Using the same shape and form as the GP1, the GP1 BioKork utilizes the unique qualities of cork. Cork’s natural damping qualities make it an ideal grip material for urban riding, commuting, and leisure cycling. It is all a result of Ergon’s “GreenLab” initiative.
- 40% cork sourced from sustainable forests in Portugal.
- Inner core made of compressed grass fibers.
- Rubber palm section of the grip is vegetable oil based.
- German made rubber compound, latex free, UV stable.
- Right and Left specific grips.
- Forged 100% recyclable aluminum clamps.
- Available in 2 sizes.
- Available in 3 shifter styles/configurations.
- Off-road MTB use not recommended.
Offered in Small or Large, this is the thickness of the grip in hand. The Small and Large are the same length and have the same wing size. The only difference is the thickness of the grip in hand. Riders with smaller hands are best to choose the Small size. Riders with large hands are an ideal fit to the Large size. Ultimately, choice of size is a rider personal preference.
Standard: 2 full length grips
GripShift: 2 short grips
Nexus/Rohloff: 1 full length Left grip, 1 short Right grip
Ergonomic, great fit, locks securely to stay in place eliminating hand/wrist/arm fatigue. Cork looks cool!
Love them but this set I had to modify to slide all the way on. Shipping app shop was a failure.
I have just changed the 10-year old GP1 on my Brompton and the grips perform as expected. The feel is better for me than the original GP1; I like the combination of textures. I might add the new 2 finger GFK bars, if technically feasible. I recommend the grips highly.
So comfortable, and no more numb hands!
I first used these grips on my mountain bike and found the comfort and overall feeling to be wonderfully superior to the standard grips supplied with that bike. I decided to replace the grips on my commuter soon there after and have been really pleased with the difference in my hand and wrist comfort.
As for the installation, please follow the directions as they are correct. You can over tighten the Allen head bolts and strip out the aluminum part of the grips.
