Well.Surviving Tucson's terrain shows that this one is trail capable, but it's a little more cross country than what is quickly becoming the norm.
I have to pity people who never can ride trails on anything steeper than 66 HA and 6" travel. Especially since everyone at TeeGeeAre, spankmonkey, BridalMTB tells us that mountain biking has "progressed" and actual trails that were not built to "flow" (BMX track emulation) standards are not "modern" and any fool jamoke can ride a "flow" trail on a road bike!
The evolution of BridalMTB to fast twin of fapBlister Queer's Review, in which image is sold before substance, has been a wonder to witness.
So to translate: if you don't know how to ride a bike, then the Norco Optic Carbon 29 will not make you feel like a winner when you encounter any trail outside the modern "flow" paradigm. You'll actually have to know how to ride a bike in varied terrain, and the good clowns at BridalMTB will do their damnedest to lobby for more modern "flow" trail conversion of all existing trails everywhere.

The latter means: yeah, I pass MTBs on descents, even "enduro" bikes. Because the "modern" enthusiast doesn't have any skill, he just has The Bike to Kill All Bikes.
