Box Four narrow/wide chainring for use with the wide ratio Box Four drivetrain
The tooth profile and thicknesses are tailored to match the inside geometry of the unique Box Four chain
Intended for use with the Box Four drivetrain only - may not function ideally with other 8 speed drivetrains

A tight and consistent 13-tooth gap between chainrings delivers accurate and dependable shifting and is the core of Sram`s X-Range gearing
X-Range gearing technology gives you more range and a smoother gear progression, so you`re always in the right gear
Crisp and accurate front shifts
Durable finish

Designed for use with a 104 BCD interface of any 104 BCD spider, this chainring utilizes Sram`s T-Type design and is backwards compatible with EAGLE technology (X-SYNC II)
SRAM drivetrain engineers optimized this ring to combat the high-torque, high-wear situations e-bike riders face
The aggressive tooth design provides better chain retention for a smoother, more efficient pedal feel with a focus on long wear-life
