Default prs

2/3 run PRS at our club. Mine has a plastic adapter that works but is quite leaves pinion at the very end of the shaft for good mesh.

Awaiting my PRs. Service to LHs is slow and direct has extortionate shipping.

I'm running 112/53 using the PRS adapter in my JRXS fir rubber tire with a 17.5. You'll probably want 112, 114 and 108 spurs and pinions from 46-53 to cover all your bases.

If you're running foam, adjust accordingly for rollout. In rubber I[m on 62mm diameter tires.

My rollout on 62mm rubber tires is 50.34mm with 112/53 gearing, on 58mm foams yo'd want a 108 spur with 54 or 55 pinion to get the same rollout. Ort a 106 spur with a 53 or 54 pinion.
