I spend a lot of time on my bike and somehow I seem to methodically destroy the foam hand grips on a regular basis. They just disintegrate.
Today, one fell off on the road and the other was cracked and getting ready to.
I live many miles from a bike or sports supply store...so I had an idea. I had some foam sleeves for insulating pipes. They are so cheap, and I buy it by the meter but basically, the same kind of foam. I cut 2 pieces to size and wiggled them on. They fit snuggly and are more comfortable than the official foam bike grips plus the kind of silvery grey color of the foam matches my bike finish.When they disintegrate, I'll just cut some more!
