Details
Fishing for a great ride is easy with Trek's Marlin. Its super-light aluminum frame features the ideal geometry to deliver superior cornering, climbing, and descending. A set of go-fast knobbies keep you glued to the trail, and a 75mm-travel fork smooths the bumps, steering you through the roughest terrain. Plus, component highlights include a 21-speed Shimano drivetrain, a host of reliable Bontrager parts, and mechanical disc brakes that give you stopping power in all conditions.
Trek’s Smart Wheel Size
Smaller frame sizes are designed around 27.5-inch wheels, while medium and larger sizes are designed around 29-inch wheels. This ensures every rider gets the perfect combination of speed and handling, regardless of rider size.

Bought the bike pre Hurricane Harvey and rode it everywhere after the flood. I love the way it handles, easy shifting gears, rides smooth even through knee high water, muddy trails and water logged grass. Light enough to lift over a highway median or a fallen tree.
Comments:
I haven't ridden in a while and have gained a lot of weight, so I didn't feel my 26" trek fuel 80 would hold up........I'm not convinced 29" bikes are the way to go....I'm 5'6"" the handling sucks and peddling is a pain........just to be sure I replaced my rear shock on my 26"" to lock out shock it doesn't bottom out due to my weight and the peddling effort seems natural. Plus it is more responsive in the twisteys
