Hope Technology has been working its “eternal crank project” for years. Not content with the conventional system of a tapered spindle to hold the crank arm in place, Hope engineers developed an expanding spline axle/arm interface intended to improve longevity and stiffness. Their use of Finite Element Analysis during development claims to ensure long-term durability and minimal weight – our sample weighed 587g with no chainring or bottom bracket versus Shimano M9000 XTR at 472g.
The 30mm axle works with Hope’s range of bottom brackets, enabling compatibility most standards. Axle options are available for downhill and fat bikes too. The splined mounting system accommodates direct mount chainrings, as well as traditional single or multi-ring setups via an adaptor. Tough and versatile, they should keep you going for years.
