KEY TECHNOLOGY
Freehub fit with 3 pawls and 9 teeth ratchet
The patented pawl design with 3 pawls and 9 teeth allows each tooth to fit closely and make close occlusal contact with the 48 teeth surface in the ratchet ring when turning. The design of pawl with 3 pawls and 9 teeth steps is more effort-saving when pedaling.
Butt welding
The alloy rim of Hubsmith wheel is built by high-end butt welding technology to largely enhance the stiffness of the wheels.
Precision bearings
Precision bearings provide riders with a smoother road cruise.
Hand-built wheels
Using precise measuring equipment and specialized tool, our technicians adjust and correct lateral and radial deviation and center the rim.
Heat-Treatment
Heat treatment to alloy rim makes the hardness of material more rigid.
Special drilling angle
To drill the holes with proper angles in precise calculation for mini wheels can optimize the spokes to be built in straight lines.
Sand-Blasting
Mini alloy wheel sets will have been through sand-blast surface treatment to enhance the brakeage of the brake.
