Product Details

Overview & Technology

SRAM XX 4‑arm double chainring bolt kit is a compact, purpose‑built hardware set for mounting double chainrings on 4‑arm crank spiders. Designed to the same quality standards as SRAM's drivetrain components, this kit delivers the fit and finish needed to keep chainrings tight under load while maintaining a clean, low‑profile look in black. Drive interface: The kit uses a T25 Torx drive for definitive tool engagement and easy installation. Components are precision machined for concentricity and consistent clamping force, reducing chainring flex and improving shifting consistency under power.

Key Features & Construction

The bolt kit combines lightweight, machined alloy heads with hardened, corrosion‑resistant steel threads for reliable clamping and long life. This hybrid construction balances weight savings with strength where it counts — in the threaded interface that resists wear and galling. • T25 Torx drive for secure tool fit and torque control. • 4‑arm / double configuration specifically sized for 4‑bolt crank spiders and double chainrings. • Black finish for a discreet, OEM look that matches most cranksets.

Fit, Compatibility & Installation

This kit is intended for 4‑arm crank spiders using double chainrings and is listed by SRAM under part number 11.6215.193.060 (Model ID: CR‑SPP‑A0). It fits SRAM/Truvativ/Zipp chainrings that accept 4‑bolt hardware and replaces worn or stripped bolts to restore safe chainring clamping. Installation is straightforward with a T25 Torx driver. Tighten bolts evenly in a star pattern and follow your crank manufacturer's recommended torque (typically in the range of 8–12 Nm). Use a small amount of threadlocker if your application calls for extra security, but avoid over‑tightening to prevent damage to chainrings or crank threads.

Who This Kit Is For

Road cyclists and mechanics who run 4‑arm double cranksets and need an OEM‑quality replacement will appreciate this SRAM bolt kit. It's ideal for riders replacing stripped fasteners after chainring swaps, for shop mechanics stocking reliable hardware, or for anyone seeking tidy, matched hardware for a SRAM/Truvativ/Zipp drivetrain. Because the kit is compact and lightweight with durable construction, it's also a good spare to carry on long rides where a lost or damaged bolt could otherwise end your ride prematurely.

Frequently Asked Questions

Which cranks and chainrings does this bolt kit fit?

This kit is intended for 4‑arm crank spiders and double chainrings that use 4‑bolt mounting patterns—commonly found on many SRAM, Truvativ and Zipp setups. Confirm your crank/chainring uses a 4‑bolt layout before purchasing.

What tools do I need to install these bolts?

You need a T25 Torx driver to install and remove these bolts. Use a torque wrench set to the crank manufacturer's recommended specification to ensure even clamping and avoid over‑torquing.

Can I use threadlocker with these bolts?

A small drop of medium‑strength threadlocker is acceptable if you experience loosening, but many users install bolts dry. Always follow component manufacturer guidance and avoid excessive threadlocker that can complicate future removal.

Are the bolts corrosion resistant for wet conditions?

The kit uses a combination of machined alloy heads and hardened steel threads with a protective black finish. While designed for long‑term use, regular maintenance and inspection in wet, salty conditions will extend life and prevent corrosion.

What torque should I use when tightening these bolts?

Follow your crank manufacturer's torque recommendations. As a general guideline for chainring bolts, many mechanics use 8–12 Nm, tightening bolts gradually in a star pattern for even clamping.

Will these bolts work on single (1x) chainring setups?

This specific kit is for double chainring (2x) 4‑arm configurations. Single‑ring (1x) setups often use different spacing or individual bolt/nut systems, so verify compatibility before fitting.

Buying Guide

When replacing chainring bolts, match the bolt kit to your crank's bolt pattern (4‑arm vs 5‑arm) and chainring type (double vs single). Look for kits that use hardened threads and precision heads to reduce the risk of stripping and to maintain shifting performance. If you carry spares on rides, choose lightweight, OEM‑style kits like this SRAM XX bolt set that are compact and durable. Always carry the correct T25 tool and a small torque wrench or driver if you plan to tighten bolts on the trail.
