Hope aluminium crank now available
We're pleased to announce that Hope's long-awaited aluminium crank is now available from Chain Reaction Cycles.

After reporting here in September 2014 that Hope was going to have an aluminum crank, it seems they've spent a long time testing and retesting the cranks with their staff to make them the best they can be.

Here's a video of how they're made:

The finished product 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 the spline became worn once they’d been taken off and on a few times and with this wear and tear they’d suffer from the inevitable movement and annoying creak.

A unique expanding spline solved this problem. 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.

Added to this 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.

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 Hope’s expanded range of bottom brackets.
