Stumpjumper FSR or EVO frame weight difference carbon vs aluminum
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.
Thank you for any insight and information!
After some digging I found this:
Demo 8 Alloy frame 10lbs 13oz
Demo 8 Carbon frame 10lbs 1oz
2013 unknown sizes
Stumpjumper FSR Expert EVO carbon 29er 28lbs 8oz
Stumpjumper FSR Comp EVO alloy 29er 29lbs 10oz
Stumpjumper FSR Expert EVO carbon 26″ 27lbs 4oz
Stumpjumper FSR Comp EVO alloy 26″ 28lbs 10oz
Stumpjumper FSR Comp alloy 26″ 27lbs 15oz
Stumpjumper FSR Comp alloy 29er 29lbs 10oz
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).

Did you end up picking a bike? Does the Evo Carbon frame come with an alloy rear triangle?
randomly came across this, so let's bump this baby...
reportedly (specialized brand store employee), only s-works frames have carbon rears
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.
