Size Specific Tune
Size Specific Tune ensures that riders of all sizes get the right balance of small-bump compliance, mid-stroke support, and end-stroke progressiveness. Our design team does custom shock tunes based on real-world field testing and adjusts each tune for specific frame sizes. The new Altitude also has size-specific chainstay lengths to offer a balanced ride across all frame sizes.
FORM™ Alloy
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.
