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.
When we first started building bikes it quickly became apparent that traditional frame geometry wasn't going to cut it on the steep descents and tight turning singletrack of southern British Columbia. To help tame this rugged landscape we developed ST3 Geometry - or Sloping Top Tube Technology. A sloping top tube means increased frame stiffness and strength, and when things aren't going so well, more stand over height for crucial dismounting ease.
The frame layout creates a compact front end, giving increased agility in tight turning singletrack while providing increased stiffness for greater control in all conditions. It's also bomber construction: with a greater separation between the top tube/seat tube and seat tube/seat stay welds, frame stress is distributed over a larger area of the seat tube. Originated by Rocky Mountain and copied by others, ST3 delivers a better handling, stronger frame - the ride of a lifetime.
