My BB is toast because I can wiggle my cranks back and forth and it's not the cranks because I tried tightening them last night. I can still ride it but it needs to be replaced. Is there any way to order the correct size without taking out. Reason is that it will take 2 weeks to get the part from Nashbar/ Performance and I still need to ride it to work. I'd really like to avoid, taking out, measuring, re-install bad part, new part arrive, uninstall old part again, install new part.
This is a cyclocross bike, some knock off from Korea but I believe it is road geometry, same as a Specialized road bike. Takes regular newer Ultegra crankset. Can I assume it is some standard road size BB, what 68mm english thread?
