Take your chain retention to the quiet, simple, light level with SRAM's X01 X-Sync Chain Ring. It features SRAM's X-Sync narrow/wide tooth profiles to securely hold a chain through the roughest terrain, no chainguide required! A variety of sizes ranging from 30T to 38T let you dial in your rig for your ride. The unique chainring design allows you to slide the ring over the crank arm, so crank removal is not required. Available in 94mm BCD for SRAM's X1 cranks, or 104mm BCD to convert your standard crank to a single-ring system.

SRAM's X-Sync technology ensures a perfect fit between the XX1 chainring and XX1-specific chain for unheard of chain stability with no slap, no drops and no chainguide or weight penalty!

How to measure chainring Bolt Circle Diameter (BCD).

To choose the correct chainring, 1) determine the number of teeth (they're usually marked, or simply count them), 2) determine how many bolt holes there are (usually 4 or 5), and 3) determine the Bolt Circle Diameter (BCD; see diagram).

Common BCDs include:
130mm (Shimano Road)
135mm (Campagnolo Road)
110mm (Compact Road)
104mm, 94mm, and 64mm (Mountain)

Finding the number of teeth and bolts holes is easy. If you don't know your chainring's BCD, measuring it is tricky. So, instead, measure the exact distance (center to center) between 2 adjacent bolt holes. Then find that number on the correct chart below to determine the BCD for your chainring.
