For us, this is a no brainer. At Polaris, we believe in durability, reliability, and a ride quality that stands the test of time. While carbon frames dominate the market, steel remains unrivaled in resilience and comfort. The Grace frames are built to last—absorbing vibrations and withstanding the demands of gravel riding with unmatched fatigue life and properties only steel can offer.

We’ve chosen Columbus Zona tubing because it offers the perfect balance of strength, weight, and versatility. Made in Italy, this seamless 25CroMo4 steel tubeset is triple- and double-butted, reinforcing critical areas while keeping the frame light and responsive. It’s the ideal foundation for a high-performance gravel bike built to go anywhere.

Zona’s increased wall thickness and strategically butted sections make it perfect for off-road exploration and demanding training rides. Whether you’re navigating technical terrain or clocking long miles, our Grace frames deliver the confidence and control that only high-quality steel can provide

Steel has been used in bicycle frames for over a century, and for good reason—it’s strong, repairable, and built to last. Columbus Zona tubing is designed to handle the stresses of real-world riding, with excellent resistance to fatigue and wear over time. The result is a frame that isn’t just handcrafted but engineered for long-term reliability—ready for countless miles on the road and trail.
