MECHANICALLY-FORMED 6061 ALLOY FRAME
Spyke 20 features a frame optimized for young riders. Trickle-down technology means that the new frame benefits from our leading platforms. The frame tubes are mechanically formed into complex shapes to increase strength and stiffness, minimizing weight and excess material use, resulting in a lighter weight frame and lighter complete bike.
SUSPENSION FORK
The lightly sprung Zoom 40mm Suspension fork is ample for smaller riders, smoothing out uneven terrain as well as improving grip adding loads to the fun factor on bumpy trails or jumps
