You became a mountain biker the second you swung your leg over a bike. Your mtb is more than just a means to be fit; it's an accessory to your lifestyle. The REX 3.3 gives frames with 24mm axles a triple chainring option. Crank arms 100% CNC-machined from 7075 aluminum are combined with proprietary technologies to yield cranks with an exceptional stiffness-to-weight ratio that can handle any off-road thrashing you can give it. Together with ROTOR's Universal Bottom Bracket (UBB) system, the REX 3.3 offers a performance upgrade opportunity for all triple chainring mountain bikes with 24mm frame axles.
