Description

This is your ultimate all-around wheelset. Lose every possible gram of weight, without losing any of the strength or reliability that Reserve is known for. Carbon spokes, lifetime warranty, no-fault crash replacement and no restrictions on rider weight or tire choice.

Turbulent Aero design keeps the handling smooth while delivering class-leading aerodynamic gains by pairing the shorter front rim with a taller rear rim. More speed, with more control.

Fast enough for Pauline Ferrand-Prévot to take the GC and the yellow jersey at the 2025 Tour de France Femmes. Our SL wheels come with carbon spokes and are only available paired with our lightest hubsets.

*XDr & HG driver bodies, centerlock rings and spare carbon spokes included.

The Wheel for Race Day, Everyday

From your lunch ride to Pauline Ferrand Prevost’s Tour winning efforts, this wheelset is the silver bullet. 42|49 is light enough to climb and gives you just enough depth to cut through wind without giving up control.

Lighter & Stronger

Built to be as light as possible—without trading away strength, stiffness, or durability. Carbon spokes, purpose-built hubs, and an advanced SL rim layup work together as a system. Less weight. No shortcuts. Pure performance.

Turbulent Aero

Reserve’s aerodynamic protocol uses real-world wind data to develop wheels that are both faster and more stable on the road, not just the wind tunnel. More speed. More control. Turbulent Aero.
