FORM alloy
FRAME CONSTRUCTION:
FORM tubesets utilize premium materials to meet our strict requirements. Each FORM tube that we create is engineered for its specific purpose within the frame, ensuring optimized strength, weight, and ride quality.
RIDE-9 adjustment system
GEOMETRY:
The RIDE-9 adjustment system allows riders to quickly fine-tune their geometry and suspension with a pair of Allen keys. Nine configurations are possible thanks to two interlocking chips.
Adjust your RIDE-9 position for geometry before considering suspension effects, or variables like air pressure and shock compression. Make gradual, incremental changes, take notes, and be methodical. Don't adjust in a hurry before a big ride. Take your time and enjoy the process.
Smoothlink suspension
SUSPENSION:
Smoothlink suspension is efficient yet supple when you're on the pedals and across a wide range of gears. It features a controlled end-stroke and a rate-curve that feels more capable than the travel would suggest. This four-bar suspension design philosophy is centered on ride characteristics; each bike platform we develop balances variables like anti-squat, axle path, chain growth, rate curve, anti-rise, etc. to achieve the legendary Rocky Mountain ride feel.
