This means a greater gearing range for bigger adventures better chain security for rough terrain and lighter weight and reduced complexity for the daily commute.

The result is ideal for riders looking to convert their road gravel cyclocross or commuter bike to the simplicity and light weight of a single chainring.Not Compatible with Tiagra 4700Compatible with most road CX and gravel bikesDesigned to mount directly to adjuster-free cable stops on Shimano rear derailleursCertain chainring and cassette configurations benefit from a GoatlinkIf the rear derailleur cable is routed internally through the chainstay and exits at the end of the chainstay above the axle or past the axle out the very end you will need to utilize the inline ferrule Speed 11-Speed
