Well, here's my 2009 Allez Sport in oem trim................(it never made it home from the shop when buying it like this tho)
Lots of parts later and 3.5 lbs lighter..............(only frameset = oem)
FSA Team Carbon Crankset, USE carbon aero seatpost, carbon stem, carbon aero bars, carbon pattern bar tape, carbon bottle cage, black 105 rr der, red alloy der pulley, SRAM Rival brakes, dura ace cassette, Cateye Strada red wireless computer, egg beater pedals, Specialized Avatar Gel seat, Bontrager Race XLite wheelset, Bontrager 3x puncture resistant kevlar 700x25 tires..........everything swapped saved as much weight as possible without bumping up 300.00 for each part to save just a few more grams. Wasn't worth it to go any further with an aluminum frame. Went from being 21.5 in oem trim to just under 18lbs as is.
