Ditto both Mtnroads and Hawkgrove. That's pretty good testimony on your basic bike - and ours. By the way, I went to the Specialized site and they don't list a 26 X 1.5 Nimbus Armadillo. Strange. I called my LBS and they said they have them on the shelf. You asked me about h'bars in your PM to me. I can't remember if I told you: The 830 has North Roads and I haven't settled on the 520 yet.
