Mammoth – Shimano Di2 12 Speed

Description

The shorter-travel trail bike built to climb efficiently, descend with confidence, and keep you fresh for long days on the trail.

The Mammoth is our downcountry trail bike for riders who want long-ride efficiency without giving up confident handling on the descent. Designed for big trail days on routes like Buffalo Creek and the 401 in Crested Butte, it delivers the climbing traction, stability, and plush ride quality needed for technical terrain and fast, demanding miles.

Overview

If you want a bike that feels fast on the climb, controlled on the descent, and comfortable deep into the ride, the Mammoth is built for that balance. It shares the sure-footed character of the Behemoth, but with 110mm of rear travel and 120–140mm of front travel for lower weight and greater efficiency when longer travel is not necessary.

The result is a trail bike that handles long, steep climbs with traction and composure, then rewards you with stability and control when the trail turns rough or speed picks up. On slow technical sections, the Mammoth stays precise and maneuverable. On faster descents, it gives you a more planted, in-control feel that encourages you to ride farther and faster.

Ride feel

The Mammoth is made for riders who want trail-bike capability without unnecessary travel. Its progressive spring curve gives the rear suspension a super supple feel over small bumps, while preserving the support and stability that matter when you are putting power down. That means less trail chatter, fewer pedal strikes, and more confidence when you are climbing, cornering, and descending.

It is a bike that feels composed in technical terrain, responsive in tight sections, and impressively stable when speed increases. For riders who want to stay efficient without sacrificing ride quality, the Mammoth hits a sweet spot.
