5 mm Mod .8 28T pinion?
 

For use with my Gen3 Robinson Racing slipper unit I need a 5 mm Mod .8 28T (and/or 30T) pinion. Does RCM carry that size?

26t is the largest mod.8 pinion we offer at the moment. :)

Thank you for your very fast reply. :smile:

'Was afraid of that. Need a couple of more teeth to get a bit more speed. This is with 26T pinion - would like to be around ~65 km/h:

It's for this new truck I just completed:

No way to use a smaller spur??

Nope, not with the current setup.

Just sent you an email. I'd like to order the 26T pinion. :yes:
