Absolute Black's XX1 chainring for SRAM GXP cranks is a welcome upgrade to SRAM's single chainring drive trains. Each Absolute Black chainring utilizes Narrow-Wide technology, making them ideal for 1 x 9, 1 x 10, and 1 x 11 drivetrains. Essentially, the chainring is machined to fit perfectly with the male and female shapes of a chain, guaranteeing extremely reliable chain retention abilities. The Narrow-Wide tooth profile, holds the chain on the chainring without a chain guide during pedaling, coasting and backpedaling even on the roughest of terrain. The Absolute Black Narrow-Wide chainring can be used in tandem with, or independently of clutch equipped derailleurs in order to minimize or eliminate chain drop. Each chainring weighs significantly less than the stock SRAM XX1 chainring and spider.
Due to the nature of the finish of Absolute Black products, the chainring you receive may not EXACTLY match those depicted.
There are two different axle length options when purchasing a SRAM crank. The longer axle — the axle this ring is designed for — is easily identifiable by measuring the drive side axle spacer. A 15mm wide spacer is for the long axle, if your spacer is 9mm wide you need the SRAM XX1 short Chainring
. This small yet important difference comes in the chainring spacing and chainline. Every Absolute Black chainring is carefully engineered to an ideal chainline.
