Although disc brakes pretty much remove the issue of a buckled wheel, you can still suffer the consequences of a big hit on a downhill. Now, it has to be a really big smash for your wheel, but, in some cases you can bend your disc brake rotor. This is something that you need to fix ASAP – bent rotors can play havoc with your disc brake pistons and more.
There are a couple of fixes for this one. If you still want to use your brake (we’d recommend this route), try bending it back like we show you in the video.

Top tip: After mending it by hand, ride for a while with the brake on (just
enough to still keep the wheel turning). You’ll find it gets quite a lot
better after about 1km :)
