HOW I ROLL CHAMP | A bike that brings the beauty of Keirin culture to the streets, easily accessible to all
The HOW I ROLL CHAMP is often described as "cool" and "beautiful" in stores.
With its slender chromoly frame, beautiful horizontal silhouette, and classic component choices, it embodies respect for Keirin culture while being a single-speed bike that even first-timers can ride with ease.
Enjoy the direct ride characteristic of a track bike with a fixed gear, or cruise around town with a freewheel. This bike strikes a perfect balance between beauty and ease of use, making it accessible to everyone.
The CHAMP's appeal lies first and foremost in its beautiful appearance. Rather than an eccentric design, it features a very simple configuration, with the slender chromoly tubing and horizontal frame creating a very neat line.
A major charm of this bike is that you can easily enjoy the "beautiful form" that Japanese Keirin bicycles have refined over a long time, in a complete bike package.
The world view is maintained even in the selection of detailed parts.
Not just the frame, the parts selection is also excellent.
The components, such as the quill stem, DIA-COMPE brake levers, polished rims, and classic-shaped saddle, are chosen to maintain the overall aesthetic.
Despite being a complete bike in the ¥100,000 class, it strikes a very good balance between visual coherence and practicality. The finish clearly shows a love for Keirin and track bike culture.
Fixed or freewheel. The versatility to be enjoyed by beginners.
A serious look, but freedom in how you ride.
The rear hub features a flip-flop design, allowing you to choose between a fixed gear and a freewheel. You can enjoy the direct ride characteristic of a track bike with a fixed gear, or cruise leisurely around town with a freewheel.
It even looks good with a basket for everyday use, so it's not just for "fixie enthusiasts" but also highly recommended for those new to single-speed bikes.
The HOW I ROLL CHAMP is a beautiful and easy-to-ride single speed.
The HOW I ROLL CHAMP is a chromoly single-speed that allows you to easily enjoy the beautiful silhouette cultivated by Keirin culture in your daily life.
