It's kinda difficult to get the gears here in Malaysia... Wonder who's the distributor?

dave - what about smaller than 72t spurs? I think there is an opportunity there with 1/12 1s.

hanulec,
That may be a size in the future. Can you prove to me that you can't get the same, or very close, rollout with a 74t spur?

Dave,

I dont think it is a ratio thing as much as a space issue. With a 76/54 it is getting more difficult to tighten the top motor screw because the pinion is larger than what we use to run. If we could get 72 or even 70 spurs we could run smaller pinions and be able to adjust the motor....

How come I can run an 88t spur with a 59t pinion and adjust it just fine on my Shock Wave????????????????

Using a 2mm screw rather than a 2.5 mm (as I prefer) allows you to get to the motor screws a little more easily.

I'm running the competition's Spur gears on the VELODROME on a pan car

I generally run a 72t or 73t 64p spur with anywhere from a 62 - 65t pinion.

I was really hoping we could get Jay to go smaller than 76. But I'm glad to see NEW stuff coming!

I've been Geared by KIMBROUGH for 25 years!!
