I'm having great fun on my recently acquired fixie but one thing I'm having problems with is going downhill fast.

On the steepest hills my top speed is limited by my highest spin, obviously. Once I've reached this RPM I'd like to stop the bike going faster using my legs rather than the brake but I can't get the hang of resisting the pedals when they're rotating really fast.

When I can't spin any faster and start trying to resist the pedals, the whole bike starts wobbling and feels like it's going unstable. I have to give-up and use the brake instead, which kind of sucks. If anyone could share any tips or techniques I'd be really grateful.
