That looks like one heck of a bike but I think I'll keep riding my '08. Maybe I've been lucky but I've never had any trouble with the rear shock. I do wish that they had never gone away from using Fox for their suspension but I've never felt cheated. I just think that switching suppliers may have been a step backwards for them.
I've got to wonder about all that travel on the front too. 140mm is a big fork. The new Enduro is now a 160mm single crown, all mountain bike. Is that where they're taking the Stumpy? I hope not.
