What is the weight difference between the carbon and aluminum frames for a Stumpjumper FSR or EVO for 2012 or 2013? I read that the difference for the Stumpjumper HT was ~6oz, if that is the case for the FSR or EVO I will use my $1000 elsewhere I understand there are also differences in rigidity and crash resistance.
2012
Stumpjumper S-Works 29er in Large is 25lbs 12oz
regular Stumpjumper 29er is 28lbs 14oz (Large, left) and 28lbs 4oz (Small)
26″ Stumpjumper comes in at 26lbs 11oz for medium (left) and 27lbs 5oz for XL
large sized 2013 Stumjumper FSR Expert Carbon 29 weighed 28.6 pounds with XTR 970 pedals
After seeing the weight difference in the Demo frame is only 12oz that would put the Stumpjumper's weight loss due to carbon from 6oz to 12oz, its probably around 8oz, not worth the $1100 increase in price IMO, especially without already fully upgrading all dynamic components first (wheels, cassette, cranks, brakes, and suspension).
Specialized carbon frames are .7-.9 lbs lighter, but they are also stiffer and have a better ride quality IMO so you are paying for more than weight. But either way, you are paying.
