Last summer I was riding with lock-on grips and was OK until it was time to put in some longer miles on my mountain bike. After only one long training ride, my hands were a wreck and I had painful blisters on my palms. My friend recommended ESI grips, so I went for it! I raced Park City Point to Point, a 78 mile mountain bike race with 90% on singletrack and 14,000' of climbing. I placed 5th in the Open Women's division and stood on the poduim with women that have raced for years and are nationally ranked. It was an awesome race, but best of all, my hands felt great! I've since raced and won 6 & 25 hours of Frog Hollow with happy hands! ESI Grips will never leave my bars again and not just because they are a 2011 sponsor, but because they have the best grips!
