If you are looking for control, performance, and value in your new mountain bike, the Masso is sure to please. With amazing features, such as a premium XLS crankset, 650b+ wheels, and the versatility to use 29er wheels, this bike performs great and is ultra versatile. We live in the Rocky Mountains and demand performance, fun, and durability from our mountain bikes. For this reason, we created our best and most durable MTB frame ever, which is covered by our incredible lifetime warranty.

 

 

Frame

The Tommaso 650B+ (27.5") Alloy MTB thru-axle frame is rack ready for all your bikepacking and commuting needs, while XCM thru-axle fork offers 100mm of travel to crush your local trails.

 

Drivetrain

Once you ditch the front derailleur and go 1x, you don’t go back. With a huge cassette in the rear, the Masso offers 10 quick shifting speeds with a wide 11-42T range. The clutch rear derailleur also keeps the chain tight to avoid bouncing during your descent. After you try this drivetrain, you’ll wonder why you ever used a front derailleur on a mountain bike!

 

Brakes

Power and speed is nothing without control. This is exactly why we equipped the Masso with Shimano Hydraulic disc brakes, for precision control and excellent stopping power. These powerful brakes allows you to ride with confidence, knowing that you have quick stopping power to descend even the steepest mountain.
