I've decided to start upgrading my Drive-Train on my 1600, but I know little to nothing about compatibility. So far, I've only put a Dura-Ace chain on (really, really, quiet). Now, I've been contemplating about getting either an Ultegra FD or an Ultegra crankset. The FD would be easy since my LBS carries them and can help me choose the right one. However, I really would like a crankset, and my LBS doesn't carry cranks higher than 105. So....
I'd like to get a double crankset, but I'm nto sure what model I'd have to get.
a) Would I have to buy a new bottom bracket, or would it work with my 105 BB?
b) What model would I have to get?
c) Would this work? Ebay #270051924551
I'm liking the price, but there's no model number. Also, it's nine speed. My cassete is 10spd, so I'm not sure how that'll go down. But, some parts are compatible, IE. Dura-Ace 10spd chain can go on a 9spd
