Description
Designed specifically for ambitious young shredders (ages 7–11), the Polygon Siskiu D24 Evo Frameset delivers full-suspension trail performance built to scale with growing riders. Crafted from lightweight ALX 6061 hydroformed aluminum, this chassis provides 120mm of rear wheel travel and features a versatile mullet-compatible design (allows upgrading from a 24" front wheel setup to a 26" front wheel for extended usability). Engineered with internal routing for both gear and dropper cables, a tapered headtube, and a modern 12x142mm rear thru-axle, this frame offers a durable, high-performance platform for progression on rocks, roots, and jumps.
