Hey all - Slowman and I recently had the opportunity to do a full tour of ENVE's HQ on Ogden. I just published a tour of their testing facility, which included a gaggle of tire test rigs. Of particular interest is their massive rolling resistance tester, and their machine that measures tire bead diameter and stiffness. The latter is what drives their approved/unapproved tubeless tire list for the AR series wheels, and we'll have more editorial coming about this topic (it's important stuff).
