Roval Traverse SL Fattie 27.5 148 Wheelset

Trail wheels often fall into two categories—they’re either heavy and durable or light and flexy. And because of this, a lightweight, wide-profile, and enduro-ready carbon wheel seems like something only found in a fairytale, but lucky for you, we made it a reality. The Traverse SL Fattie 27.5 puts all the flick'able, nimble features you need in an all-mountain wheel into one package, and it has the results to prove it.

What's with the big-boned name, you ask? The Traverse SL Fatties may be wide, but with a 30mm inner rim width, they’re far from the girth of a fat bike rim. But let's talk width. You've probably noticed that mountain bike rim widths have hovered between 19 and 23 millimeters for decades, and they've been long overdue for a change. In the search for a better wheel design, our engineers began testing 2.3- to 2.5-inch tires on 45-millimeter-wide fat bike rims to see what, if any, benefits could be found. It only took them a few rides to realize that the wider rims offered a variety of advantages, like adding additional tire volume, which better supports the tires in hard cornering, greatly improves traction because of the ability to run lower pressures, and noticeably increases rim stiffness. They did note that there is an occurrence of diminishing returns with increasing width, however, and after testing everything from 25 to 45mm, determined that a 30mm inner width is optimal.

To achieve this weight, we hand-build our rims to our own alloy hubs, using only the highest quality DT Swiss Competition Race spokes. Inside our hubs, you'll find DT Swiss 240 internals with a quick engaging 54t DT Swiss star ratchet system in the rear that allows you to power over rocks and roots without delay. And while machines do a pretty good job of building wheels, we choose professionally trained humans because they do so with an artistic touch that makes for minimal flaws.

Whether you need a carbon wheelset to get you through an enduro stage or one to shred your local rock garden, the Traverse SL Fattie has you covered.
