Awesome product. I’m an older biker and have a cross-over (aka commuter) bike. My typical ride ranges between 10 and 25 miles, 3 to 4 times a week. Previously I used the Ergon GP-3 grips but found that my hands would begin to go numb after 10 miles. I switched to the GP-5L grips and behold, the numbness stopped. My best guess about why the numbness stopped might be because the grips offer a larger range of motion. I ride for a while using the major grip, then move my hands up onto the extensions, then up to the top, and back down. One benefit I didn’t expect is the leverage available when going up hills; gripping on the riser allows more leverage. Great Product if you have a commuter bike and go for longer rides.
