Product information "S-TECH BLADDER-KIT WP 71MM - BLACK"
The S-TECH Bladder Kits are designed to optimize WP shock absorbers. Unlike the piston design of the stock bladder kit, the S-TECH bladder kit has a rubber diaphragm to separate the nitrogen and oil, making it completely free of friction loss and frictional heat.
The expansion tank is made of high quality 7075 aircraft grade aluminum. The reservoir has extra fins to increase surface area, improving cooling performance.
The coating on the inner and outer surfaces provides optimum protection against wear. In addition, enlarged wall thicknesses in the rim area ensure very high stability of the tank.
Advantages
