Roy, this has been covered in the past on this list or on the 650B list so a search of archives should disclose those cantis that have more adjustability. I have an old, cheap pair of shijmanos (Altus model) that do reach up enough to reach 584 from 559. The real solution is to get some Paul Moto BMX V-brakes. I found some used on ebay for not too much ( but then I used to look constantly for these very items). This year my Atlantis (56 cm with 559 wheels) will be used some of the year with some new 650b wheels I will build. Later in the summer the touring 559 wheels will be back on for a tour down the west coast. On Feb 1, 2011, at 9:16 AM, Roy Yates wrote:
