Standard V brakes, they work great with the top mounted cyclo X levers, OK with the drop levers but will work better with the ones that Tektro make for V brakes that work really well, they are £25 and are on order, I have them on my other bike, I will then use bar end changers, the stem is 120mm and its fine for me, here it is again......work in progressNice bike. That replacement stem is looooong! Did you get mini-vbrakes or get some pull adapters?
