Aaaargh!

For some reason, the chain has started to part company with the rear sprocket. I know it's speed related - centrifugal force is causing it to lift off, bang the hub spacer and come off. Six times last night on an 8 mile commute. It's been fine since the conversion to SS (about 3 weeks) so what's gone wrong and how can I stop it?

Merci!

the chain has stretched/worn slightly or the hub has moved int he dropout.

retension and it'll be fine.

No tensioner. Just a BMX setup.

How do I re-tension?

Just slacken the axle nuts, pull the wheel back and nip the nuts up again surely?
