Shimano 105 vs Ultegra BB ??s(3 posts)

Shimano 105 vs Ultegra BB ??sChef
Nov 5, 2002 8:08 AM
Good morning all,

I'm switching frames, and while the majority of my Ultegra components can make the transfer easily the BB has to go from English- to Italian-thread; obviously, I need a new BB. I currently use an Ultegra splined BB, English, double - but would a 105 splined be compatible with my Ultegra cranks? I'm trying to save some money, and frankly I could care less whether there's a 105 or Ultegra BB in the frame.

Thanks in advance for any assistance.

No problems, the 105 is the same length and spline pattern, just a bit heavier. I had a 105 bb on a former bike and had no issues whatsoever.
Thank you! nmChef
