Looking for best tires for mountains (descending), bad roads at times, and short segments of gravel during a week 400 mile road bike tour. Presently riding Continental 4000S 700 x 23mm clinchers on Zipp 303's, Trek Madone 5.9 and on flat well paved roads.
We will be pleasure touring,no racing.
Have been looking and thinking Continental Gatorskins, 700 x 25mm, might be the choice.
Am also thinking of leaving the ZIPPs at home and riding either Ksyrium SL's or Bontrager Race Lites (came on my bike when new).
Appreciate the advice and thanks in advance for responding.
