I have found the best place for any kind of bike advice is to start here. You gals are the best so far in helping out with any kind of bike issues.

On that note - help!! Last summer I developed tendonitis in my Achilles. I went for a bike fitting, hoping it would help. The guy at the LBS immediately lectured me on the height of saddle. I took it well and lowered the saddle. Well, since then not only does the Achilles tendons still act up but now I have knee pain. The guy at the LBS was kind of a jerk and I came away feeling like he thought I was an idiot and he was the better person. An *** in effect. So now I don't know what to do. I hate paying for yet another fitting simply to have the same experience but this is not working. What I know is that the cleat on my right leg feels off but no matter how much I play with it or ask others to adjust it, I just can't get it right - and that's the leg that hurts. I also know my knees hurt at the saddle height.
Any advice would be helpful. Thank you.
