Product Details

Overview & Technology

Truvativ M8 capless crank bolts (Part #11.6115.115.000 / SRAM FC-SPP-A0) are engineered as OEM replacement hardware for Square‑Taper and Powerspline crank systems. Supplied as a bag of two, these capless bolts provide direct tool access and a compact, service‑friendly profile that keeps your drivetrain secure without extra plastic caps to lose. The bolts are manufactured from heat‑treated high‑strength steel and finished with a corrosion‑resistant coating to resist salt and mud typically encountered on mountain rides. The capless M8 design provides straightforward installation and removal while maintaining clamping integrity under pedaling loads.

Key Features & Construction

Built for strength and longevity: the bolts use heat‑treated alloy steel for high tensile strength and a protective finish for corrosion resistance. The capless head reduces parts and offers direct access for common hex or socket tools, simplifying routine maintenance. Real‑world benefits: • Compact capless head reduces snag points and eliminates lost plastic caps. • Heat‑treated steel construction keeps clamping force consistent under load. • Corrosion‑resistant finish prolongs service life in wet, muddy conditions.

Fit, Compatibility & Specs

These bolts are M8 capless crank arm bolts specified for Truvativ/SRAM Square‑Taper and Powerspline crank interfaces. They match OEM replacement dimensions and mounting geometry for direct swap‑in compatibility on many cranksets that use the M8 fastening standard. Specs at a glance: M8 capless bolt, heat‑treated high‑strength steel, corrosion‑resistant coating, bag of 2. Check your crank's manual or part list for manufacturer compatibility and always use the crank manufacturer's recommended torque specification when installing.

Who It's For

This small but essential part is ideal for mountain bikers who need a reliable OEM replacement for stripped, lost or corroded crank bolts. It's a practical component for home mechanics, shop techs, and riders servicing older bikes or restoring OEM drivetrain hardware. If you run Square‑Taper or Powerspline cranks and want OEM‑grade fastening with a low‑profile, serviceable design, these Truvativ M8 capless crank bolts are a straightforward, durable choice.

Frequently Asked Questions

Will these bolts fit my crankset?

These Truvativ bolts are M8 capless fasteners designed specifically for Square‑Taper and Powerspline crank interfaces used on many Truvativ/SRAM cranksets. Verify your crank uses an M8 crank bolt; if in doubt, check your crank's service manual or the manufacturer's parts list for compatibility.

What tools do I need to install or remove these capless bolts?

The capless design gives direct access for a standard hex/Allen driver or socket; use the driver size specified by the crank manufacturer. Note that removing the crank arm itself typically requires a compatible crank extractor for Square‑Taper or an appropriate removal method for Powerspline cranks.

Are torque specs included?

The bolts do not include a torque value on the packaging. Always tighten crank bolts to the torque recommended by your crank or bike manufacturer to ensure proper clamping without risk of damage.

How many bolts come in the package?

This product ships as a bag of two crank bolts — enough to replace both bolts on a single crankset that uses two‑bolt fastening, or as a pair of replacements for most common installations.

Can I use these to replace capped crank bolts?

Yes, capless bolts are often used as direct replacements for capped hardware as long as the thread size and head geometry match. Capless bolts eliminate the need for plastic caps and allow direct tool access, but confirm head fitment and length before replacing.

What maintenance do these bolts need?

Inspect crank bolts periodically for tightness and corrosion, especially after wet or muddy rides. Clean mating surfaces and apply the manufacturer's recommended thread treatment if specified; always re‑torque to spec after initial rides.

Buying Guide

When buying crank bolts, confirm the thread size (M8 for these Truvativ bolts), head style (capless vs capped), and compatibility with your crank interface (Square‑Taper or Powerspline). Choose OEM or OEM‑equivalent hardware when possible to maintain correct fit, clamping geometry, and safety. Look for heat‑treated, corrosion‑resistant materials and verify the package quantity—these come as a bag of two. Keep spare bolts in your toolbox for on‑trail repairs and always install to the crank manufacturer's torque specification.
