>>1393585>thoughts?>advice on this kind of brake setup?That's an Odyssey Pro Vapor stem.
there is supposed to be a wheel there. the cable stop at the top is where the housing stops, the cable goes over the wheel. The wheel is not round. It was designed to improve the feel of cantilever brakes.
You will not be able to find a replacement wheel but you can buy a new one on ebay if you insist. Bettwen to buy v-brakes and long pull v brake levers instead
