I'm very new to road bikes and have got myself in a bit of a mess. I recently bought a nice singlespeed bike which needed a bit of work, namely new brakes, cables, etc.
Now that I come to try and find some brakes I'm struggling to find some that I'm confident will actually fit. I've measured the vertical distance from the central boss to the wheel rim and it's around about 90mm at the front and 70mm at the back. I can't find anything online that would fit this but might well be measuring it wrongly!
The back brake is currently a seized up u-brake, with the front being a central pull cantilever. Ideally I'm looking to fit u-brakes on both front and rear but think I may have to settle for some v-brakes on the front.
Any advice would be very appreciated!
