Re: What do you think about these as handlebar grips?
Comfortable grips are really important if you have arthritis or other hand issues. My difficulties are a combination of early stage arthritis and nerve damage from being struck by lightning sixteen years ago resulting in Guillane Barre Syndrome (like polio). I've tried a number of different grips and in the end my favorite is a set of foam grips which I then cover in hand stitched elk hide. Very comfortable for me even for long rides.
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
