Choosing the Correct Version

Before You Decide
Confirm the handlebar clamp size, fork diameter and stem length match your bike before you choose. If you need a different fitting size, a different stem version will be the better option. The four-bolt clamp design and aluminium construction are part of the listed configuration, so make sure that is the setup you want.
