Xenon Racing 84 pitch prototype gears
Xenon Racing are currently testing new ultra-fine 84 pitch spur gears and pinions for the use with direct drive pan cars. With 64 pitch being tried and tested over decades the finer 84dp items will make for even higher efficiency and lower running noise. Prototypes of the gears will be in use at this year’s IFMAR Electric On-Road World Championships in the U.S. and it is understood that a decision whether the gears will make it into production or not will be made afterwards depending on the testing results.
