I bought ten of them. I'll use them on tubes and such if nothing else. Perhaps I was still riding on the high of receiving a new Frank Jones Sr frame on Monday, which would have been a bargain at twice the price—the most beautiful frame I've ever personally seen, and it's a single-speed Riv, which I've wanted for years. An extra $100 in future business to help Grant and company pay for all these neat new bikes is well worth it.
