damage after crash.

Hi all.

I had a crash with another cyclist last weekend which would of been nasty had we not of been wearing helmets. Anyway, I was unaware that any damage had been done to my bike. Got it out today to clean it and my crank is really stiff to turn. Back peddling is really stiff to. I fear that the bb is knackered? Could this be possible? Could a crash knacker the bb?

Cheers

Possibly mangled rear mech? take the chain off and spin the cranks, if still stiff then BB is most likely cause but its unusual to damage BB in a crash. If it only does it with chain on there is an issue elsewhere. Pictures?

Yeah. I had already tested it without chain and it still does it. There is no visible damage

Cranks bent? What kind of BB? If external type, are the BB cups still sitting flush with the frame? If all looks as it should I can only suggest whipping the cranks off and having a look/replace BB.

Everything appears to be OK. It's a hollowtech 2. I don't have the tools to remove it; it's a job for the lbs but will get a bb from chain reaction as they are much cheaper.

I think this is what I need http://www.chainreactioncycles.com/mobi ... -prod34674

Doubt a crash would but damp might. Don't get that though, spend a little more and get XT or XTR. They last much longer - sealing in much better.

Just seems a massive coincidence. I was knocked off sideways so pedal may of hit floor at some force. Will get bike shop to check it over. Wanted to pick a cheap one up for now so I have one to take with me but knowing that it could be something else that is wrong.
