NonPlus Components ADVENTURE55 ULTRA Gravel Wheelset
The lightest way through the roughest terrain. The ADVENTURE55 ULTRA is built for riders who refuse to compromise on speed, even in the toughest terrain. Starting at just 1125 g, it combines impressively low weight with exceptional strength, made possible by premium high modulus carbon.
The 55 mm adventure aero profile keeps your speed consistently high, even with wide gravel tires, making it the perfect choice for fast off-road racing and demanding adventures. The 32 mm wide gravel platform is fully optimized for high-volume tires, delivering maximum traction and control, ideal for tire widths from 42 to 70 mm.
Aerodynamically optimized carbon spokes ensure high stiffness and direct power transfer. Optionally, the wheelset is available with STEALTH aero spokes, where the spoke heads are hidden inside the rim bed, resulting in cleaner airflow, reduced drag, and even more speed. With dedicated front/rear engineering, both wheels are precisely tuned to their specific demands, ensuring maximum durability, minimal energy loss, and full control, no matter how rough the terrain gets.
As an added bonus, every ADVENTURE ULTRA wheelset comes with a wheel bag, so your new wheels are perfectly protected.
