Question: will these work with a twist shifter?
Document: I can ride hours without gloves and not get numb hands. Easy to install and can be adjusted to suit hands. Comes in two sizes and accommodates small or large hands. These grips really work and look classic too!
these work very well for long rides, or intense rides. they spread out the weight on your palm so it takes longer to get uncomfortable. i have rode for 4hrs through very technical terrain and they caused me no problems. they fill the hand too, also the end cap is durable. i have wacked it on many trees and rocks and they still are in the correct position and have only cosmetic scratches.
No problem if you are used to shop work, but probably a big problem for those with no shop and no tools.I have large hands, and I ordered the large size grips. These are probably a better fit for me than the small size, although they are pretty bulky. It seems many others purchase these grips because of problems with numb hands and fingers. The shape of these grips allow us to put our upper body weight on the strong, heel section of our hands, particulary on downhill sections.
this is not exactly what you think,-quality control is not perfect, the cork came already frayed at the ends of the grips, and the threads had not been cleared, leaving sharp burrs to get cut on if you don't notice them and remove them.- Cork? when they say cork it makes you think the grips are made of cork, but they are actually made of a clear rubber with small peaces of cork suspended inside.
they don't even come close to fitting! also bar end plugs are not as shown, they are an organic black plastic with gray symbol.- extrusion plugs left on the black rubber part of the grip.all in allgreat grips, make the ride very nice and comfortable, but the craftsmanship is not all that the other views state. and the bar end plugs are worthless.
these were a gift to my son , and he totally loves the feel of these grips when he rides . He says they reduce the numbness in his hands after a long  bikeride . A total hit
i love this the moment i saw the grip... it stand out as the holy grail of grips... being a natural material that is produce with green process and sustainable....Using the grip is relaxing and seeing it is floating with coolness the way you put a cork in the water... slowly afloat....I recommend this cool grip nothing more nothing less... try it and you will know
Well, not from Amazon but from my regular supplier of bike bits.They are just awesome. Super comfortable.Took my bike into a major bike store recently while I went to get something and the guys in the store wanted to know all about them. I think they're going to start stocking them!
We are used to ad photos that make products look better than they really are, but these cork grips look as good on the bike as they look in ad photos. The instructions caution against cleaning the cork with anything other than soap and water to keep the fine appearance new looking. I don't know what effect various solvents and cleaners might have on cork, but I don't want to find out.
Very comfortable, new, handle-bar grips. I am very pleased with this product. The cork is very cool, comfortable, and giving. I would definitely try more from this brand and seller
