SMALL SIZE, BIG FUN
The Siskiu T27 carries the same do-it-all trail spirit as the regular Siskiu T, but is purpose-built for smaller and younger riders. Its lightweight alloy frame, 140 mm of rear travel, and 27.5″ wheels deliver an agile yet stable ride, while shorter 165 mm crank arms and a 100 mm dropper post ensure comfort, control, and a dialed fit for compact riders.
ULTIMATE VALUE
Built for riders stepping up to full-suspension performance: the ALX Trail frame with One-Piece Linkage delivers smooth, efficient travel paired with a RockShox Recon Silver RL fork and X-Fusion O2 Pro R shock. Shimano CUES 10-speed shifting, hydraulic brakes, and a TranzX dropper post complete a trail-ready build that hits the perfect balance of capability and value.
