Introducing the long-awaited carbon version of the incredibly popular, tried-and-tested EVO cranks. The EVO crank has been our best-selling crank, and we run them on our own bikes. The Carbon crank has been designed to maximise the advantages of carbon fibre, through a unique construction method, whilst using very small aluminium inserts to keep weight down. This, coupled with an optimised lay-up, ensures a good balance between ride feel, stiffness, and isolation from trail chatter.Longevity and serviceability are considered in everything Hope do, and the Carbon crank is no exception. With a 1K outer fabric used for enhanced abrasion resistance. The crank also features replaceable pedal threads, and similar to the EVO cranks, its axles and chainrings are interchangeable, making it compatible with most drivetrains and frames, covering you for the future.Much like the Hope HB916 and Carbon Bars, the Hope carbon crank was designed, tested and manufactured in Hope's Barnoldswick factory, showcasing their commitment to maintain the highest standards of carbon fibre production in the UK. Tuned stiffness characteristics for optimum ride feel. 1K weave outer fabric has greater abrasion resistance and gives the unique ‘Hope’ carbon aesthetic. Replaceable pedal thread inserts.
