The Good: Thick N' Sticky
The Bad: Air Bubblez
These are tested-tried-n-true grips. Oury makes grips for all kinds of handlebars. Their bike grip is dialed. I picked up 2 sets of these at Sea Otter 2012, they had a tent their and were charging 5$ a set of grips. No brainer! I bought a set for my flat bar that is on my road bike, they are nice and sticky and thick. The thickness really helps absorb some of the road harshness transferred from my stiff road bike. I would recommend these especially if you have large hands. Also they will never wear down because of how huge each section of the grip is.
When you put the grip on it naturally traps air between the inside of your handlebar, so you have to stick a pin at the end of the grip or it will bubble up a bit.
