Product Details

Overview & Technology

SRAM SBC Mahle Bolt Kit is a purpose-built chainring fastener set for SBC Mahle e-bike crank systems. Manufactured from precision-machined aluminum, these M10x0.75 bolts deliver a corrosion-resistant, lightweight solution designed specifically for the loads and spacing of modern electric-assist drivetrains. The kit includes T30-drive bolts and the critical spider adjustment screw that sets correct chainring spacing and preload on the Mahle SBC spider. That small adjustment screw ensures consistent chainline and keeps the chainring centered under high torque from e-bike motors.

Key Features & Benefits

Purpose-built hardware: M10x0.75 thread pitch matches Mahle SBC cranks for a positive, secure fit under e-bike torque. The kit's aluminum construction balances strength with minimal weight—shipping weight is only 0.1 lb. • T30 drive: Common Torx head for reliable engagement during installation. • Spider adjustment screw included: Enables precise ring alignment and preload without requiring extra parts. • Corrosion-resistant finish: Aluminum fasteners reduce weight and resist rust in wet conditions.

Fit & Compatibility

This bolt kit is engineered for SRAM Model ID CR-SPP-A0 and Mahle SBC crank spiders using M10x0.75 chainring bolts. Use it when your crank spider specifies M10x0.75 fasteners—do not substitute if your crank requires a different thread pitch or bolt length. While the kit fits the Mahle SBC interface, compatibility with other crank spiders depends on thread pitch and spacer requirements. Always verify part numbers (SRAM 400222 / 11.6918.007.001) and consult your crank or bike manufacturer's installation manual for torque specs and fitment notes.

Who It's For

Designed for e-bike owners, mechanics, and shops who run SRAM SBC Mahle cranksets and need OEM-spec replacement hardware. If you service Mahle-equipped e-bikes regularly, this kit provides the correct bolts and the spider adjustment screw so chainrings perform reliably under motor assist. It's also a smart buy for riders planning upgrades or repeat maintenance—lightweight, OEM-matched fasteners give peace of mind on long rides and technical terrain where chainline and secure attachment matter most.

Frequently Asked Questions

Will this bolt kit fit non-Mahle cranks?

This kit is designed specifically for SRAM SBC Mahle crank spiders that use M10x0.75 bolts. It may fit other cranksets only if they share the same thread pitch and bolt geometry—but always confirm your crank's specifications before installing non‑OEM hardware.

Does the kit include the spider adjustment screw?

Yes—the kit includes the spider adjustment screw necessary for setting chainring preload and alignment on the Mahle SBC spider, so you get everything required for a proper installation.

What tools do I need to install these bolts?

You will need a T30 Torx driver for the bolts and a suitable tool for the spider adjustment screw (check your crank manual). Install bolts to the manufacturer's recommended torque settings—if unsure, consult SRAM or a professional mechanic.

Are these bolts corrosion resistant for wet riding?

The bolts are machined aluminum with a corrosion-resistant finish. While aluminum resists rust, regular inspection and light lubricant or anti-seize on threads can further protect hardware in salty or very wet environments.

Can I reuse the bolts after removal?

Bolts can typically be reused if they are undamaged and threads are in good condition, but for critical fasteners on e-bikes subjected to high torque, replacing bolts during servicing is recommended to ensure long-term security.

What is the part number and how do I verify it's the right kit?

SRAM part number for this kit is 400222 and manufacturer part # 11.6918.007.001. Match these numbers with your crankset documentation or consult Forest Bikes' product page to confirm compatibility before purchase.

Buying Guide

When choosing chainring bolt kits for e-bikes, prioritize correct thread pitch, material, and inclusion of any special adjustment hardware. Aluminum bolts offer a good weight-to-strength ratio for many applications, but ensure the kit includes any spider adjustment screws or spacers your crank requires. Look for OEM or crank-specific kits (like the SRAM SBC Mahle kit) to avoid fitment issues. Plan to replace bolts that show thread wear or galling, and always install to manufacturer torque specs with the proper tools for reliable, long-term performance.
