We wanted to craft a 1x crank for mtb frames with 24mm axles that could be matched with our Q-Rings (or noQX rings – your choice) for optimum pedaling efficiency with a single chainring setup. Crank arms CNC-machined from 7075 aluminum are combined with proprietary technologies to yield cranks with an exceptional stiffness-to-weight ratio that can handle an off-road thrashing. The REX 3 offers a performance upgrade opportunity for all mountain bike with a 24mm axel.
