535.8 mi on SLR then big, fat rear blow out that ruined tire and tube. Cheap Bontrager R3's only lasted 536 mi then blew out the side wall w no damage from road, just a less than desireable tire.
I put on a full new set of 28 mm Continental 4000 II's with a new set of Specialized 20-28 tubes w 48 mm presta valves. So now I should be safe. Thank god this didn't happen on Mt Lemmon's decent. No more Bontrager tubes or tires for me.
-- This ride w Tim got rained out just as we were turning off Moore onto Dove Mt. My blow out happened 1/2 way south on La Canada. Sharon had to come and pick me up since the rip in the tire was so long that Larry W.'s boot couldn't contain it with a new tube. He and Terry helped me but ultimately rode on while I waited for Sharon to bail me out.
Cold day, then cold and wet day. Big storm coming!
