“Tune is proud to release the new, wide Nano Gravel 45, or what they líke to call the “Swiss army knife” of lightweight gravel wheelsets. With its 45 mm deep carbon rims, the Nano 45 is aerodynamically optimized—making it equally suited for gravel racing in addition to a wide range of rides off-road.”
The generous 30 mm internal rim width allows you to run wider tires at lower pressures, significantly increasing comfort, control, and traction across all terrain.
Hooked rims are the key advantage—by design. This means maximum tire compatibility along with an added level of safety when riding demanding terrain.
At just 1355 g (+/- 3%), the Nano Gravel 45 ranks among the lightest wheelsets in its class, but now offers a higher maximum system weight of 130 kg, compared to standard wheels. Like all other tune wheelsets, the Nano Gravel 45 comes with a full 10-year warranty, so riders are covered should anything go wrong.
The Nano CL hub offers 69 points of engagement, featuring Enduro bearings in steel or ceramic, and is available in Black, Red and Silver hub body colour options.
While the ETRTO recommends tyre widths of 47–57 mm for rims in this category, internal testing has shown that the Nano Gravel performs reliably across a much broader range, from 38 mm up to 66 mm. Designed around modern, high-volume gravel tyres, the platform is equally at home with more traditional 40–45 mm setups, offering riders the flexibility to tailor their bike for anything from fast, race-oriented riding to more demanding, off-road terrain.
Whether you’re racing, pushing the pace in group rides, or heading out on multi-day bikepacking trips, the Nano Gravel 45 is a versatile wheelset for all the many applications of the modern gravel rider.
