Finally built and ready to ride over the weekend.
Trek 9.9ssl carbon frame, size 19.5, 2009 model, plus carbon post
RS Reba Race 2010 forks
Complete XT brakes and gears
Thompson stem and Specialized bars off a friends Stumpjumper, thanks Matt
Selle Italia filante saddle
NN and RR rubber
Basic but indestructible SPD's
Not super light, I guess around 24.5lb, could loose 2lbs without breaking the bank, but quite frankly I'm gonna get loads of miles in first, as I'm starting to believe that weight ultimately doesn't really matter that much.
Thanks to njee20 for the help with a couple of simple to questions.
