Excellent point about tires.
I had a look at your web site and found it very informative. I was wondering if you had compared a shift kitted 4g to an EZM direct drive. I read the EZM's aren't suited to shift kits but seem to be ok as they are. Any thoughts?
I've still got to do some more research into rear internal shifting hubs, as I hear some are better than others. Even if I don't run a shift kit I would still like the bike to be reasonable to pedal home if need be. I was surprised by the drag in my HT with the clutch fully in. Not fun just pedaling.
I also like the idea of sprocket adapters that bolt to the hubs in direct drive setups. Neat and simple.
