If you've ever held a nice fly rod, you know what these cork grips feel like. Cork is firm but absorbs shock well. These are great for a town bike, or a commuter. They're not mountain bike grips. These are legit cork grips, not grips made of foam or rubber with some cork in there. That means they're very durable in normal use, but they can't take a hard crash, they'll crack. We like to coat these with two to three thin coats of clear or amber shellac. You can also leave them raw, but they'll turn grey with dirt and sweat. That's fine, as long as you're ok with it. We can do this for you. 3 coats = more durable, 2 coats more grippy. Install with Super 77 spray glue or Gorilla Glue. Keep a moist rag on hand to catch any that spills out. Spray inside the grip, a pretty good coating. Wait 1 minute, then install. Best to make sure you have enough bar exposed before you install, once they're one, they're not moving. Cork grips fit any 22.2mm Mountain style or swept back handlebar. Fits Nitto Albatross, Billie, Choco, Losco, Tosco bars, but not road diameter bars like Nitto Mustache Bars.
