Wow.... 2 1/2 pounds of weight savings in just the frameset (I'm guessing just frame and fork?) alone is really pretty quite ridiculous... That's more than a kg!!
After I wrote that I thought that sounded like more than possible. Since I no longer have either bike, I went back to look at the specs from the 2011 Alatmira 3.0. The fork listed in the specs is an FC770 (aluminum steerer listed) not an FC440 (carbon steerer listed on 2013 specs). I remember the fork having an aluminum steerer so it must've been the FC770. Does anyone know what the numbers mean in Fuji's fork naming scheme? The Team LTD model had an FC330. If those numbers refer to grams then the 2 1/2lbs. weight loss makes sense. The Team LTD frame was approx. 840g as I remember and the fork was somewhere in the 340's uncut. The heavier C4 2011 Altamira frame was never weighed separately, but 1300g wouldn't have been a surprise...it was HEAVY and STIFF. So a 770g fork switched for a 340g fork gets pretty close to 2 1/2 lbs. Later on when I switched the 105 crank for the Rotor 3D-f the bike lost another 3/10lb, but that 105 crank was WAY stiffer...Maybe the stiffest crank I've ever ridden (although I'm impressed with the stiffness of the 2012 Red Crank I'm currently riding). Anyway BIG difference between the weight and the ride quality of the top of the line Altamira and the rest of the Altamiras. Felt like a completely different brand/model actually.
I still think there are better & more inexpensive alternatives to Fuji. I'm very leary of Fuji after my experience, although a Performance employee I ride with got a 2012 SST Team LTD and loves it. The problems might just be with the Altamiras (and SL-1's - I ride with 3 different riders who each had to have their top of the line SL-1's replaced under warranty).
