We’re on this ride together.
Put simply, you’re supporting us with your purchase, and we’ll be here to support you in your ride experience. If one of our products fails due to a manufacturing defect within the first five years of ownership, we’re going to take care of you by repairing or replacing it. And for everything else, we’re still going to take care of you via at-cost crash replacements and service guidance.
At-Cost Crash Replacements
Even the most thoughtfully-engineered products have their limits, and in the unlikely event that you exceed ours, we’ll want to get you back in the saddle as quickly and painlessly as possible. That’s why, rather than heavily marking up our products and offering “discounted” crash replacements from which we still profit, we offer at-cost replacements on non-wear items and direct pricing on everything else. Simply contact us at email@example.com with photos and a description along with any serial numbers (under the rim tape in the case of a rim) and we’ll get you sorted out.
Our Optimized Rim Profile
With its generous 28mm internal width, our atara 650b rim supports 47mm - 2.4” tires at lower pressures without tire squirm for greater traction, control, and comfort. 3mm of asymmetry balances spoke angles for higher overall tension and a stronger, more durable wheel with a standard spoke count. Its robust blended-modulus layup is formed in precision-polished molds to deliver a raw carbon finish free of heavy cosmetic coatings for high strength-to-weight and impact-resistance, while heavier or more aggressive riders can add tire inserts for even more ruggedness from a lighter overall system.
Hubs Worth Investing In
At the heart of every Lōgōs wheel is the arché|os open standard hubset. Built to the now open “star ratchet” standard patented by Hügi in the 90s and later popularized by DT Swiss, arché|os employs the superior dual-sprung variant that established this standard as the “archetype” for bombproof reliability. All variants distribute torsional loads across many (in our case 36) hardened teeth machined into two solid, interlocking rings for an immensely robust engagement interface that is resilient to the misclocking-based point-loading failures that lead pawl-based hubs to fail.
A Build We Stand Behind
All of our wheels are laced with Pillar Wing spokes as much for their exceptional strength, durability, and serviceability as for their light weight and slight aerodynamic benefit.
Exposed brass nipples always so that a few years down the road when it's time for a truing service is a breeze.
Every lōgōs wheel is precision prepped, machine-built, hand-finished, and machine-checked to ensure the tightest tolerances for years of trouble-free riding.
