About 25+ years ago when Contis first were imported experienced a front tire blowoff in a mass start lineup . . . Kaboom! . . . Wondered whose tire had exploded.
Oh . . . ours!
That's before the switch to kevlar beaded tires from wire beaded.
We've been using Maxxis Re-Fuse tires 700x25 for the past several years with excellent results on our Zona tandem.
Just our input.
