Model Description

Based on the merits of the ROS 9, the ROS 9+ takes the rowdy steel hardtail base and adds plus size tyres for big miles and big smiles. The ROS 9+ still features super short chainstays and slack head angle making it playful and fun on the trail, yet thanks to the 29er plus tyres its super versatile and can turn its hand to anything from out and out trail riding to big adventure rides in the country. The 4130 ChroMoly tubing offers a durable, strong platform with a superb ride quality and is designed as a 1x specific frame to accommodate the short chainstays and 3.0” tyres clearance at the rear.
