Carbon, full-sus, 27.5in wheels and narrower rubber, the Farley EX 9.8 blurs the mountain bike/fat bike lines - Russell Eich / Immediate Media
Full-suspension and fat tires are still a pretty rare pairing. The argument is that the big, mondo tires rolling single digit air pressures provide all the suspension you need.
The flip side to that argument is that full suspension allows some control to the cushion, thanks to a fork and shock's damping qualities.
Trek's full-suspension Farley EX 9.8 fat bike adds another twist to the conundrum, 27.5-inch wheels.

Dialed chassis
As you can see from the highlights list above, the Farley EX 9.8 is pretty dialed stock. The nearly all-black build with little red pops of color make it a very attractive bike in my eyes.
There's a country mile of standover thanks to the swoopy top tube and Trek's designers have done a commendable job at keeping the rear suspension tidy and flowing smoothly from the front end to the back.
With fat bikes looking like this, it's easy to say that the days of hobbled together mystery machines is over.

Blurring the lines
In addition to this being one of only a few full-sus fat bikes, the Farley EX is also in the rare camp of having 27.5-inch wheeled fattys.
Along with the bigger hoops there are slightly narrower tires, Bontrager's Hodags at 3.8-inches.
This makes me wonder if the Farley will feel more like a mountain bike with playful manners and less plodding.
It also leaves me questioning if the lack of footprint will leave it wanting when traction and floatation are paramount.
