Compliant, responsive, and lighter than most XC wheelsets, Ethos Trail defies categorization.
Revised carbon layups and reduced torsional stiffness create a wheel that’s snappy under power, supple through chatter, and flat-out fun. Built to smash corners and stay smooth over every bump.
With a shallow 18.5-19mm front & rear specific rim profile, Ethos Trail is our most compliant trail wheelset with grip that you can count on. At 1338g, it weighs less than many XC wheels, but has the strength and stiffness to take on every trail.
The perfect hub: hook-flange ratchet hubs with 70 points of engagement and lightweight titanium freehubs, designed with Berd and Erase.
The front rim is 80g lighter and more compliant, with .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.
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.
Built to match the performance of Ethos rims and the world’s lightest spokes. Developed by NOBL in collaboration with Berd and Erase Components, it pairs a lightweight titanium freehub with a fast-engaging 70-tooth star ratchet system for a crisp 5.14° engagement, ensuring precise power transfer on every pedal stroke. Berd’s proprietary Hook Flange design makes spoke installation secure and straightforward while optimizing strength at the interface and maintaining compatibility with Berd PolyLight X spokes. At just 331g for a centerlock hubset, the Ti70 is a lightweight, durable, and highly efficient hub that maximizes the performance of Ethos rims and Berd spokes, making it equally capable for XC racing and aggressive enduro riding.
Made from Dyneema®, Berd spokes deliver an industry-leading strength-to-weight ratio—up to 12 times stronger than steel by weight. Their fibre construction naturally absorbs high-frequency vibrations, reduces trail feedback and improves traction. PolyLight X spokes feature a 50% larger diameter (2.7 mm) than standard PolyLight spokes. This increases stiffness by 44% and improves abrasion resistance, adding strength and impact durability while still maintaining significant weight savings and ride compliance. The perfect spoke for Ethos Enduro wheelsets.
