RebeccaAnn--

Yes, I am also a Rebecca.

Thanks for the tips on the handlebars.
I put in 50 miles again yesterday and I find that I get annoyed at being unable to alter my positioning--hence, no relief for any body part. Meanwhile, my partner can hold his handlebars, rest on bars he's got in the center of his handlebars, lean forward, sit up, etc. (Grumble, grumble)
Also developed left knee pain yesterday that went away quickly, but am not sure what its source is/was.
Anyhow, I'll check into your suggestions.
Thanks!
