Description
The Tune Nano Gravel 45 is a purpose-built gravel wheelset that sits at the intersection of speed and durability. It takes the core ideas behind the Tune Yokto platform and makes them usable in real gravel cycling conditions, with a more robust hub, conventional spoke interface, and fewer constraints on gearing.
At the center is Tune’s new Nano hub platform. It’s faster engaging, more versatile, and built to handle both race efforts and long days off-road. Paired with a 45 mm carbon rim and a modern 30 mm internal width, the wheelset is stable at speed and properly supports today’s wider gravel tires.
These are hooked rims, which matters. You get secure tire retention at pressure, broader tire compatibility, and fewer limitations when setting up your bike for different terrain.
Details like the integrated drain hole and raw UD finish aren’t cosmetic. They’re practical decisions. Water management, reduced risk during inflation, and a finish that hides wear instead of highlighting it.
Everything is built in-house in Germany. Light for the category. Durable where it counts. This is a gravel wheelset designed to be ridden hard, not managed carefully.
Features
Specs
Nano hub platform
Faster engagement (69 POE) with broader drivetrain compatibility. Built for real-world gravel use, not just weight targets.
45 mm / 30 mm rim profile
Stable at speed with meaningful tire support. Works with modern gravel tires in the 38–66 mm range.
Hooked carbon rims
Secure tire interface at pressure. No compromises on safety or compatibility.
Conventional spoke construction
Sapim CX-Ray spokes. Serviceable, reliable, and proven under load.
Integrated drain hole
Prevents internal pressure buildup and manages water ingress. Small detail, real impact.
Raw UD carbon finish
Lighter and more resistant to visible wear. Built for gravel, not showroom conditions.
In-house build
Hubs and wheels assembled in Germany. Tight control over tolerances and finish.
