5 Stars! I have been experiencing pretty regular pain in my right shoulder and both hands will go to sleep on the shortest of rides. After switching to these bars I have seen a HUGE improvement. After pedaling 63 miles yesterday I was stoked that my shoulder didn’t hurt at all. I had a slight amount of lower back pain, mostly from the rough terrain. My hands still got a little numb, but not nearly as bad as before. I think after more riding on these bars it should solve that problem entirely. The 720mm width makes for a great platform for control in both descending and technical climbs. Watch out for those side cactus though… they will get you! I would highly recommend these bars to any single speeder, or rider with hand, shoulder, or back pain on the bike!
