GS1 Evo

When used on a Brompton, these are a nice incremental improvement over bike-standard, adding comfort & support while remaining compatible with folding action.

But, be sure to check whether they will work on your bike configuration. It turned out that they do NOT work on a P-line 12-speed mid-height bar. The combination of bar geometry plus the extra shifter ring used for the 4-speed shifter on the left handlebar means there is insufficient room on the handlebar to use these grips. So, take off your factory grip, check the available handlebar, (move the shifter/brake if you need to as far as is properly available), and measure before ordering.

I note that I sent in a support request asking the company if they had checked compatibility, and I got back a pretty cold response simply saying "They work on bars with ... available space". It was a bit off-putting. Nowhere on the product page does it indicate the amount of handlebar required. Seems like this would be important to put there.

(Fortunately, I also have in the household a flat-bar Brompton, and these grips worked on that, since I can move the shifter further inboard on the flat bars.)

I came across Ergon grips while scrolling FB and thought they looked promising, so I tried them out.
They are exactly as described, very comfortable for my old man's hands, and attach securely to my bike, which most grips don't. These don't spin around the handlebar with abandon like every other grip I've tried.
Wish they'd offer some that would fit my e-bike with a grip throttle. I'd switch to them in a second.

This is definitely one of the best grips that Ergon has ever made. The revised shape combined with the new rubber just makes it more comfortable. It also gives you better feel at the bar than the old GS series. Would definitely recommend!

These are the most comfortable grips you will ever find for very long days on the mountain bike. Great support without compromising control for difficult off road riding.

I absolutely love them. They have helped my hand numbness a lot. Very comfortable.
