Lightweight hi-end BMX rear hub. 9T driver with patented Q-Lai (Q-Lite) drive transmission technology with 6 double independent pawls located in the hub body. This makes more space inside the driver for the three bearings. Together with two bearings in the body this makes our Razor a really smooth rolling and strong hub. 15mm Cr-Mo steel inner axle machined to 14mm diameter on both ends. Female hollow 3/8” bolts made of Cr-Mo steel (for 17mm wrench or 8mm Allen key). Hub body made of 6061 aluminium. Both push-in cones made of 7075 aluminium. For grinding it is the best to use optional solid bolts. Possible weight reduction when using optional 7075 aluminium axle.
