Reserve Wheels is proud to partner with German hub manufacturer Tune for a limited run of high-performance, high-speed wheelsets. Laced exclusively to Reserve's SL Turbulent Aero rims, Tune Pico hubs are a brand-new addition to the Tune hub lineup that are purpose-built for Reserve rims, and use straight-pull, bladed carbon spokes. 

The dedicated hub design and perfect alignment mean that the carbon spokes don’t need to bend or twist between the hub and the rim, creating a stiffer, stronger wheel. On the road, this gives you a more planted feel with exceptional energy transfer for sprints and breakaways. Reduced stress at the spoke nipple, and optimized load distribution ensure long-term durability.

Pico hub axles are hard anodized and the freehub body can be upgraded from 69 to 138 points of engagement (5.2 and 2.6 degrees of engagement, respectively). They are machined from 7075-T6 alloy and weigh 275g per set, including the driver body and rotor lockrings. 

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. This is your ultimate all-around wheelset. 

Fast enough for Simon Yates to take a stage ten win at the 2025 Tour de France and strong enough to charge the Paris-Roubaix. 

FEATURES:

  • 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.
  • Built for a Lifetime: All Reserve wheels are built around a simple principle: we have your back. That means no rider weight limits, an industry-leading Lifetime Warranty, safe semi-hooked rim designs and comprehensive customer service.
