I've recently discovered my drive-side crank arm has a stress fracture. I replaced the left arm for the same reason a few months ago. So, I'll be needing a new crankset.
I was browsing ebay, and came across this:
He says a square taper bb is required, but it appears to be octalink. What's up with that?
Also I have 7 speed, the seller says it works with 8 or 9 speed. Could I make this work?
You should know that My prior crankset was shimano 105. I don't know the BCD, but I'm assuming 130. I also don't know what the bb size is.
