Frame Features & Specifications

One of the latest additions to the Chiru lineup! Chiru Fukaï has been developed to tackle the eclectic route of the Rhino Run. This 2,750km race from South Africa to Namibia passes through hot, dry desert areas, rolling hills, winding coastal roads and challenging mountainous regions.

Chiru Fukaï, a gravel monster over-equipped to go to the end of the adventure

This titanium gravel adventure frame has ovalized bases and is designed for a Boost standard single chainring transmission. Its geometry was designed around a 430mm rigid titanium CEC fork (#430T) thus allowing perfect compatibility with a 50mm reduced travel fork.

Chiru Fukaï is designed to carry a large luggage capacity. Integrated attachment points allow for up to 6 bottle holders! Enough to quench your thirst for adventure.

Chiru Fukaï, the hybrid MTB and gravel adventurer

Chiru Fukai incorporates SRAM UDH derailleur hangers. Chiru Fukaï’s transmission is MTB type and the brakes are Flat Mount standard, allowing it to be equipped with a gravel drop bar or flat handlebar. In terms of tires and for more comfort on rutted gravel trails, you will have the choice between 29×2.6″ or 27.5″x2.8″ (except for Size S: provide 27.5″x2.6″).
