Grip Preparation
From Pvdwiki
Most bicycle grips are simply glued to the handlebars using grip cement. This is fine as long as the end is left exposed so that a delrin handlebar plug is allowed to protrude.
In seriously wet conditions, one of the best choices for grips are ODI Lock-On Grips. ODI Lock-On Grips require a few modifications.
