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.

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.
