Years ago I dreamed a dream of cantilevered breaks. Specifically Paul's Touring Cantilevers, which would -- I assured my self -- so class up the bike that would not only stop faster but go faster as well. One day I did, in fact, get a set of Paul's and only had to pay 50 bucks each which is about half price. And no they weren't stolen. They look like this only mine are silver.
The thing is they are real pain to adjust and the rear one's needed constant attention to come even close to working. On the plus side all the parts are replaceable. The other day, I was adjusting the rear one and broke a bolt. As luck would have it, I had a spare Tektro sitting in the parts muddle. I figured while I could wait to fix the Paul's and struggle by with the cheaper break, it cost me 20 odd dollars and looks like this:
Others out there may have different opinions, they are, of course, 100% wrong.
