Well the Schwalbe Thunder Burts arrived Wednesday from Germany after clearing customs. After work that night I mounted them and made sure they were seated properly. I inflated them to about 50 psi then reduced them to 40 psi, they have an inflation range between 30-55 psi. These were like the Big Ben’s super easy to mount. Just for fun and geekiness I calipered them. Mounted on DT Swiss XR430 rims with an outside diameter of 23mm they were 47.5mm at the above 40 psi.
Thursday I took them for a shake down ride over mixed terrain, asphalt and sandy loose trail, my usual. My initial impressions, sure footed on dirt where the BB’s left me easing up on a loose dirt turn the TB’s seemed to dig in inspiring confidence. On pavement they were quick rolling dare I say fast, yeah they were fast and easy to get rolling since they weigh half as much as the BB’s. I listened to hear if they made much noise, but since they have a nearly slick center crown they were silent.
So I’ve lightened up my stout Atlantis and figure I have the rubber for my big Summer tour in the PNW.
Still waiting on some parts to roll in before I can redo my cockpit. Thanks for looking and keep the rubber side down.
