snipped:
"For a while, you could buy tires branded "Challenge" that were manufactured in Clement's former Thai factory. These tires were essentially the same as the classic Clements (if sometimes a little lumpy). However, I have not seen them in the US market for a while. So, that venture might have closed."
we have a pretty deep sponsorship gig with Challenge Tires. they are among the best 'cross tires available.
