If you've got a set of Race Face wheels with Vault hubs invest in some spare Vault End Cap- Set and stash them in the toolbox so you won't be up a well-polluted tributary without any means of locomotion on your next road trip. Or maybe you're swapping forks and want to reap the benefits of Torque End Caps. These particular versions install and remove tool-free and both work with 15mm thru-axle forks one with standard dropouts and the other for Rock Shox Torque Cap dropouts. The Torque Cap system involves a more robust dropout and hub interface that increases the contact area with the fork. This makes for a stiffer front end that tracks better when pushed harder. Please note that the Torque Cap End Caps are only compatible with Torque Cap forks.
