Specialized Fuse Pro 6Fattie 27.5+
You've probably heard about the 27.5 mountain bike wheel size that has fast become a rival in popularity to the 29'er. The bike industry is in the midst of an intense period of mountain bike innovation and the latest technology to emerge is what are being called 27.5+ bikes, which are built to accommodate wider tires than traditional mountain bikes can.
The Specialized Fuse is an aluminum hardtail that comes equipped with three-inch wide tires. A diamond-shaped cut-out in the chainstay provides extra clearance for the tires and helps shed dirt and mud. Though the wider tires mean more rotational weight, they also offer more traction. The main argument in favor of 27.5+ bikes is that they are just more fun to ride. They corner, they stop, they roll over obstacles. In short, the 27.5+ bikes are a more nimble version of the grin-inducing fat bikes (with four- to five-inch wide tires) that have stoked scores of riders over the past few years.
Specialized uses SRAM 1x11 for the Fuse and the bike includes the new wider rear axel standard, known as Boost 148, to accommodate the Fuse's extra-wide tires. Tubeless tires invite low tire pressures for still more traction, while a Rockshox Reba handles suspension duties up front. Disc brakes with 180mm rotors provide the Fuse with plenty of stopping power and internally routed cables give the bike a clean look overall. [$TBD; specialized.com]
