NOBL Ethos XC Rear Wheel

NOBL Ethos XC Rear Wheel

Light when it counts. Tough when it has to be. The Ethos XC is the ultimate XC wheel. Berd spokes and a shallow rim profile deliver race-day weights, with a reinforced layup for real-world reliability.

Sub 1200g is obscenely light, but weight alone was not enough. The Ethos XC was built to ride better. Featuring shallow 18.5mm rims with front and rear-specific designs, these wheels are built for technical XC riding on the roughest terrain. Ethos XC rims are 21% stronger than the Ethos SL, with a more robust sidewall layup. Built with Berd spokes, they are wheels you can trust that fight fatigue on epic days on the trail.

The Details

The shallowest in the Ethos Series with an 18.5mm depth, these rims are made for the perfect balance of efficiency and compliance. Even with featherweight construction, reinforced sidewalls and layups make the Ethos XC 21% stronger than the Ethos SL. This gives them real-world durability, with the sidewall able to withstand strikes from rocks or debris that gets tossed into the wheel when the going gets rough.

With front and rear specific rim designs, Ethos XC is precisely tuned for XC racing. Up front, a lightweight, compliant construction minimizes rotational mass and enhances grip. Out back, a reinforced layup and wider rim lips increase impact resistance and tire support, engineered to withstand repeated hits.

hope pro 5 hubs

 The Signature Series is powered by Hope Pro 5 hubs. Tried and tested, the Pro 5 offers an unbeatable performance to price ratio, with a strong track record of reliability and serviceability.  

Faster Engagement: The rear hub features an offset 6-pawl freehub design, increasing engagement from 44 points (previous Pro 4 model) to 108 points (a quick 3.3° engagement), providing a faster, more responsive feel on the trail.

Reduced Drag: A new “zero drag” labyrinth seal and an improved ratchet and pawl system with updated springs greatly reduce friction and drag within the drive mechanism.

Improved Durability and Stiffness: The hub shell has a new profile designed to add stiffness 

without increasing weight. A new axle design accommodates larger, sealed stainless steel cartridge bearings in a better arrangement to increase load capacity and longevity.

E-Bike Freehub: Featuring a steel freehub body and all six pawls engaging simultaneously to handle the higher torque loads associated with e-bikes. (54 points of engagement vs 108 with the alloy freehub)

Serviceability and Support: True to Hope’s reputation, the Pro 5 is fully serviceable and rebuildable using simple tools, with a commitment to spare parts availability for at least 10 years after production ends.
