The German engineers at Ergon are pushing the envelope with their GreenLab initiative, utilizing the natural damping qualities of cork as a grip. The Ergon GP1 BioKork Grip uses cork from deep in the forests of Portugal as a hypoallergenic, ecologically sound material. The inner core is reinforced with natural fiber and uses a vegetable oil base as opposed to a mineral oil base in the gel in the palm of the grip.
Ergon's GP1 grips sport a wide, ergonomic shape to accommodate more of your hand. The supportive shape helps reduce numbness and fatigue during long or bumpy rides. The alloy clamp helps secure the grip to the handlebar, no more messy glues or sprays to deal with.

It is really a matter of individual biomechanical preference, but that said, I now have come to absolutely insist on the "platform" grip i.e. ergon design as opposed to any sort of round grip - however padded or textured such a grip may be. (on my three hardtails I have each of ergon's models, size & materials differ) I find the platform far more comfortable and also more biomechanically efficient in as much as the broader grip actually provides more leverage for torque along the axis of the bar. Installation is perfectly easy, the cork per se is a very pleasant feeling material. Only possible caveat is can be a bit finicky as far as getting them tight enough but not so much as to harm the mechanism or crunch one's carbon bar
Summed up: simply would not be without ergon grips
Yes, I would recomend this to a friend.

I've ridden these quite a bit over the past month - once they are set up correctly, they work really well. Just be prepared to tweak their position a bit on your first few rides.
I also tightened them a bit more than Ergon recommends. They tell you to go with 5nm, but I had a little slippage so now I'm tightening them to 6Nm...I also use aluminum bars so I am not to worried about damage from the extra torque.
These are definitely grips I'd recommend.

Love the look of these grips on my Necro Pugsley. Also have a brown Brooks saddle so it "Ties the room together." Easy to get on and adjust. I've tried Ergon's in the past and have since went back to larger round grips for most of my bikes. Giving these another go. Rode 2x so far and don't really see any sort of "bio-mechanical" benefit. Maybe after like 20 miles or so you would see something, but in 10 -15 miles, not so much. Decent enough price to try. The end caps suck. They bust into pieces when you try to plug your bars.
These went on super easy, and stay super snug with no muss and fuss. I had no issues with the endcaps, not sure where people can have problems. My wife loves them, and they are very comfortable for her. Treefort, by the way, is AWESOME because I inadvertently ordered the large size, called, bought the small and they got to me super fast and the large got sent back and refunded to my credit card. The refund took quite a few days to process, but that is a credit card company hard not at work. Treefort is definitely one of the better online retailers, buy with confidence!

Using them on a Brompton S-bar for daily commuting (13mile round trip). Very comfortable and massive improvement over any traditional shaped grips. Only minus were the handle bar plugs which due to their odly square shape ended up being slightly off center. Without the plug issue would have been a 5 star.
Still slips at 5nm on my carbon bars, I didn't want to go tighter so I put a bit of rubber cement on them.
What carbon clamp?
The cheap end plugs are impossible to install with out breaking they are like a cheap brittle plastic, I emailed ergon support twice about this problem 3 weeks ago and they still have not replied.
To put the bike on my truck I have to take the front wheel off even though I'm careful with the bike upside down the cork has broke off in small chunks.
