Hi we are building a drop bar conversion on a Rock Hopper that currently has a shimano 8 speed free wheel. We want to upgrade to a Triple ring in front. An older peugot was given to us that has a Sugino triple crank. My question is will I be able to use this crank? I will likely have to replace the BB? Thanks in advance to anyone who can hel. We are completely replacing the drive train and currently are scheduled to get New Sora Front and Rear Derailleurs. Of course we will get the right ones depending on if we go three ring or 2.
