The IRD Polaris crankset is designed for riders who want clean shifting, dependable performance, and the freedom to run either 1x or 2x without swapping to a whole new system. Whether you're building up a gravel rig, refreshing a commuter, or dialing in a touring bike that needs real‑world gearing, the Polaris delivers smooth power transfer and rock‑solid reliability.

Choose the Direct Mount 38t for a simple, efficient 1x setup, or go with the 42/26t spider for a wide‑range 2x drivetrain that climbs like a mountain goat and still holds speed on the flats. Either way, you get IRD’s signature machining, clean aesthetics, and a bottom bracket included to make installation straightforward.

Grizzly Notes

Bakersfield riding isn’t one‑size‑fits‑all. Some days you’re grinding up Panorama, other days you’re cruising the river path, and sometimes you’re loaded down with groceries or gear. The Polaris crankset gives you the flexibility to build your bike around your life — not the other way around.
