FORM


The heart of a bike is its frame. The geometry, the material, the feel, and the way it reacts under the rider are the very essence of the ride. That’s why we’ve introduced FORM™ – the design and manufacturing process of our high-performance frame tubing. Our philosophy behind FORM™ tubing is to push the limits of tube and frame design to create the frame’s unique riding feel.

Engineered Ride Quality: FORM™ tubing is a line of high-performance tubes designed to elevate the superior ride quality for which Rocky Mountain Bicycles are known. Innovative design: With 25 years of innovation, we continue to push the boundaries of bicycle design. FORM™ tubing is the exciting new frontier of our creativity.

Attention to detail: Every detail in a FORM™ tube set is carefully engineered and has a purpose: from the slightest variations in shape, to wall thickness, tapers, flares and bends.

Uncompromised quality: FORM™ tube sets are manufactured with premium materials and delivered by the best suppliers in the industry to meet Rocky Mountain’s strict requirements.

STRAIGHT UP


We’ve got your back. With a first of its kind 76-degree seat angle, you’re in a position to defy gravity at every technical uphill climb. The Straight up geometry and its bio-mechanically correct seat position allows for maximum horsepower. Not only will you get an efficient ride, it’ll save your lower back and limits pressure on your “sensitive areas”... if you catch our drift.

SmoothLink Suspension


Our groundbreaking SmoothLink suspension features minimal pedal feedback so you get a smoother pedal stroke, especially on uphill climbs. How does it work? By placing the rear pivot above the rear hub axle, we keep the average chain torque line parallel to lower link (the line between main pivot and rear pivot), we eliminate pedal bob.
