Hi, I've been racing both road & XC for close to 20 years and after hearing about how much fun this thing called cyclocross is I've finally broke down and purchased a cross frame (2003 Giant TCX)
I am currently building it up using some old parts from the "bin". I have a couple of questions for you.
I am using a Dura-ace 8 spd gruppo with a 12-23 cluster and have a couple of options for the cranks. The original DA 53-39 set up or I could use an FSA gossamer compact w/ 50-34 that I currently use on my roadie. I would prefer to use the D/A and not butcher my road bike, I notice that most stock bikes come with 48>50 X 34>36 or there about. will I be at some sort of disadvantage using the D/A? how about a single 42 tooth chain ring up front? BB compatibility is not an issue as I have quite a few kicking about.
secondly; what air pressure ranges are you guys running? I've bought some Michelin clincher tires with a range up to 80 psi.
lastly;I have a set of Salsa cross brake levers that used to be on my commuter, I took them off because I never used them, are they really necessary for cross racing?
Thanks for any feedback I post some pics when she's built.
