The natural moisture of my sweaty palms as I hold
the wheel in the grip of death after I have outbraked
the motorcycles into the turn, passed the Corvettes
on the outside, and accelerated out of the turn,
serve to prevent slippage on a polished Nardi wooden wheel.-Bob
If you want grip, get the plain slip-on fake leather
cover with the notches all the way around the outside.
It seems to give you more leverage, too.
