The new age of traction, stability, and speed has arrived, and its name is the Roval Traverse 38 SL Fattie 650b wheels. They feature 148mm rear and 110mm front axle widths, but to turn them into descending machines is the 38mm internal rim width. The extra width also allows for more tire volume, which means increased suppleness in the ride quality. And not only this, but the ample width also better supports the tire, meaning that you'll experience less "burping" when riding tubeless. These wheels also include the Roval tubeless plug system, which is an easy and super lightweight solution for tubeless setups. At the front hub, you'll get a 15x110mm thru-axle (end cap options included), and at the rear, the hub features DT Swiss internals for quick engagmenet. And to top everything off, these wheels are hand-built to ensure a painstaking attention to detail. Please note that this 148 version is exclusively designed for use with bikes designed with 110x15mm front axle and 148mm rear axle standards.
