The real solution is probably using TUBE grips rather than tape. I have a couple of different old-school types that I got on ebay. They are MARVELOUS. They never come loose, they offer far better padding than tape, and they are durable like, like, like well, they are very durable.

I wonder why some company isn't making the old tube style grips for road bikes, but in snappy colors and designs, maybe even with ergonomic grips instead of flat. You could really offer some gel comfort then!

Hmm... an old idea made new again for modern man, perhaps?..
