What type of bottom bracket will this bike have?

Hi all,

So I just ordered a new aluminum tri bike. I want to replace the crankset with a Shimano Hollowtech II one so I can swap my left-arm power meter back and forth between my road bike and tri bike.

Based on the photos, it seems like it's a self-extracting crankset, but I can't tell much about the bottom bracket standard (BB30 vs BSA vs ???). Just want to make sure I'm ordering the right bottom bracket as I won't get the bike for another week. Thank you!

Bikes: Too many. Giant Trance X 29, Surly Midnight Special get the most time.

A crazy idea—contact blue. Bb shell type cannot be determined from your photos and isn't listed on their website.

It'll have either a BB30 or a 19mm axle.... https://shop.fullspeedahead.com/en/omega-crankset-3912 GIYF

I'll bet that the manufacturer would give an authoritative answer.

Unfortunately, they didn't -- They said Shimano only makes one standard and that it should fit with the current BB -- which wouldn't make sense since AFAIK, FSA uses a different spindle size than Shimano.

Looking at the first photo, it kind of looks like a press-fit cup to me, but I've never had a press-fit cup before to compare it to as all of my external cups have had ridges (for a BSA frame).

Id agree that the photo looks press fit. If they are saying it’s Shimano it will be PF86. FSA crank is probably Mega EXO/Hollowtech II compatible, 24mm. *Should* be able to put a Shimano crank right in it and roll.

Waiting 6 more days for it to arrive isn't an option?
