The RX crank is Hope's latest step into the world of Gravel and Road riding, following their successful RX4 calipers and RS4 hubs. A two-piece hollow design allows for the removal of any unwanted material increasing stiffness and reducing weight. This Gravel crank is manufactured to the same standards as Hope's MTB cranks, for confident use on or off road.
The Hope RX crankset is now featuring a self-extracting axle/arm interface to simplify fitting and removal as well as a versatile Spline mount to use Direct Mount chainrings or spiders. For a precise material removal, the crank arms are made of fully CNC-machined aluminium 7050 while the 30 mm axle consists of 7075 series aluminium.
Designed, tested and manufactured in Barnoldswick, UK.
