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
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.
Overall, I'm happy with these grips, but I would caution users to follow the instructions about using a torque wrench, or at least be careful not to overtighten. Apparently, I did overtighten the Allen bolts, enough to cause wearing on the socket edges that made the bolts difficult to loosen and re-tighten. Fortunately, customer service was willing to accommodate my carelessness, and sent me a new pair of bolts in exchange for the user-damaged ones. Live and learn! Enjoy your new grips!
Great grips as expected. Much better than the stock grips that came on my ebike. Far more comfortable with the palm support than standard straight grips. Should have gotten them sooner.
The grips look and feel great ,and they stay in place Perfectly. The cork has a little cushion to it and the rubber has a bit of texture that Adds a nice touch as well.
