Description

The Lenz Sport Mammoth is setting a new standard for endurance racing and cross country trail bikes. Until now, a lightweight 5 inch travel cross country bike was unheard of. This Lenz bike takes the famous XC geometry of the Leviathan and sets it on a 5 inch travel rear suspension system that uses a 2.5:1 leverage ratio. The Mammoth climbs like no other 5″ travel 29er you’ve ever ridden, and it descends smooth and stable even in very technical terrain. With the big wheels, stiff frame, and complete bikes as light as 25 pounds, the Lenz Mammoth will surely be on the wish list of every cross country trail rider and endurance racer.

The Behemoth Plus is an awesome ride. It crawls up steep ascents, bombs down rocky descents, feels stable and in control on slow technical moves, and eats up rocks for dinner. You [...]
