Made a few changes with old parts: (Captain) Bars/stem/tape from 2011 Madone 5.2, WTB Saddle, (Stoker) Thomson Seatpost, Terry Carbon railed saddle, Nitto alloy bars cutoff and flipped to form bullhorn, old beater 3T fixed stem. These no-dollar changes with stuff from the parts-bin knocked of 2 pounds from 33.2 lbs. to 31.2 lbs.
I found the Trek on Craigslist a week ago for a good deal. It obviously has ridiculously low miles - original tires with gobs of tread and hardly any wear on the brake pads. I weighed the tires and they are 390 grams each. The wife said she'd like new tires for piece of mind so a couple Michelin Pro4 Endurance 25mm tires are on the way (around 250 grams each). I also weighed the cassette (SRAM PG970) and it's 430 grams. Might pick up an clearance XT cassette that should shave another 100 grams. Might pick up a Shimano Pro stem to shave 60 - 70 grams. I don't think I can get it under 30 lbs. without upgrading the wheelset but it still might get close. Still not bad for only $1,500. I like good deals. I forgot how good 9-speed Shimano drivetrains shift.
