Ok, I need to replace the cassette and chain on my road bike, as they are worn.
My bike is a 2007 specialized Roubaix Elite Triple - 105 derailleurs and cassette (10 speed)
the cassette is 12-27, and the chainrings are 50-39-30
not sure if it matters, but about 7 or 8 months ago, the RD god sucked into the spokes (bent hanger?) and destroyed. I replaced it with a new 2009 105 RD.
Anyway, I understand that I _can_ replace the chain and cassette with Ultegra instead of 105, but what I want to know is..., is there any particular reason to do so. The price difference is minimal, so if there were any reason to expect better shifting, I would do it.
on the other hand, i guess it's possible that the 105 RD and FD will work better with the 105 chain...
So, which is it:
a) ultegra cassette and chain will shift better than 105 cassette and chain
b) 105 cassette and chain will shift better than ultegra cassette and chain
c) no perceptible difference
also, other than counting the links, how do i know what size chain to get?
