RIDE-9 adjustment system
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 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.
