Ergon GMS Grips Review

The original Ergon GA3 grips were released in 2018, and since then, our team has collectively logged tens of thousands of miles on them. They’re the first thing I add to bikes I review, as I find the integrated mini-wing supports the wrist, reduces pressure in the palm, but isn’t too big to get in the way on singletrack. Beyond a properly fitting bike, I praise my arsenal of GA3 grips for my comfort on bikepacking trips and the lack of numbness in my fingers.

Six years ago, Ergon updated the GA3 with two size options: a small and large. I’ve swapped between both sizes and found the smaller-diameter grip better for technical mountain biking and the larger version more supportive on multi-day rides. At Sea Otter earlier this year, Neil and I got a sneak peek at the new GM-series grips, which consist of the new GMA grips (replacing the GA2) and the new GMS grips (replacing the popular GA3 grips). Ahead of today’s launch, Ergon sent us both sizes of the new GMS grips to try and to see just how different they are from the GA3.

GMS versus GA3

The change from my beloved GA3 to the new GMS grips is subtle. The biggest update is the redesigned mini-wing shape, which is smoother and more trapezoidal, with a more consistent outer profile. According to Ergon, the new shape better follows the hand’s natural form than its predecessor. The GMS maintains the same laser-etched clamp to assist with installation and is still available in Small (31mm) and Large (33mm) sizes.

What has always stood out to our team is how durable the GA3’s rubber compound is, and we’re pleased to see Ergon continue using the same rubber with the new GMS grips. Several of my Ergon GA3 grips have seen well over 3,000 kilometers and still have plenty of life left. The GMS grips use the same proprietary, UV-stable rubber that Ergon calls their GravityControl Rubber Compound. It’s soft yet supportive, with plenty of flex throughout the mini-wing and textured details for added grip and feel. Knowing it’s the same compound as the GA3, you can expect the new GMS grips to last season after season.

Both GMS sizes come in a fresh lineup of colors: Black, Chili Red, Juicy Orange, Slay Grey, Nightride Blue, Sage Green, and Lunar Lilac.

Thoughts While Riding

As you might expect, the GMS grips feel similar to the GA3s. However, I’ve used the GA3 more than any other grip, so I notice the subtle changes. First off, the mini-wing feels more supportive through my palm, with less of an “edge” where it transitions down toward the grip’s clamp end. I’ve occasionally experienced pressure points when shifting my hand too much into this transition area, and the GMS seems to alleviate that problem. On the narrow end of the grip, toward the clamp, the GMS appears to taper in less than the GA3, providing a less curved profile.

One subtle change is the updated grip finish. Ergon says the “Smart Texture Rhythm” dampens road vibrations through a precise pattern, but what stands out the most are the two horizontal raised ribs on the underside, which provide a mini shelf for my fingers to grip onto on technical terrain. It’s minimal, but it’s enough to feel more locked in and help keep my hand in the same position every time. It reminded me of the edge on the front of the SQlab 710 2.0 Grips I reviewed last year, which I’ve enjoyed on more technical terrain.

Overall, the GMS has a recognizable feel, and although the changes are subtle, they’ll be noticeable to anyone who’s ridden with the GA3 often. With a component as personal as grips, I can’t think of any glaring cons. If I wanted to get really picky, I’d say the internal lip at the plug-end of the grip that stops the grip from sliding on too far makes it hard to mount outer bar ends. However, I’ve gotten around this in the past by trimming the lip off with a razor blade. Problem solved. What I’d really like to see is an inner bar end that replaces the grip clamp, as SQLabs does. Ergon, are you listening?
