S100 Eagle Boots Crankset - Powerspline Bottom Bracket, B1

SRAM S100 Eagle Boots Crankset delivers a durable, no-nonsense 1x setup for riders who want consistent chain control and long service life without chasing ultra-light weight. Built around stiff aluminum crank arms and a hard-wearing steel X-Sync 2 chainring, it brings proven Eagle-style chain retention to everyday trail, all-mountain, and e-bike-adjacent abuse where durability matters most.

This crankset is designed for the SRAM Eagle Drivetrain Ecosystem and uses a 3-bolt chainring interface for secure mounting and straightforward service. It requires a PowerSpline bottom bracket (118/73, sold separately), making it a practical choice for PowerSpline-equipped builds and budget-conscious replacements.
