Product Detail

Premium Materials & Advanced Manufacturing

1. Alloy 6061 T6 Strength: Built with premium-grade aluminum alloy, heat-treated to T6 standards to ensure structural integrity and maximum resistance against stress.

2. 3D Forging Process: The sophisticated 3D forging technique refines the internal grain structure of the metal, providing superior strength-to-weight performance compared to standard machined stems.

Precision Engineering & Fitment

1. Versatile Sizing Options: Available in 85 mm and 100 mm extensions with an adjustable angle of 0° to 8° to help riders achieve their optimal ergonomic riding position.

2. Standard Fit Specifications: Engineered with a 28.6 mm steerer clamp diameter, a 31.8 mm barbore, and a 44 mm stack height for seamless compatibility with modern bike setups.

Applications & Performance

1. Enhanced Comfort & Control: Weighing just 435 g (for the 85 mm extension), this patented RA200 suspension stem significantly cushions impacts, making it ideal for gravel grinding, cross-country mountain biking, and long-distance trekking.
