In the search for ultimate durability Campagnolo has made their outer bearing races replaceable for many years. That doesn't mean that anybody has bothered to make tools for doing such a repair though. We are able to make these drifts to order for both the new 2015 front hubs and the 2014-1998 rear hubs. Our drifts are made from solid brass and are designed specifically for the Campagnolo angular contact bearing. These tools are built to order, allow 2-3 weeks for delivery. These drifts are sold as singles. Style A is for front and rear individual hubs made after 1998, rear hubs in Campagnolo wheels made up-to model year 2014 and front hubs in Campagnolo wheels made up to 2014 Style B is for front hubs in Campagnolo wheels for model year 2015 and newer. However, they WILL NOT fit disc hubs. Handmade in Bend Oregon.
