Bolt Kit – No 19: The Essential Spare Part Guide for BMC Speedfox Owners – Keep Your Suspension Performing Perfectly

If you ride a BMC Speedfox trail bike, you already appreciate the precision engineering that makes these Swiss-made machines feel alive on the trails. But even the best full-suspension setups need occasional care, especially around the rear linkage pivots. That’s where the Bolt Kit – No 19 comes in as a game-changing official spare part.

Whether you’re dealing with creaking noises, slight play in the suspension, or simply planning preventive maintenance after hundreds of kilometers, this kit restores factory-fresh performance without compromise. In this comprehensive guide, we’ll cover everything you need to know about the Bolt Kit – No 19 – from its exact purpose and compatibility to installation tips, benefits, and where to buy it. Let’s dive in so you can keep your Speedfox riding like new for years to come.

What Is the Bolt Kit – No 19 and Why Does Your BMC Speedfox Need It?

The Bolt Kit – No 19 (also listed as Bolt Kit – No 19 Black) is an official BMC spare parts package engineered specifically for the rear suspension linkage on select Speedfox models. Unlike generic hardware store bolts, this kit contains precision-machined, black-anodized long bolts plus all the necessary washers, spacers, and clips required for a complete pivot refresh.

BMC designs these numbered bolt kits to match the exact tolerances of their dual-link suspension systems. Over time, pivot bolts can wear from dirt ingress, repeated loading, or even normal trail abuse. Replacing them with the correct OEM kit prevents bigger issues like bearing damage or frame stress. The black finish not only looks sleek against the frame but also offers excellent corrosion resistance – perfect for riders who tackle wet, muddy, or coastal trails.

Compatible BMC Models: Does Your Speedfox Use the Bolt Kit – No 19?

This kit is purpose-built for the following BMC Speedfox models (primarily 2014–2017 era full-suspension 29ers and Trailcrew variants with 130mm travel):

• Speedfox SF02 29 (carbon front triangle + alloy rear)
• Speedfox SF03 29 (full alloy frame)
• Speedfox SF02TC
• Speedfox SF03TC

These bikes popularized playful yet efficient trail riding with their APS (Advanced Pivot System) suspension. If your frame has a model code starting with SF02 or SF03 and 29-inch wheels, the Bolt Kit – No 19 is almost certainly the correct replacement hardware for the main pivot points.

Always double-check your bike’s serial number or frame sticker against BMC’s official parts lookup before ordering – but for most owners of these classic trail rippers, this is the go-to kit.

What’s Actually Included in the Bolt Kit – No 19?

According to BMC’s specifications, the kit centers around six long black bolts plus the complete supporting hardware (bushings, washers, circlips, and spacers). The full assortment ensures you can refresh every critical pivot without hunting for individual pieces.

Typical contents (based on BMC’s official photos of the series) include:

• Precision long pivot bolts with thread-locking compound ready
• Anodized aluminum spacers and bushings
• High-quality washers and retaining clips
• Everything needed for a clean, play-free rebuild

The black oxide or anodized finish matches the modern look of Speedfox frames perfectly. At around $79 USD, it’s a worthwhile investment compared to the cost of new bearings or worse – a compromised ride feel.

Why Choose the Official BMC Bolt Kit – No 19 Over Aftermarket Options?

Many riders wonder if cheaper generic pivot bolts will do the job. Here’s why the genuine Bolt Kit – No 19 is worth it:

• Perfect fit and tolerances – No guesswork or filing required
• Factory torque specs compatibility – Avoid over- or under-tightening issues
• Durability – Engineered to handle the same forces as your original hardware
• Warranty-friendly – Keeps your BMC frame warranty intact
• Black aesthetic match – Looks factory-fresh instead of shiny or mismatched

Aftermarket kits often use slightly different materials or finishes that can lead to premature wear or creaking. With the official kit, you’re simply swapping like-for-like parts.

Step-by-Step: How to Install the Bolt Kit – No 19 (With Pro Tips)

Important disclaimer: Suspension work involves safety-critical components. If you’re not confident with bike mechanics, take your Speedfox to a certified BMC dealer or professional shop. Proper torque and alignment are essential.

General installation outline:

1. Prep your workspace – Clean bike, torque wrench, blue Loctite (if not pre-applied), and suspension-specific tools.
2. Remove old hardware – Support the frame, remove the shock if needed, and carefully extract worn bolts and clips.
3. Clean everything – Use isopropyl alcohol and a soft brush on pivot points and bearings. Inspect for damage.
4. Install new bolts from the kit – Start with the longest pivots, hand-thread first, then torque to BMC specs (typically 8–15 Nm depending on location – check your manual).
5. Reassemble and test – Cycle the suspension through its full travel several times, check for binding, then take a short easy ride to bed everything in.

Many owners report the bike feels “like new” again – smoother small-bump sensitivity and zero creaking after installing the Bolt Kit – No 19.
