HOW I ROLL CHAMP｜A Single Speed That Incorporates Keirin Culture into Modern Life
A bike that naturally combines respect for Keirin and a street aesthetic.
The HOW I ROLL CHAMP is inspired by Keirin, Japan's unique bicycle racing sport. It features a steep head angle, a slim silhouette, and a classic front fork that evoke the feel of a Keirin frame, while also offering practicality for urban riding.
The DROP BAR version uses the NJS-certified Nitto B123 Steel 380mm handlebars. The deep drop and beautiful curves create a unique presence, characteristic of the Keirin style.
Conversely, the FLAT HANDLE version offers a relaxed position for cruising around town without feeling stiff. The ability to choose according to your lifestyle and riding style is one of the CHAMP's appeals.
With a double-threaded hub that supports both fixed and freewheel, you can enjoy the direct ride of a fixed-gear bike or the casual fun of a single-speed. While the complete bike has a well-established aesthetic, it also leaves room for customization, allowing you to change the handlebars, saddle, pedals, and other parts to your liking.

While fewer Keirin-inspired complete bikes are being released, the CHAMP is one that truly feels "well-made." The inclusion of NJS Nitto B123 handlebars on the DROP BAR version from the start is quite a luxury. The unique, deep curve that makes you say, "Ah, this is it," the moment you grip them is truly special.
The flexibility of the 4130 chromoly frame is also comfortable, offering a distinct lightness even when just cruising around town. The FLAT HANDLE version has a more casual feel, making it a good fit for those who want to enjoy it mainly for commuting or daily use.
This model strikes an exquisite balance as a "fixed-gear bike for enjoying Keirin culture in the city," rather than a rigid Keirin racing bike.
