Ultegra Crankset
Quote | Reply
I am currently getting a new bike built for myself and just want to make sure that I am understanding the Shimano spec sheets correctly: for an Ultegra crank (R8000) is it only available with a 110mm BCD?

If I want the option to install larger chainrings in the future (I am starting with 53-39), will I be able to with this crank? Eg. upgrading to a 54-42 or 55-42. Or would I need a 130mm BCD crank in order to accomplish this?

Thanks!

Yes, but BCD is not a relevant thing for Shimano cranks. It seems that everyone else only offers the 53/39 chainrings in the large BCD and the smaller chainring sizes in the smaller BCD option. Shimano simply offers all chainring sizes in a single BCD.
