GROWN RAT | Modern ATB where nostalgia and modernity intersect
A 26-inch all-terrain bike that inherits the charm of 80s and 90s ATBs while being re-engineered for modern riding styles.
The GROWN RAT is a modern 26-inch ATB inspired by 80s and 90s fully rigid ATBs, updated to suit contemporary riding styles.
It combines a somewhat nostalgic silhouette with modern specifications such as disc brake compatibility and support for 26x2.3 inch tires. More than just a revival, it offers a level of completeness that makes you think, "This is what I want to ride now."
The frame uses TANGE CHAMPION No.3 chromoly tubing. It combines the supple ride quality and durability characteristic of chromoly, making it active in a wide range of fields from city riding to forest road touring and bikepacking.
Furthermore, abundant eyelets are placed around the fork, downtube, and seat stays. You can freely attach racks, cargo cages, etc., making it fun to customize it into your own unique bike.
The rugged texture of the Parker RAW finish and the intentionally exposed TANGE tubing model number are also unique characteristics of this bike. It exudes its presence both in the city and in nature.
