Rampage Origin

Origin of Speed

Rampage Origin is a purebred race machine, distilled from nearly 50 years of mountain biking passion, relentless innovation, and a drive to perform.

A pure expression of speed, efficiency, and purpose.
This is the Origin of Speed.

Starting from

Who is this bike for?

For riders who crave explosive acceleration, climbing with efficiency, and demand razor-sharp handling on every trail. Built for those who ride fast, push limits, and never settle for average.

Born from a Champion’s Vision

Rampage Origin was developed in response to a call from 2x Marathon World Champion Leo Páez:

“I need the best hardtail bike to fight for the 2025 Marathon World Championship at the Grand Raid BCV in Switzerland.”

The result? A machine built purely for racing — and proven at the highest level.
Leo’s Rampage Origin build, weighing just 9.4 kg (with pedals, dropper post, and tire inserts), carried him to a 3rd place podium finish after 125 km and over 5,025 m of climbing. A great preview on the most important race of the season.
