Hope Technology is based in Lancashire, North UK and operates a 24-hour facility to produce premium quality CNC machined and anodised bike parts. Their top-notch products range from hydraulic disc brakes, hubs and wheels, stems and cranks to high output lights, and much more. The precision and tolerance of their products guarantees the highest performance and longevity.
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.
