Westernbiker....if you on ocassion bend your bike over and scrub the acorn nuts, they can be replaced for about $3 + shipping....the feelers just last longer and are easier to replasce as apposed to trying to get whats left of the acorn nut out and or replace the foot peg........I have seen a foot peg fall off from being ground to nothing....these are cheaper...and of course very cool at night!!!
