Specialized Roval Traverse SL Fattie 27.5in 148 Wheelset Carbon/Black

The Roval Traverse SL Fattie 27.5in 148 Wheelset is built with a light overall weight, stiffness and durability.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 Roval made it a reality. The Roval Traverse SL Fattie 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.Along with light overall weight stiffness and durability; another top priority for the Traverse SL was the ease of use. First off Roval got rid of the creaky straight-pull spokes and corrosion-prone alloy nipples. Next up they landed on 28 j-bend spokes for both the front and rear wheels that are all the same length, making it easy to find replacements if needed. And finally, they engineered a new hub design with a wider profile and higher flange to aid in overall stiffness.What's with the big-boned name you ask? The Roval 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 millimetres for decades and they've been long overdue for a change. In the search for a better wheel design, Roval engineers began testing 2.3- to 2.5-inch tires on 45-millimetre-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. Such as, adding additional tyre volume which better supports the tyres 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.After determining the width they began designing the rim using the knowledge that they gained when developing the Control SL. With this, they started with their zero bead hook technology that gets rid of the weak spot found in a traditional wheel and combined it with the wider profile to make a carbon rim that effectively dissipates forces. This way you can take abuse from rocks without the worry of cracks or dents. Okay, so they're strong impact-resistant and tyre supporting... they must be heavy right? Wrong. Even though Fattie is in their name they're far from fat.To achieve this weight Roval hand-build their rims to their own alloy hubs using only the highest quality DT Swiss competition race spokes. Inside their 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, Roval chooses 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 track - the Traverse SL Fattie has you covered.Roval Traverse SL Fattie 27.5in 148 Wheelset SpecificationsRim type: carbon clincher, 2bliss ready, zero bead hook design.
