REI Co-op Cycles DRT 4.1 Fat Bike

Note: As of mid-November 2021, REI did not have any DRT 4.1 fat bikes in stock. However, several other DRT models are available here, many sporting similar features. Check back with REI, as inventory is frequently replenished.

 

In winter 2021, I had a blast riding the REI Co-op Cycles DRT 4.1 Fat Tire bike at the Grafton Trails & Outdoor Center in Grafton, Vermont. The Center, which also caters to crosscountry skiers and snowshoers, features 15 miles of hard-packed groomed trails and rugged single track that cover a variety of terrain, including woods, hills, bumps, straightaways, and even a covered bridge! The DRT 4.1 handled it all with ease.

Testing the REI Co-op DRT 4.1.

As you would expect from a company like REI, this bike is well built, and features top-end Shimano hydraulic disc brakes and a 1×12 drivetrain with SRAM X1 1000 Eagle crankset and SRAM SX Eagle 12-speed rear derailleur. The low-profile crankset gear virtually eliminates the potential for snagging on logs, rocks, and pant legs.

The bike is remarkably light, too, thanks to its rigid aluminum frame and lack of a suspension system. At 39 pounds, it’s extremely easy to maneuver and transport, whether you’re loading it into the bed of a truck or on a bike rack.

The DRT 4.1 comes with 26” wheels and super-grippy Inova tires that made it easy to negotiate the Center’s groomed trails, even on steep hills, and also provided a level of cushioning on the bumpy single-track trails through the woods.
