Just because they're your littlest racer doesn't mean they don't deserve a badass ride for their first race bike! The Position One Micro 18 is aimed fairly squarely at the youngest riders out on the track, the racer that's had enough of the balance bike and is ready for more speed and more air by pedalling. Close you eyes mum, these kids are ready to send it off the gate and the first jump and the Position One Micro 18 is built to handle the rough and tumble of the Under 5 sprocket class with an all aluminium frame and 100% CrMo forks ready for action. It's also nice and light, under 7kg! With the smaller 18 inch wheel and short 16.15 inch top tube, the Position One has been specifically designed by the same people that design and build the Chase range of race bikes to suit little racers by allowing them to get their feet on the ground, improving and building confidence as they transition to a bike with pedals. Other key components have been spec'd to increase durability and decrease maintenance. The alloy rims are double-walled which brings increased strength and the front and rear hubs are sealed to repel the dust from the track. 130mm Alloy three-piece cranks and smaller platform pedals all contribute to a package that has all the thoughtful touches of a bike suited for your youngest, and when they've outgrown it, because of the quality of construction, it'll be perfect for your next kid in line for the gate.
