This is a 20-inch (406) bicycle wheel set for mountain bikes with six-bolt disc brakes. It has a double-layer aluminum alloy rim with a rim height of 21 mm. The rim is anodized black with a CNC-machined edge and a laser-engraved PASAK logo.
The hubs are made of 7075 aviation aluminum with imported super-lubricated bearings. The front hub has two bearings and the rear hub has four. The rear hub is designed for tool-free disassembly, so the freehub body can be maintained and lubricated without tools.
The freehub has a 7075 cold-forged six-claw design with independent pawl springs. It supports 7-, 8-, 9-, 10-, 11- and 12-speed cassettes. Each wheel has 24 spokes made of 45# steel round bar with 14 mm anti-rust copper heads. Quick releases and rim tape come with the wheel set.
