True Dat !

Hand pump is only one issue of a tight grip.

The other is the killer,

If your welded to the bike the suspension cannot be set supple enough to give you control and traction..
Floating the grips is the ONLY way to let the bike move beneath you as it was designed.

A tight death grip contributes to sake bites,,,, err Pinch flats.. betcha didn't know that one !
