Hey guys,

I'm deciding to buy a Dolan Pre-Cursa Frameset because it's a frame that I like and fits my budget/dimensions.

That being said, it will not have a crankset or bottom bracket -- I'll be transferring (hopefully) the bottom bracket and crankset from my other bike to the new one.

The problem is that the bike that I currently have was also a secondhand fixie that had a mix-mash of parts.

Anyone know how to check the bottom bracket specificity before having to take the bike apart and finding out?

I believe the current fixie I have has a Retrospec frame, although I haven't seen any branding of any sort besides the wheels.

Any advice regarding swapping parts from one bike to another would be appreciated!
