I have been religiously pumping my gossamer 70C X 60 Big Ones to 20 psi for combined pavement and dirt, thinking that ~20 was necessary to minimize wallow on paved corners, but on an extended dirt ride today on usually sandy soil that had been extensively compacted by moisture and then chopped up by horses and Conservancy District trucks, 20 felt like wood rims on railroad ties, so I dropped both tires to ~16. That did mitigate the chop (tho' little really makes horse hoof divots and washboard comfortable except suspension) and observing carefully during cornering on pavement at speed I didn't notice as much wallow as I had feared. Me 170 clothed and shod for cool weather, bike and kit and bags and contents adding another 45 lb or so.
So I'm curious: Those of you who use 60 mm tires: what pressure or pressures, and on what surfaces? And how much do you and kit weigh? Funny: I'd been riding the lightweight fixie gofast with Naches Passes at 39 mm (skinny rims) and 30-35 psi on the same roads and found that they were at least slightly smoother on the chop than the BOs at 20. The NPs are far less gossamer light per unit vol than the Big Ones. -- ----------------------------------------------------------------------- Patrick Moore Alburquerque, Nuevo Mexico, Etats Unis d'Amerique, Orbis Terrarum -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
