A proven staple of the Easton carbon wheel lineup, our EC90 SL wheels have suffered and survived the dedicated testing of countless pro riders and cyclocross elites. And, now, with the release of our Vault hub, we enhance an already dynamic wheelset with our incredible new hub. To create an even more competitive wheelset, we laced the EC90 SL disc Fantom rims to our tested Vault hub - designed to exceed your needs from tarmac to off camber cross courses. Larger bearings on a wider bearing stance and improved seals help to push reliability to a new level. A reversed drive ring configuration gives 60 points of engagement at just 6-degrees for instant acceleration. Included in the box are tool-free swappable end-caps for all major axle standards and 5 extra straight-pull Sapim spokes that match the uniform spoke length through out both wheels. And at 48 grams lighter than our M1 hub, you can enjoy further gram-saving benefits of an already lightweight setup.
