Brazeons and stock wheels. The brazeons part is fading due to the new fangled dropouts companies are using. For grins look at the evolution of the surly dropouts.
What do I own? A Rodriguez 26in wheeled travel bike and a Last gen USA made cdale t-series. The first cdale T series I owned, RIP was the low budget version. To make their price point cannondale used *poop*-tastic wheels and an explosive BB. I get it, but gosh they were bad.
