THE NEW GENERATION - Get Off on the series 4 Underworld trike with the all new Snake head gusseted frame including the new quick release adjustable seat slider. Commander V brake fork with 1 tool installation bearing caps, bladed fork legs and oversize fork crown. Wider, Lower, Longer because that’s what people wanted but we didn’t just stop there we added a more rigid 1 piece 15mm rear axle with sub frame and triad exclusive Sentinel rear platform. Revisions to the 49er wheels with bigger bearings for the new axle. A tough performing trike that represents great value for money.
