Product Description

The GR2 BioKork Grip is just like the GP1 BioKork except that it is terminated by a three finger composite bar end. The bar end offers up an additional hand position and more leverage for climbing out of the saddle. Instead of solid rubber, this grip uses natural cork, harvested from certified sustainable trees in Portugal for 40% of the cover. In addition, it also uses grass fiber for 40% of the grip core and vegetable oils instead of mineral oil in the gel palm insert. The benefits of cork's natural low density are a lightweight and comfortable gripErgon's patented wing-shaped grips support your hand and wrist in a way that relieves pressure on the Median and Ulnar nerves -- pressure that causes numbness, tingling, or pain. The shape of the GR2 BioKork Grip is a replica of Ergon's bestselling GP1 grip, and it's a great starting point for an exploration of Ergon's wares. By comparison, the GP1 shape is a bit more forgiving than the race-oriented GX1. So those looking for the most comfort, look no further. Each grip is held in place by a built-in clamp assembly on the bar end and set by a 4mm hex key. The angles of the grips and the bar ends can be adjusted separately, and when both are oriented to your preference, the clamp hardware should not be tightened in excess of 5nm.The Ergon GR2 BioKork Grip comes in two sizes -- 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 GR2 BioKork Grips are 54mm at their widest point (measured front to back) and are 132mm long. The left and right grips are mirror images of each other. They come with end ...

Ergon GP3 BioKork Grip Kork, S Review

I can't use the "racing" handlebars anymore, with a degenerative spinal neck issue that was probably caused by too many decades hunched over dropped bars. (I am 60)
Flat bars aren't a problem mtn biking when I am constantly moving around and on-off the bike, but for road riding they completely numb my hands in a couple miles. And with an 11 mile bike commute (each way) thats a problem.
I finally stumbled across Ergons when getting my new commuter bike. What a difference!
They definitely have a learning curve and are suprisingly finicky about their adjustments, with really no hints from the manufacturer on how to fine tune them.

I really like the shortie bar ends, once I finally figured out they are emulating the brake hoods on dropped bars, which is where most people ride dropped bars most of the time. You point them almost flat and hook your thumbs over them as you would brake hoods, which takes pressure off the ulnar nerve and gives some extra hand positions.

Fine tunning the angle on the bar ends and on the flat grip area, just a few degrees makes a *huge* difference. I thought the grips were a Fail, until I rotated the paddle a couple degrees closer to dead flat, and now they keep my fingers almost tingle free, and it will probably get better as I get used to moving around on them and getting the pressure points really fine tuned. Its very different from round grips.

Also going with a lower angle somewhat forces me to bend my elbows a tiny bit, which is more shock absorbing than straight arming the bars.

One thing no one seems to mention is the better control of the bike you get with these. Its a very stable platform for controlling the bike. And the nubby bar ends are perfect for climbing hills,really helping that.

I like the cork. It was happenstance that I got the cork version. I ended up with small, even though my hands are medium to large guy hands. The only difference in size is the diameter in the thumb area. I commute year round in the Northwest and I would not want a larger diameter since I wear long finger and heavier gloves almost year round.

Very easy install. I grease the threads on the bolt. (at your own risk) and barely tighten the bolt at all. This avoids shearing the bolt and locks it nicely into place.

Very finicky on adjustment and no hints on how to figure out how to fine tune them and its not quite a miracle difference, is the only reason not giving them 5 stars. I have to work at moving my hands around still, but I can get to work and still feel my hands now.
