[G-out]

Somehow I managed to deform my trusty 521 back rim. As my antique bike still has rim brakes, the bulge now causes a pulsing under braking. The spokes are all good, the rim doesn't wobble and I didn't even flat so I'm not sure how it happened but what's the fix?

I've had one friend tell me the only option is to use a couple blocks of wood - one inside the rim, another outside and try to beat it back the way it was?

Any suggestions? Any tricks for the wood block approach?

You can use a couple of adjustable wrenches to re-shape the rim track. Use one to hold the track where it is straight and the other to bend the track in the required direction. With a bit of patience the rim should be almost as good as new.
