The suspension system employed on the All Track Trail 20 & 24 is a classic single pivot swingarm. This provides ample suspension travel for junior models and reduced weight. Fewer frame members means lighter weight, which is especially important for small children. The other important benefit is simplicity and durability, as few moving parts possible for being trouble-free for the long-term. This translates to a junior full suspension bike light enough to be nimble and efficient pedaling, yet confidence inspiring when blasting downhill.
