Many thanks to all who contributed!! I've had some time to think this whole thing through a bit more carefully. Truth be known, the Canyon I'm looking at has more going for it for me than just the brakes. It does offer both the low end gearing and the relaxed geometry more appropriate to my age group, what I get out of riding,, and frankly, my current abilities. It does so at a price point I can stomach on a fixed income. I'm still coming off a significant pelvic fracture, so there's time to consider options. Again, thanks y'all!
