Circles｜サークルズ

A mountain bike style built for riding trails after the rain.
A mountain bike helmet that properly protects the face, paired with sunglasses to keep mud splatter out of the eyes on the previous day's soaked, muddy trails — a setup that lets you push harder with confidence.

Running tubeless is the key move on the tires, keeping puncture risk down even at lower pressures.

Another detail worth noting is the front-to-rear tire combo. The front runs a pattern with taller knobs for stronger grip, biting into the mud, while the rear balances grip with rolling efficiency. That front/rear split delivers a stable ride even through the muck.
