We took all of our favorite features certified road tubeless rims, wider rim width, durable Echo hubs and wrapped them all up into a lightweight, fiercely fast package. The EA90 SLX is Easton's top-of-the-line aluminum wheelset. These are race wheels by all accounts, yet strong enough for daily duty and cyclocross trail riding. These wheels roll smooth and fast, thanks in part to the wide 17.5-millimeter internal rim. And with durable Echo hubs, EA90 SLX wheels are built to keep rolling smooth season after season. Don't be fooled by all of the technology packed into these wheels they are easily serviceable. They roll on standard bearings and standard double-butted straight pull spokes. The only proprietary pieces are the dual-threaded spoke nipples which are serviced just like standard nipples with no special tools necessary.
