Hi

Very quick q - basically, question of degree rather than anything else.

I hit the l/h crank on my fixie on the kerb trying to avoid a taxi, and since then have had a tiny bit of vertical play in the crank - about 3mm or so. It feels like the play you'd get from a properly tensioned chain, but it's just on the crank - if I hold the r/h crank still and rotate the l/h crank, it moves the 3mm or so up/down.

I figured at first I'd just loosened it, so removed the crank, greased the bolt and the spindle, torqued up the crank bolt and the movement went.

It's now come back - within about 20 miles of riding - so I figure I might have slightly rounded either the BB taper or the crank socket.

So - any suggestions on what the best course of action would be? I'd prefer not to replace the cranks or the BB as they're only about a year old, but if it's an accident waiting to happen I will.

Cheers!

edit - Sugino RD square spindle cranks, matching BB.
