Almost there. Just short of full-sized, the Haro Race Lite Expert XL features a 20" top tube length with room to move. Lightweight aluminum construction with a sturdy chromoly fork to handle the hard landings of the learning curve. The parts are size-matched to fit the slightly longer frame with 170mm 2-piece alloy cranks and instead of the narrower "Mini" sized wheels and tires of the smaller bikes in the lineup, the Expert XL features 20 X 1.5" alloy rims with a 1.65" front and 1.5" rear tire for more surface contact to put the power to the ground. A rear disc brake slows your roll when you've crossed the finish line. FEATURES 6061-T6 heat-treated aluminum frame with integrated head tube.
