most people rave about one product when it comes to serious touring:
brooks b17 saddle
here is the suspended version of b17 called flyer:
the bikefriday nwt is said to provide a harsh ride on bad roads. this saddle got an estimated 100 year old mechanical spring suspension which is supposed to work well on long tours and even on commutes. i bought this saddle in black matching the color of my bike for only 87 bucks@universalcycles. definitely a steal!
at the moment i find wtb the best saddles for longer rides. i have to test brooks and see if it works for me. if i keep it, i will just treat it with a waterproof agent and skip the voodoo...
portland is one of the top cities for biking in the world. there are many bike shops where you can find advice.
