Ouch! Aluminum frame and rigid fork?
Perhaps aluminum frames and forks have improved by leaps and bounds I dunno but I just think that thing would beat me to death off-road. In fact I'm having flashbacks to my previous rigid mountain bikes 15-20 years back, fattest tires I could find back then (2.2?) notwithstanding.
I LOVE the compliant ride on my steel-framed '89 Schwinn Voyageur, in fact I think I'd rather take IT down a dirt/gravel road than the rigid Mt. bikes I had.
JMHO,
Mike
