This thread talks about the hardened steel pinions and Mike's view on them. I'm thinking that a slipper would go a long way to make those pinions wear better since there would be some give with some form of slipper.
I'm not sure about the potential heat issue. Nitros use the clutch a lot harder since it slips most at low rpm. The heat is caused by the rubbing surfaces when there is slippage. As long as the hub and CB spin at the same rate, there is no slipping, therefore no heat.
I wonder what Mike's take is on all this? I'd be curious as to what he thinks.
