Going light doesn’t mean recklessly cutting weight. We kept these wheels 28h for reliable performance and durability.

Ethos Ti70 Hub

The perfect hub: hook-flange ratchet hubs with 70 points of engagement and lightweight titanium freehubs, designed with Berd and Erase.

Ride Feel

The Ethos SL is a purpose-built ultralight race wheel designed to ride better, not just weigh less. With a 30mm internal width and a full 28-spoke count front and rear, it avoids the concessions of other ultralight race wheels. Every detail was optimized for performance — from revised carbon layups to a race-tuned rim profile. Paired with Ethos Ti70 hubs and Berd spokes, Ethos SL is one of the lightest XC race wheelsets in the world, built for real race-day performance.

wheel features

Are NOBL rims tubeless-compatible? +
Yes. All NOBL rims are hookless and tubeless-ready from the factory. NOBL tubeless tape and Flatline valves are included. Max tyre pressure: 30 psi / 2.1 bar. Recommended tyres: 2.4–2.6" for enduro/gravity rims; 2.0–2.4" for trail rims.
How long does it take to build a set? +
Lead time is 7–14 days from Cumberland, BC. Every set is hand-built, hand-tensioned, and hand-trued before it ships. Rush builds are available — contact us directly.
What does the lifetime warranty cover? +
All NOBL rims are backed by a lifetime no-fault warranty. Break a rim while riding your bike — NOBL sends you a replacement. You only pay shipping. No questions, no inspections, no buy-back games.
Can I specify my own hub? +

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.
