I know this has been posted before, but I just wanted to clarify...

I picked up an origin 8 crankset, which says to use 107mm for the BB. From what I've read on some posts, this is a mistake? I should be using 103?

I'm fairly new to this, so I'm trying to make sure I get this stuff right. The guy sold me a 107 BB to fit the crankset, now I'm not so sure.

Eat a ***k, dude.

You said the guy sold you a 107.That sounds like you have it in hand .Just put everything together nice and clean and carefull and see if it works.If it does,take it apart ,grease it and put it together for good.If it doesn't,return the 107 and get a 103.I don't get why so many people come here asking about s**t the already own instead of just measureing it(like what size is my seatpost) or just putting it together.

Try this out, I think it's what you're looking for. Good luck

Because I literally just picked it up. Unfortunately, I don't have a bike workshop in my office, so I thought I'd ask. I called the dude at the store, and he wasn't any help.

Also, thanks CS1.
