EUROBIKE 2009: THE WHEEL DEAL
"Bill Shook at American Classic was very keen to show us a couple of new wheelsets, but also had a nice cutaway of their rear hub which shows very well how the mechanism differs from a standard rear hub. Instead of using springs to push the pawls against the ratchet, the AC hub uses a timing ring which engages all of the pawls mechanically, at the same time. The pawls don't drag across the the ratchet, so it doesn't wear and there's no unnecessary friction, and because all six pawls engage at the same time there's less stress on the ratchet, meaning that American Classic can use an alloy one."road.cc
