While aerodynamics are at the heart of everything we do, the Roval SL 35 front wheel is far from a one-trick pony. Instead, it utilizes a 17mm-wide internal rim width to make the perfect tire profile. Not only does this enhance the wheel's aero benefits, but it also increases the tracking stability and performance of the wheel. Not stopping there, however, we also built the SL 35 to have a durable alloy rim construction that can withstand years of abuse without sacrificing rigidity or speed. And to build on this, each wheel is hand-built with Roval hubs and DT Swiss spokes.
