For others reading, 100% agree with Nick - Conti GP Urban 700 x 35, and with TPU tubes. I sold one set when I sold a bike, and am on them again with another.
I run them on my upright bike, and hang with the other folks born in the 50s and on their 28mm GP5000 equipped carbon fiber road bikes. As for bigger tires not being slower, well, that's just silly as a general rule. Take a ride up the deliciously smooth HC Gibraltar Road <https://mycols.app/en/climb/gibraltar-road-santa-barbara> here in California, first with 2.6 knobbies, then with the Conti GPs (and lighter wheels!). I like to climb, but in my seventh decade, extended zone four and five rides are no longer recommended! The physics of tires and road surface is a matter of impedance matching: A 28mm Conti GP won't be as generally efficient over ruts, roots, and rocks as will a nice 2.6 knobby, and conversely (see above), and likewise gravel riding is great on a 38-42mm tire, but with our smooth roads (the Montecito residents just will not stand for chipseal) 35mm is my max! - Chris On Friday, February 13, 2026 at 1:17:57 PM UTC-8 Nick Payne wrote: > For 700x35 tyres I've switched from Bon Jon Pass to Conti GP Urban, as to > me they feel the same to ride, and in this country the Contis are about > half the price. > > Nick Payne > -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
