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!
