Hope Kids 68/73mm Crankset

Designed specifically for children’s bikes and their wee legs. Choose either 135mm or 150mm lengths. These cranks don’t include a spider or chainring.

Developed over many years the Hope crank has been designed using the latest FEA (Finite Element Analysis) tools and extensive multi discipline field testing.

The cranks feature a unique expanding spline axle/arm interface.

Previously, cranks using splines often used a taper to ensure a snug fit. These cranks worked fine the first time they were fitted to the axle, but once they’d been taken off and on a few times, the spline became worn, so they’d suffer from the inevitable movement and annoying creak. Hope felt there must be a better way. After many years of testing they think they’ve found it in the form of an expanding spline. The cranks are pulled onto a conventional spline, then a tapered plug is fitted inside the axle which can be tightened up each time the arm is refitted – giving a perfect fit every time.

Additionally Hope CNC machine the arms from forgings which gives them immense stiffness and strength. The arms also have a splined mounting for spiders and direct mount sprockets giving excellent versatility.
