CXTony...I took your advice and picked up a set of Stan's 2012 Iron Cross wheels w/Clement PDX Tires and Stan's sealant installed. I ignored the warning and told my friend to keep pumping past 45 psi...they blew off the rim at 65. What a mess! I should have done a little more research before getting the Iron Crosses. They're really light but won't take the pressure I want to run. I weighed them when I got home and they're 1lb 1oz lighter, per wheel than the stockers, very happy with that. They also came with an ultegra 11-28 cassette which is lighter than the stock 105 cassette of the same ratio (43g less).
To run higher pressure I ordered some Stan's Alpha 340's on sale for $95 each. They're the same weight (385g) but aren't pressure limited like the Iron Crosses are. And some 28mm 226g Compass 28's and 77g Michelin tubes. Should put the whole bike around 20lbs, hopefully a hair under, with pedals.
I'm wondering what I could save with the seatpost and handlebar?
small aside: The FSA Gossamer BB30 has seemed to develope a creak sound in the BB, does anyone know how to get rid of it?
Thanks again for the help
