Axle System: Thru-axle is a wheel mounting system. RWS technology from DT Swiss gives quick, precise mounting by turning an easily adjustable lever. The Thru-axle systems guarantee a rigid and secure connection between the wheel and frame. Check compatibility with the frame and fork for built-in-width, diameter, and thread of the axle, defined by the frame and fork manufacturer.

Brake Interface: Disc IS (6-bolt) (abv. for International Standard). The disc brake is mounted via 6 individual screws on the hub. In the event of a repair on the trail, no special tool is needed for disassembly, most MiniTool’s have a T25 Torx for disassembly of the six screws.

Built-In Dimension: 148mm Boost refers to wider axle dimensions. Frame and fork manufacturers use this to build a stiffer bike overall. Use a flatter spoke angle on the wheel to increase flange distance. This will improve symmetry and increase stiffness on large wheels.

Spoke Interface: Jbend Classic is a traditional type of spoke. Characterized by the 90-degree bend in the spoke head at one end, resembling the letter J.
