German lightweight specialists Tune have an all-new Nano Gravel 45 carbon gravel bike wheelset that checks a lot of boxes. They are really light at just 1335g for the pair. They have a wide 30mm inner width and a hooked profile that makes them a solid match for tube and tubeless setups from 38mm all the way up to 2.5″ tires. Add in, a versatile 45mm depth that offers just enough gains in both aerodynamics and high-performance stiffness. And top it all off with lust-worthy, high-engagement Tune hubs!
Tune Nano Gravel 45 lightweight all-rounder carbon gravel bike wheels
At only 1355g for the set, the new Tune Nano Gravel 45 wheels are some of the lightest you’ll find in their mid-depth 45mm deep aero gravel all-rounder category. Plus, with a 30mm internal hooked, tubeless-ready carbon rim profile, they offer reliable low-pressure support for the widest modern gravel tires, but can still be safely run with narrower tires and even with tubes. ETRTO officially classifies the wheels for 47-57mm tires. But Tune’s own testing shows secure fit and performance from 38mm all the way up to 66mm/2.5″ tires.
In fact, with a 36mm outer carbon rim width, Tune says they even though they are optimized for wider 50 & 55mm tires, they are fastest with 40 & 45mm gravel race tires.
Plus, they builds the Nano Gravel wheels built tough with classic, beautifully CNC-machined Tune Nano CL hubs, even letting you pick from staid black, shiny silver, or flashy red.
