Default help! wasted my bottom bracket bearings
may be a stupid question to some...but the 3 piece wide grubee crank bearings have failed on my bike, can someone tell me the size of them? are they a custom size or will any 3 piece crank bearings work? i just dont want to spend $28 bux( with shipping) for the replacement grubee parts if i dont have to. Thanks a million!

I think any regular bearing from other bikes work.
