Product Details

Crank Bolt Overview & Technology

Truvativ M15 capless crank bolts (Part #11.6900.002.050, SRAM Model ID FC-SPP-A0) are a simple, robust solution for securing crank arms on ISIS and Howitzer spindle systems. Sold as a bag of two, these bolts are purpose-built for mountain bike cranksets where a compact, capless head reduces interference with frame clearance and keeps the look clean. Construction and finish: The bolts are made from heat-treated steel with a corrosion-resistant coating to withstand trail conditions and repeated removal. The M15 designation refers to the bolt type/size used in many Truvativ/SRAM systems and ensures reliable thread engagement with the crank interface.

Key Features & Benefits

Durability and fit: Heat-treated steel construction delivers high clamping strength and fatigue resistance for everyday trail riding and regular maintenance cycles. The corrosion-resistant finish helps prevent seizing in wet or muddy conditions. Low-profile capless design: The capless head keeps the crank arm surface flush for improved pedal clearance and easier access when using crank removal tools. The package contains two bolts — enough to replace both crank-arm fasteners on most single-crank installations. • Heat-treated steel for strength and longevity • Capless head for reduced interference and cleaner looks • Specifically sized M15 for ISIS and Howitzer crank systems • Sold as a pair—ideal for replacing both left/right bolts

Fit, Compatibility & Installation

These bolts are designed specifically for ISIS and Howitzer spindle interfaces used on many Truvativ and SRAM cranksets. Confirm your crank uses M15-style bolts before purchasing — the bolt head and thread engagement must match the crank’s insert. They are not universal for all crank types; check your crankset manual or existing bolt markings. Installation is straightforward: clean threads, apply light threadlocker if recommended by your crank manufacturer, and tighten to the crankmaker's specified torque using a torque wrench. If you’re unsure of the correct torque, refer to your crankset’s documentation or consult a professional mechanic to avoid over- or under-tightening.

Who These Crank Bolts Are For

These Truvativ M15 capless crank bolts are ideal for mountain bikers who need a direct replacement for ISIS or Howitzer-compatible cranksets. They suit riders doing regular maintenance, swapping cranks, or replacing lost/damaged bolts after crashes or servicing. Mechanics and home wrench-enthusiasts will appreciate the authentic OEM fit and finish, while bikeshops can keep them as a compact, high-turnover spare part for common SRAM/Truvativ crank systems.

Frequently Asked Questions

Are these crank bolts compatible with my crankset?

These bolts are made for cranksets that use M15-style fasteners, specifically Truvativ/SRAM ISIS and Howitzer systems. Confirm your crank manual or inspect your existing bolts for M15 marking. If your crank uses a different bolt/head type, these will not fit.

How many bolts come in the pack?

This Truvativ part is sold as a bag of two bolts—enough to replace both crank-arm fasteners on most single-crank installations. For multi-piece cranksets that use more bolts, you may need additional packs.

What material are the bolts made from?

The bolts are manufactured from heat-treated steel with a corrosion-resistant finish to provide strength and resist trail-side corrosion. This combination balances durability with affordability for a reliable OEM replacement.

Do I need any special tools to install them?

Installation requires the proper hex or multi-tool that matches the crank’s internal interface and a torque wrench to tighten to the crankmaker’s specified torque. Use of threadlocker is sometimes recommended by manufacturers—follow your crankset’s service instructions.

Can I reuse these bolts after removing them?

Bolts can be reused if they show no signs of thread damage, distortion, or corrosion. Inspect threads and heads during removal; replace if there is any wear. When reinstalling, follow the recommended torque and service procedures to ensure safety.

What if the bolt won’t tighten or strips?

If the bolt does not tighten or strips, stop immediately to avoid damaging the crank threads. Clean debris from the crank insert, check for cross-threading, and if damage is present, consult a bike shop—thread repair or insert replacement may be necessary.

Buying Guide

When buying crank bolts choose the correct bolt type (M15, M20, etc.), head style (capless or capped), and material. OEM bolts like these Truvativ items ensure exact fit for ISIS and Howitzer crank interfaces and remove guesswork about thread pitch and head dimensions. Look for heat-treated steel for durability, and consider keeping spare bolts on hand if you frequently service your drivetrain or swap cranks. Always follow manufacturer torque specs and installation instructions for safe, reliable performance.
