Absolute Black Sram BB30 Narrow-Wide Chainring

Is This it? #01
In Stock Reminder

Product Description

Absolute Black's XX1 style chainring for SRAM short spindle BB30 cranks is a simple upgrade for your 1x drivetrain. These rings utilize the narrow-wide technology, making them ideal for single speed, 1x9, 1x10, and 1x11 drivetrains. The chainring is machined to fit perfectly with the outer and inner plates of the chain, keeping the chain firmly in place without a chain guide. This Narrow-Wide design ensures reliable performance, even on the roughest of terrain. It is recommended that this chainring be used with clutch type rear derailleurs in order to minimize or eliminate chain drop. Each chainring weighs significantly less than the stock SRAM XX1 chainring and spider.

Crank Compatibility

SRAM's line of BB30/PF30 compatible cranks feature two different spindle lengths - a "long" 101.5 mm spindle, and a "short" 95 mm spindle. The spindle length is most easily identified by measuring the width of the crank's drive side spacer; long spindles are equipped with a 15 mm spacer, and short spindles are equipped with a 9 mm spacer. Additionally, compatible SRAM cranks will feature splines and three bolts to mount the chainring or spider. Compatibility is mixed across SRAM's product line, so cranks should be visually inspected before ordering.

This chainring is designed for proper chainline when used with a BB30/PF30 short spindle. For long spindles, or when using a 28 tooth chainring with a BB30 short spinde, please order the standard GXP-compatible chainring.
