Hi everyone. I've done a lot of searching on this question, and I *think* I've found the answer, but I'd like a simple, definitive answer if you'll indulge me.
I have the Shimano 105 5800 groupset (53/39, 11 cassette) with the SM-BBR60 bottom bracket. Stages doesn't currently have a 105 5800 left side crank model (although they're supposed to have one by now, I've read). Will the 105 5700 fit? (If not, will the Ultegra 6800 fit?)
Thank you SO MUCH.
