The bike you'll find yourself reaching for most often, whether for your daily commute or a weekend detour.

The supple ride provided by the chromoly frame and chromoly fork reduces fatigue during long rides and naturally adapts to everything from paved roads to rough surfaces.

Bringing the ATB Concept into Daily Life

Not defined by purpose. That's the essence of an ATB.

Unlike modern bikes optimized for specific uses like road, MTB, or cross bikes, ATBs transcend those boundaries.

Their appeal lies in the freedom of handling cities, suburbs, and unpaved roads with just one bike.

The MUIRWOODS 27.5 is an "entry-level ATB" that brings this concept together with a realistic price and ease of use.

Frame Design That Doesn't Limit Where You Ride

Chromoly: Combining Flexibility and Stability

The unique flexibility of a chromoly frame provides comfort on paved roads and stability on unpaved roads.

With a geometry that isn't overly aggressive, it's easy to handle at low speeds and feels secure at high speeds.

Additionally, the 27.5-inch wheels make it a good fit for Japanese body types and ensure excellent maneuverability.

Specifications That "Work Hard" from Daily Life to the Field

Simple and Practical Configuration

The 1x drivetrain with a wide gear range (11-51T) handles everything from city riding to hills and unpaved roads.

Hydraulic disc brakes (180mm front / 160mm rear) ensure stable stopping power, regardless of weather conditions.

With thick 27.5x2.35 tires and numerous mounts, it offers excellent expandability for customization and carrying capacity.

The Perfection of a "No-Fuss ATB"

The MUIRWOODS 27.5 is designed to make the versatile ATB concept accessible for everyday use, without making it feel overly specialized.

The flexibility of chromoly, the easy-to-handle geometry, and the balanced specifications all contribute to the philosophy of "not having to decide where to ride."

It's not too serious, but it's not lacking either. The MUIRWOODS 27.5 is the "just right bike" for venturing a little beyond the city.
