Fox's new 38 and RockShox's also-new Zeb are both burly single-crown forks that employ 38mm diameter upper tubes, high-end dampers, and a lot of travel to be ready for the rowdiest of riding. Our own Dan Roberts has spent more than the last six months riding both, including countless back-to-back laps on the local steeps of Champéry, Switzerland, and all over Europe. We sat down with Dan and did a deep dive on each fork.
