42 Tooth Singles for Cyclocross & Gravel

The new 42 tooth Z-rings fit many standard 110 mm BCD cranks.  Select the crank style in the options pull-down menu above.  The Z-Rings are made for conversion, so they work on most cranks with a 110 mm bolt circle.  It’s a simple conversion that will make a double into a single ring (1X) drivetrain.

Converting from a double:  Check the crank bolt pattern to be sure of a compatible configuration in 110 BCD.  Order correct rings by selecting the correct option in the pull-down menu above.  If you prefer to use Conversion Tabs, order those and standard length bolts.  If you prefer to mount the Z-Rings directly to the crank tabs, get a set of the Shorty Bolts.  If the crank is compatible, the conversion does NOT require a new crank!

For best and fastest performance, we recommend a New Chain with new rings, and Chain Lube to make it all run smooth!
