Incredibly comfortable. Solved my ulnar nerve compression problems. I've heard a few people don't like being fixed at one wrist angle, but for me it keeps everything just right, and greatly enlarges the palm contact area. Not too heavy either. Caveats (1) I do road and XC so I can't speak to downhillers, and (2) unlike the GP3s I ran previously (but took off bc I didn't like the barends), the clamp on these crimped my thinwall XC carbon bars (despite Ergon's FAQ saying the non-barend GP1 is ok for carbon and despite using a torque wrench set at 5nm as indicated).
Have had a version of these on an all-purpose, hard front and tail, mtn bike for several years. Execellent accessory. Suggest pick the small (padding) version. It's the flat surface under the carpal tunnel that does the trick.
Significantly improves my hand/wrist position. I ride a long tail bike with lots of cargo and these far surpassed my expectations for what grips could accomplish for comfort and stability. I've had them on the bike for about a month.
I bought these in size small for my wife and I have very large hands but when I tune up her bike and ride it a little I do notice how great these grips are. I plan to buy the large for myself in the near future. I just need to decide between GP1 or GS1. I didn't think it would make that big of a difference but it really does. My wife has carpel tunnel syndrom and thorasic outlet syndrom and this helps a lot. Very very very good product and just fyi they have eco friendly packaging and are a good company.
