Aaron Gwin putting the new Carbon Trek Session to work during a rainy practice day at Mt St Anne. No specs on the bike. Likely about 35 lbs with that ti spring and other light weight tricks that Monkey has been known to pull keep weight down. Now gossip amongst yourselves with speculation...
For the same weight, carbon has always been stronger than aluminum. Going to carbon is actually the right solution for a race-weight DH frame. Developments in fiber engineering are giving it an even bigger lead over aluminum and have solved the rock impact issues to the extent that aluminum has. Only problem, as always...$$$
Honestly, as in... Do you not pay any attention to technology and the huge difference between the production techniques and final strength of well made carbon fibre versus aluminum of the2009 Sessions, or are you just hating because thats what you do best?
I'm saying that I don't think that Trek carbon technology has come far enough to be used on a DH bike. I've been working at a Trek dealer for a few years now and I've seen how their carbon stuff holds up.
