Frankly I wasn't sure the bad ends would work for my mountain bike. I have found on my (so far) one trail ride that the size and curve of these particular grips with integrated bar ends took away much of my fear when I got close to trees as I went around roots. I really wish they would work with my x0 grips on my Gunnar though. The bar ends are helpful, especially if you have any had problems. Core strength is good as well, but with arthritis they are heaven-sent.
