Front wheel 2 bearings, rear wheel 4 bearings, with a Japanese bearing structure, have far superior performance compared to ballwheel sets and ordinary 2-speed, 4-speed wheel sets. They rotate more smoothly and have a smoother and louder sound. The flowerdrum is a quick disassembly type, making disassembly and maintenance very convenient.
Rim insertion and docking design with Liuding, with double-layer rims, effectively protecting the inner tire and increasing the tensile strength of the wheel set Forged aluminum alloy quick release, high-pressure nylon tire pad, can withstand more than ten times the pressure compared to ordinary tire pads, providing 100% protection for the inner tube. The original factory cardboard box is individually packaged, with a much thicker thickness than the general wheel group cardboard box, which is hard enough to ensure the transportation safety of the wheel group.
Wheel set usage conditions: size matching (such as the original 20 inch now also needs to use 20 inches), crotch matching (i.e.the distance between the front and rear axles must be the same to fit), 7-11 speed cartridge flywheel Please note a few points:
1. 100/135 and 74/130 refer to the opening of the front and rear wheels;
2.406 is the standard 20 inches, while 451 is one circle larger than 20 inches;
3.The 100/135 wheel sets are all disc V dual-purpose, and the 74/130 wheel sets only use V (C) brakes (because the flower drum doesnot have a disc brake hole);
4.There is a difference in the shape between the 74/130 flower drum and the 100/135 flower drum. If you have any questions about the above instructions, you can contact customer service for consultation.
