Joe Draperwrote a review of ESI Grips Racer's Edge Mountain Bike Grip on July 30, 2016
These grips are excellent. They're, cheap, light, attractive, and functional. I did find that on longer rides and races, these can cause minor numbness, but this was remedied by installing the chunky grips (which carry roughly 10 grams of extra bulk over the racer's edge.) Either way, these grips are the ONLY way to go. Absolutely amazing.
