Because these [Vittoria Randonneur Pro 700x32] are spendy tires

Randonneurs *well* past the recommended 80 psi (I think it was),
and kept the 700x37 Contacts 5-10 psi above the recommended
max 85.

You might have found the stock Contis more charismatic if you
underinflated them like you're doing with the Vittorias.

I'm trying to remember something I read here before regarding comfort
and efficiency on a bike. It was Fit, Fat, Fitness and ?????
I'm sure there are lots of reasons to switch 28s for 32s or the other
way around, change brands &c but if you want to make a big improvement
on your cycling by changing something I doubt tires are the easiest
way to do it. Me? I could drop 20 pounds.


And what kind of loudspeakers (and phono pickup) (would) do you
use? ;-)
