    • I have a Boulder Brevet, which is 700c. It is far and away the best riding bike I’ve ever owned. And frankly, when I decided I wanted a 650b to complement that bike Boulder was my very first thought. Despite numerous messages and emails, I never got a return call. I wound up getting a Cycles Toussaint instead, with no regrets about doing that. It was a relatively economically way to get into the 650b pool to see if it was all hype or something I wanted to ride. I do like the ride quality of the wide, supple tires but I wanted something a bit livelier than the CT. I sold that frame, but kept the components to use on a 650b frame that better matched the 700c experience I get with my Boulder…so I called Boulder again – and once again never got a return call. They must really be busy! Now I don’t mean to imply that Jeff Lyon was my second choice – I just hadn’t realized I could afford one of his frames. The BQ review of the L’Avecaise a couple years ago was enticing, and I remember thinking at the time that Jan Heine was describing a 650b frame that sounded a lot like what I wanted. So when the time came that I had a bit of extra cash in my bike fund I decided to give Jeff a call. He’s a great guy and easy to work with, and I’m pretty pleased with his work. Oh, and it turns out I can afford his work also!

    • Jeff builds fillet brazed frames. Much as I love lugs, the joins on this frame are really terrific. I love craftsmanship, and he has it in spades. Check out the rake of that fork…just beautiful, right? I also wound up with the wet paint option, which is pretty sharp looking.
