Review on SAPLIZE Bike Handlebar Grips - Multiple Color/Design Options, Ergonomic Aluminum Double Lock-on for Mountain Bikes, MTB BMX, Downhill, Folding, Urban Bicycles, Scooters by Bankroll Reed

They are great for regular cyclists. I installed them before a recent trip to Colorado and hated them. On long stretches of descent, my thumbs were pressing against the brake levers/switches. I tried several settings but nothing helped. Finally, take your hands off the "palm rest" while pressing against the grate. I had blisters on the backs of both thumbs. The handles don't have enough grip. A little too plastic feeling. I'm glad I can return them.
