The evolution of bicycle frames has a colourful history. Initially, the Bike frame was made of wood and iron, bulky but sturdy, and bicycles were used more as a means of transport. As technology developed, iron and aluminium frames appeared, which were lighter and more durable, and bikes started to become people's sporting companions. In recent years, more and more different models have appeared, such as road bikes, BMX bikes, fixed gear bikes, folding bikes and so on. The popularity of carbon fibre frames has made bicycles lighter and faster, promoting the development of cycling. However, due to the high price, it is not yet the mainstream of the market.
We mainly provide the 700C bike frame in aluminium alloy and Cr-Mo steel for fixed gear bike and road bike. Each material has its own special features. We also have the BMX frame, it's a different style but popular and it is a very challenging project. The freestyle frame has a big difference from other bikes, it looks smaller and shorter, riders use this bike to play the BMX flatland. They are usually made of Cr-Mo for considering the necessity of the strength. We provide the frame customization service, welcome to contact us for more information.

The Y43X-10T proportional pressure reducing valve made in our factory has beautiful appearance, reliable quality, correct proportion, stable operation, both reducing dynamic pressure and reducing static pressure.
The valve acts on the pressure difference between the two ends of the piston inside the valve body, and changes the pressure after the valve to achieve the purpose of reducing pressure.
The decompression ratio of the pressure reducing valve in our plant is 2:1, 3:1, 4:1, 3:2, 5:2, etc., and also can design a special proportion of pressure reducing valve according to the user's requirements.
