Guards against hands slipping out from grip. Extra leverage for uphill pull and an additional position for resting hands.
Quality Good but not user friendly
Great product for MTB suitable for large hands , fitted really nice on my MTB bike and are very comfortable while riding..
Fitting is easy but may taker a ride or two to sort out the perfect angle. Bars are not covered with rubber so could be cold in winter; however, I always wear winter gloves so for me, not a problem. Fitted my Btwin with no difficulty.
Easy to fit. Nice shape. Good size. Well priced
No real negs.
