The Ergon GP1 grip is a great starting point for an exploration of Ergon's wares. The grip has two kinds of rubber, a harder rubber on the outside and a soft, patterned and textured Kraton rubber pad that both grips the hand or glove and offers great support. Each grip is held in place by a forged aluminum alloy clamp set by an Allen key. By comparison, the GP1 is a bit more forgiving than the race-oriented GX1. So those looking for the most comfort, look no further.
Since the grip is a unique shape, the wing shaped support is right where some glove makers are putting extra padding these days and provides more support for the palm of the hand. It's great that the clamp is what holds it in place. This way, the grip can be slid on and the clamp left loose so a rider can get a feel for where the ideal position is. Most likely, people will have it at level or slightly below level, but having a clamp so the grip can be set and reset until the position is dialed is a sweet convenience. Those who do drop-offs or spend lots of time with their butt behind their saddle might want the grips lower still.
The Ergon GP1 grip comes in six versions -- standard, SRAM, and Nexus/Rohloff widths in small and large. The size does not refer to the length but the thickness of the grip. The people at Ergon tell us that macho types assume they should have large unless otherwise indicated, so consider this a warning. Ergon has found that most people, except those who have huge mitts, go with the small. The smaller diameter is lighter, a bit stiffer, and easy to grab. Those with big hands and those who spend long, long days in the saddle might want to lean towards large.
The grip is 54mm at its widest (measured front to back). The GP1 Standard small and large are both 140mm. The GP1 SRAM small and large are both 94.5mm long. The Nexus/ Rohloff set has a full length left side grip and the right grip is 96.5mm long to accommodate the twist shifter. The clamp tightens via a 4mm Allen key and is designed to take not more than 7nm of torque. The left and right grips are mirror images of each other. They come with end plugs and mounting instructions. Weights for the GP1 are 169g per pair for the standard small, 206g for the standard large, and 155g for the SRAM small, and 174 for the SRAM large. Available in Black/Grey. Those of you using the Nexus-Rolhoff system, please be sure to make the appropriate selection.

I've had carpol tunnel of the wrist so standard grips just don't work for me. Odi's and the like, while they look great, kill my wrists and forearms after a long and arduous climb/descent. I wish I could use them but I can't. I used to use Specialized BG grips on all my bikes but after awhile the wide part of the grip that supports your weight leaning forward started to become too flexy and there was no gritty tactile feel for the extra "hold on for dear life" death-grip on the gnarly DH sessions. I have both the Ergon GR2 on my On One 456 Summer Season and GP1 (on my Trek Fuel Ex) grips - - my most recent Huck N Roll purchase, btw, and they NOTICEABLY add so much comfort to my ride. Well constructed and quality material. Ergon has grips with or without the bar ends. Both are equally comfy. The bar ends just give you more options as far as hand position when climbing.
As I began my foray into replacing my 10 year old bike, I rode friend's new bikes. A couple had these grips, and I did not buy the bikes they had - but I went with this grip (which they had). I don't have carpal tunnel, but I have had numbness and tingling issues with a conventional grip. These seem to solve that problem, and I just find them to be very comfortable. From the reviews, this product falls into the category of personal preference (ie it is not just a good or bad product - it will vary depending on all kinds of factors), but if they work for you, you will be psyched. I like them and am glad I chose them for the new ride.
These were the first Ergon grips I tried. I do in fact have pretty large hands. I wear XL and even XXL gloves, so I tried the large size grips. They were fine riding on flat, open bike paths etc, but riding on single track trails, I felt like I was wearing mittens or something. I don't think it really matters how big your hands are, these just are not designed with bike handling in mind. If you intend any off road, technical use, try a different model like the GS1 or GX1. If you just plan on cruising around the neighborhood and such, these will be fine.
I bought these because i was having a lot of trouble with my standard grips... On the descent i had tons of pressure in the "pit"of my hand, between my thumb and index finger. After long descents my hands were killing me. Talked to several bike techs here at BC and they recommended me to get Ergon grips. This way it helps disperse the the pressure across the majority of my hand vs. just the pit between the thumb and index finger.
These grip lock so solid on the bars it inspires confidence. But, the best part is my fingers don't go numb on long DH runs, and I can keep my hand strength for 7-9 hours now. Instead of most of my weight carried in the thumb crotch, it's now spread over the whole palm, which also means my steering control is now on the outside of the bars where there's more leverage.
I'd never even think about going back to tube-shaped grips.
I had these installed on my 29er for a while but ended up installing them on my commuter. Like others have said, they are ok for a little while on a mtn bike but I feel like sometimes you need a traditional grip that you can wrap your fingers around. I think it really depends on your riding style and the trails that you choose.
I ordered these but had to return since the grips were not black as the picture indicates. The grip area is a dark grey and palm area light grey with the clamps being silver aluminum. Otherwise, I tried these grips on another bike and loved the way they felt, especially after a long ride.
The sizing doesn't reflect the width or clamp size, but rather the "girth" of the grip as you hold on. Unless you have HUG-UNGOUS hands, you're gonna want the small.
Great grips. Comfortable when chattering along rocky downhill runs, but they also provide lots of decent hand positions for climbing.
very comfortable and easy to install... i use my bike on trail and to commute around town and these just make riding for long periods of time enjoyable
The grip pictured is the low weight plastic clamp grip. The grip received was the heavier, metal clamp grip. Still functional and it is very comfortable.
I tried to like these. I really did. I built up a rigid 29er and put these on because I hoped they would save my palms and wrists some wear and tear. And they did...at first. They lock your wrists into a particular position and are great on climbs. They spread out the impact on your palms and for a while make descending better on a rigid. Once you get them dialed angle-wise in they seem much more comfortable than regular grips. They're firm yet squishy and nice and tacky and grippy.
After a long descent, though, it just became painful, because it's harder to hang on to these. That wing on the back is right where I would be gripping with end end joint my last three fingers, so instead of allowing my really wrap my fingers around the bar if forces me to crimp on a larger surface. After long descents or on really long rides this just pumps out my forearms and causes everything below my elbow to turn to painful jelly. It's also a pain when climbing out of the saddle, because your wrists rotate forward and it's harder to grab the bar. I thought it was because my fingers weren't in shape; I built up to longer rides and even did the Tahoe Sierra 100 on these (not to mention the rock climbing I do). In the end my hands just never adjusted and my forearms were always painfully pumped out after long rides with anything technical or bumpy.
I have pretty big hands, that may be my problem (I tried both the S and L; the L was just humongous and the S worked better). I know some people swear by these things and love them, and I know people like me who tried to like them and just couldn't get into it. Eventually I went back to ODI Rogues and have been much happier since, they're just so much easier to hold onto. I think it depends on your hand size and shape combined with riding setup and style. You may love them, you may hate them. I also tried the GX1 grips because the wing is thinner, but had the same problem there. These are squishier than the GX1 and a little tackier.
As far as quality goes, they are built well. I wish there were a clamp on the inside as well for more peace of mind on carbon bars, but the outside clamp holds reasonably well. They wear at a reasonable rate, though a little faster than the GX1. I had no problems with quality at all.
