When you're transferring your wheels from steed to steed, you're bound to have some compatibility clashes here and there. Let Stan's NoTubes help solve the problems with the Neo End Caps. These handy end caps are available for a variety of wheel standards, and easily install on the ends of your hubs to extend compatibility beyond the wheelset's original standards. They fit both the Stan's Neo and Neo Ultimate hubs, and are available for either six-bolt or centerlock brakes, so be sure to pick the right option for your current wheel setup.
