DECATHLON ROCKRIDER XC 120 29ER 2026: Frame
The heart of the Rockrider XC 120 is the classic 6061 and 6013 triple-butted aluminum frame. The geometry is centered around 29-inch wheels, optimized for stability.
Geometry: Features a short chainstay to maintain reactivity.
Sizing: Availability is broad, but requires caution. The gap between sizes (S, M, L, XL) is significant; riders between sizes may struggle to find the ideal setup without swapping the stem.
Reliability: No critical failure points have been reported; the frame is designed to endure long-term stress.
