Arrowmax MRX5 18T side pulley
Arrowmax have launched a full series of transmission belt gears for the Mugen MRX5 chassis. The pulleys are CNC-machined from 7075-T6 aluminium for highest precision and hard coated for maximum durability. Venting holes help to dissipate heat produced by the belts during running while they also keep the weight low for less rotating masses.
