Pedros are good...that was what I always used before discovering the Michelins.
So, here's the story - Pedros were the best I knew about. I bought a flip bike and I found these weird yellow levers in the saddle bag and tossed them aside. I pretty much forgot about them. A few months later I was changing a MONSTER tire...it broke a Pedros and I'd never seen that. It broke a SECOND Pedros. I had pretty much resolved myself to surrender when I remembered those weird yellow levers. What the heck I thought...might as well try. Seconds later the monster tire was off with little hassle.
