and compatible variants). It targets the rear suspension linkage and main pivot areas where the most critical fasteners live.
If you ride an older Fourstroke 01 frame, this is the exact match you’ve been searching for. Later models may use updated kits (like No. 26), so always double-check your frame’s year and part numbers. Owners of the 2014 Fourstroke 01 report excellent results using this set during full frame servicing.
Pro tip: Cross-reference your bike’s serial number or consult a BMC-authorized dealer before ordering to confirm compatibility. The kit’s black finish also blends seamlessly with modern or classic Fourstroke colorways.

What’s Included in the Bolt Kit – No 11
Unlike generic bolt sets, this OEM package contains precisely the hardware your Fourstroke 01 needs. Here’s the complete breakdown:
- 7 long bolts — For main pivot and linkage connections
- 2 short bolts — Ideal for specific mounting points
- 2 caps — Protect threads and provide clean aesthetics
- 3 circlips — Essential for securing bearings in place
- 3 long screws — For additional frame hardware points
Everything arrives ready to install, with the signature black finish that matches BMC’s premium aesthetic. The kit weighs next to nothing yet delivers massive peace of mind. At around $99, you’re getting a complete service set that would cost far more if sourced piece-by-piece from aftermarket suppliers.


These components look professional when laid out — high-grade steel with precise threading and durable finishes. Compare that to cheap alternatives, and you’ll immediately see the quality difference.
Key Benefits of Choosing the Official Bolt Kit – No 11
- Perfect OEM Fit and Performance Every piece matches the original specifications, eliminating play and ensuring smooth suspension action right out of the box.
- Enhanced Durability and Safety High-quality materials resist corrosion and fatigue better than third-party options. This is crucial for preventing pivot failures on aggressive trails.
- Easy Maintenance Replacing all pivot hardware at once during a service saves time and guarantees consistent torque values across the bike.
- Aesthetic Consistency The black finish keeps your BMC looking factory-fresh instead of mismatched with shiny or rusty generic bolts.
- Long-Term Value At under $100, it’s an affordable investment that extends the life of a several-thousand-dollar bike. Many owners report quieter, more efficient pedaling and better suspension feel after installation.
Riders who skip proper pivot hardware often face expensive frame repairs down the line. The Bolt Kit – No 11 is preventive maintenance at its smartest.

Step-by-Step Guide: Installing Your Bolt Kit – No 11
While professional mechanics recommend taking your bike to a certified shop for full suspension service, confident DIY riders can handle this with the right tools. Here’s a high-level overview (always refer to your BMC service manual for exact torque specs):
- Preparation Clean the bike thoroughly. Remove the rear shock if needed and support the frame securely.
- Disassembly Carefully remove old pivots one at a time using the proper tools (Allen keys, circlip pliers). Note the orientation of every piece.
- Inspection Check bearings for wear or contamination — replace if necessary while you have everything apart.
- Installation Insert new long bolts, short bolts, and screws in their respective positions. Install circlips securely and cap off exposed threads.
- Torque and Test Use a calibrated torque wrench to tighten to BMC specifications (typically 8–15 Nm depending on location). Reinstall the shock, spin the cranks, and check for smooth movement with no binding or play.
- Final Check Ride gently at first, then progressively test on trails. Listen for any unusual noises.
Total time for an experienced rider: 1–2 hours. Newer riders should budget a full afternoon and consider professional help for the first service.
Common Fourstroke 01 Issues This Kit Solves
Many 2014-era owners notice creaking from the rear triangle after heavy use. Others report slight suspension sag or inconsistent damping due to loose pivots. The Bolt Kit – No 11 directly addresses these by providing fresh, properly sized hardware. Installing it during a routine bearing service often transforms an aging bike back into a responsive trail weapon.
Where to Buy the Bolt Kit – No 11 and Pricing Tips
The official source is the BMC website (us.bmc-switzerland.com), where it’s listed at $99 with low stock warnings common due to demand. Authorized dealers and specialist online shops like LVR Cycles or eBay listings from reputable sellers also carry it.
Look for part number 215479 to ensure authenticity. Avoid suspiciously cheap copies — they rarely match the tolerances. Free shipping often applies on orders over $150 from the official site, making it convenient to bundle with other maintenance items.
Pro Maintenance Tips for Your BMC Fourstroke
- Service pivots every 50–100 hours of riding or annually.
- Always use thread locker on critical bolts.
- Keep spare circlips on hand — they’re easy to lose during disassembly.
- Combine this kit with a full bearing replacement for maximum results.
- Store your bike indoors to reduce corrosion risk on hardware.
Regular attention to these small details keeps your Fourstroke performing like new for years.
