Designed. Tested. Manufactured. Seven years in the making, the versatile, do-it all Hope Crank has finally hit the shelves.
You may have seen various versions of the cranks over the past few years on our staff and team bikes. We spent the time testing, tweaking and redesigning them to ensure they’re as good as they can be.
The final crank design features a unique expanding spline axle/arm interface (pat pending
). Previously, cranks with 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.
To solve this problem we settled on a unique expanding spline. The cranks are pulled onto a 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.
Added to this we 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. The spiders are available in either single (104 BCD) or double (64/104 BCD) ring configuration.
The cranks use a 30mm axle and are compatible with the majority of bottom bracket systems via our expanded range of bottom brackets.Specification:
