1.Highquality materials: this bicycle chain guard is made of highquality silicone, which has excellent elasticity and tear resistance. It can withstand continuous vibrations and shocks while driving without being easily damaged. And this material has good friction, which ensures that the bicycle chain protector sits firmly on the frame even in harsh driving conditions. 2.Airbag design: this chainstay protection MTB has an airbag structure design. Compared to conventional flat chain guards, the airbag structure can form an additional buffer layer between the chain and the frame. The airbag frame protection bicycle can not only prevent damage to the frame, but also slow down the loss of the chain and the associated transmission parts and extend the total life of the bike. 3.Easy to install: clean the surface of the lower fork chain side before using this airbag bicycle frame protector. After the surface of the lower fork chain side has completely dried, peel off the protective film on the back of the chain protector mountain bike, then align the bicycle chain protector to the area to be protected and stick it on. After sticking, you need to apply a certain pressure to ensure it is firmly in place. 4.Smooth driving: the air bag frame protector MTB can release some energy under pressure, which helps to reduce vibration transmission while driving and improve driving comfort. The airbag bicycle protection can significantly reduce the noise generated by the collision between the chain and frame by absorbing the impact force created when swinging the chain, making driving quieter and you have a good driving experience.
