My current crank is a compact Shimano FC-R600 with BB, I have no idea what size BB this is.. What is all involved in changing cranksets? Can I upgrade to either Ultegra or DA without changing any other components?
Thanks!
Your current crank is 2-piece, there's no BB involved. (Strictly speaking, it is involved, but it's built into the right crankarm.)
You need a couple of specialized tools, Shimano TL-FC16 and TL-FC32. I think you can use ParkTool BBT-22 in place of TL-FC16.
Then you take out your crank, put it on eBay, and install a new one. Procedures involved in installing the new crank depend on the model, but you will most likely need BBT-22 again, and possibly other tools.
EDIT: I stand corrected: you can't use BBT-22 in place of TL-FC16, and I don't think you need TL-FC16 at all to remove the crank, it's called on just to install it.
