Rampage 428

Pure racing DNA takes fast to faster

The newest version of the race-proven and rider-approved Lee Cougan hardtail stands on the shoulders of a longstanding tradition of front suspension cross-country solutions. Making a fast frame faster in the case of the Rampage, universally lauded by nearly all those with experience riding or racing atop it, made for a difficult task indeed.

Design

Oversized downtube

The oversized downtube takes on a meticulously studied shape that, coupled with the oversize bottom bracket area and shorter, stiff chain stays makes for a structure capable of converting even the highest wattage pedal stroke into efficient forward movement.

Elbow design

Through the Elbow Design solution, we have managed to place the rear wheel inside the rear triangle, thus increasing the vertical flexion of the frame. The Rampage 428 gets its name from the short 428mm chainstay design made to keep the bikes handling snappy, reactive and more efficient.

What's hiding between the fibers?

While the Rampage is visibly different from its previous versions, the elements not visible by the naked eye represent perhaps some of the most significant advancements.

Internal cable routing system

While new shapes give a visual impact it is the absence of visible cables that makes this newest model somewhat disruptive. An oversized steer tube in addition to a specifically studied stem allows for the Rampage to route cables not only internally with regards to the frame but to hide them from sight by passing through the stem.

Lee Cougan’s Air Carbon Technology

Rampage model takes advantage of Lee Cougan’s Air Technology, a carbon molding technique that uses extremely high pressure in the molding phase to eliminate imperfections caused by trapped air in addition to blending the 1k, 3k, and unidirectional carbon fiber in a manner that makes for a more compact overall structure.

The result: stronger, more reliable carbon frames that weigh less than comparable frames that use more traditional construction methods.

3 Bolt Clamp System

The overall geometry sees an increased sloping design in order to allow for even the largest frame sizes to benefit from a shorter chain stay and its resulting compact geometry. The seatpost collar incorporates a great deal of new technology as it uses an advanced three bolt system that renders the seatpost and seat tube a semi complete unit, offering a feel and performance similar to an integrated design.
