I ask, because my knee problem seems to be coming back. It had me off the bike for seven weeks a couple of years ago, then cleared up, but now it's barking every now and then. Not too bad, and I can still ride, but I'd like to know my options.
If I ever go 'bent, it will be low-end to start because they are so expensive! What's a good first 'bent? I'd be doing 15-20 milers on it, mostly in urban environments. Thanks!
