The Oury grip is made of Kraton-type rubber and has a soft supple feel. Something different about the Rider grip is that it tapers in thickness from the bar end to the center. There are small ridges at the inner end which help position your thumb. In the palm area, the grip has large square blocks, giving broad surface contact, while being able to compress away and give with a large shock. The Rider grip has deep square grooves between each of the rows of blocks permitting wire or zip tie fastening to the handlebar and water evacuation to the lower side of the grip so it will fall off. There is a flange at the outer end so the rider can blindly slide their hand to the bar end. The Oury Rider grips are a personal favorite and used by several of the people who work here. They weigh 102 grams per pair, have a durometer hardness of A/29, are 4.7 inches in length, and come Black, Blue, Grey, Lavender, Pink, Red, or Yellow. Made in USA. $ Price in Catalog
