An uncompromising strength-to-weight ratio. At just 1551 grams, it delivers an impressive 185J of impact resistance, ready for the toughest enduro tracks.
The strongest enduro-specific wheelset we’ve ever built. A 19mm deep rim profile ensures compliance and traction that you can count on.
Front and rear–specific rim designs deliver the best of both worlds: a supple, forgiving front wheel for maximum traction, paired with a rear rim reinforced to handle hard hits with a stronger layup and wider bead.
The most compliant spokes just got stronger. 50% larger diameter (2.7 mm), delivering a 44% increase in stiffness and abrasion resistance compared to Berd PolyLight spokes.
The Ethos enduro rims are front- and rear-specific and feature a 30mm internal width with a shallow 19mm depth, which maximizes compliance and is tuned for optimal torsional flex with Berd spokes. The wide rim lips that taper below the bead distribute impact more effectively, giving the Enduro wheels an industry-leading strength-to-weight ratio. They are 28h only and available in 29”, 27.5” and Mullet configurations.
The front rim is 80g lighter and more compliant, with 0.5mm narrower rim lips, which improve traction and reduce rotational weight.
The rear rim is engineered to withstand harder hits and provide more support with a reinforced layup and wider rim lips that increase impact resistance.
Ethos rims are intentionally shallow for a more compliant ride feel. Reducing rim depth lowers overall torsional stiffness, allowing the wheel to absorb impacts while simultaneously introducing the right amount of lateral deflection, keeping you glued to your line, particularly on rough off-camber terrain. The result is a wheel that wants to go faster, providing precise tracking without feeling harsh.
Ethos rims feature wider, flared rim beads that increase the contact surface area at the outer diameter of the rim. This broader interface helps distribute impact forces across a larger area rather than concentrating load at a single point, improving overall impact resistance and durability.
Taking it a step further, the wide, flared bead is reinforced with a flexible material specifically developed to improve resistance to off-axis, one-sided impacts. On the trail, impacts are rarely evenly distributed across both rim beads; one-sided strikes are far more common.
The Ethos lineup introduces a concave profile developed to optimize torsional stiffness. This profile allowed us to reduce rim depth to improve compliance and fine-tune support, particularly when paired with BERD spokes.
NOBL Ethos Wheels feature a raised, flattened landing pad designed specifically for secure valve stem installation. This precise fit keeps the valve firmly in place, reducing movement and minimizing the risk of air leaks, keeping your tire pressure consistent.
For the best overall tubeless experience, the bead seat width and height, along with the drop channel diameter, are precisely engineered. Most riders will be able to install a tubeless-ready tire without the use of levers and inflate the tire fully without the use of a powerful air compressor.
All NOBL rims leave our high-end steel molds with a natural, raw finish without the need for post-production sanding and finishing. Without this abrasion, the carbon fibres remain fully intact and encapsulated in resin, preserving their structural integrity. Producing a paintless carbon rim is more demanding, but the result is a rim that’s not only cleaner in appearance, but inherently stronger.
