HOW TO MOUNT CX OVAL CHAINRING TO SRAM CRANK:

Take the crank off the bike. Unscrew these 3 torx t-25 bolts from the crank arm. Then remove the spider+chainring combo you currently have there. Clean the splines and put some grease on them. Position the chainring in place (note there is only one way to fit this Sram chainring so you don't have to worry how to do it). Close all 3 bolts to about 5-7Nm.



It is ideal for 1x 9/10/11 system and Singlespeeds!. Oval (elliptical) chainring does not compromise the work of clutch mechanism in rear derailleur. It also does not require chain tensioner when using in singlespeed application. Riding out of saddle on the uphill will become more pleasant. These chainrings also help you to recover after knee injuries as pedaling becomes smoother and less exhausting.

The most advanced, Patent Pending narrow/wide tooth profile currently produced, guarantee minimum 12 months of excellent chain retention capabilities! We mean it. Always use a new chain with a new chainring.

Designed in UK. Manufactured in Poland (EU).

Chain options

10 / 11 / 12spd chain for geared bike or 6-8 spd for SS. If used in 1x9 drivetrain - 10spd chain must be used to obtain the performance. (yes - 10spd chain will work great on 9spd cassette)

Chainguide needed?

No. But if you want one then chain guide should have 2 teeth more capacity than nominal oval ring size.
