I have a hard time working out exactly how TheGrip works. Is the head covered with one of those condom style pieces? I would have thought that would have helped limit blister potential. Also, what level of Hg is required?
I’m half tempted to buy one, but the general idea I get from what I’ve read is that it works great when new, but the parts wear out and after sales service is pants.
Bike2swim, What results did you see in those 9 months?
