These are a great upgrade to any Stock BMX or even MTB V-Brake system... Definitely a high enough quality for any lever of BMX racer. But the real value in this brake arm set is the 35mm brake pad adjustment... We have all had that frame where standard brakes will not allow you to run the axle all the way forward in the dropouts on a BMX race bike without buying some sort of adapter that sacrifices brake performance and is costly. Then we bought an adapter kit to find out it wouldn't work on our frame because of some non-standard thread on the posts! Well these brakes, with a generous amount of pad adjustment, will very likely solve those problems without breaking the bank (no pun intended). There may be other solutions out there, but likely not in this price range!
