2pairs ZTTO Mountain Bike Shock Absorbent Fork Oil Dustproof Sponge Ring, 30mm, 32mm, 34mm, 35mm, 36mm, 38mm, 40mm

1. Material: sponge
2. The sponge is made through a 5 times heat compression process, which produces a high density sponge, i.e. oil and solvents, which ensures the durability and longevity of the forks
3. Seamless cut: unlike traditional cuts, this sponge is non-modular with no seams and a tolerance rate of less than 0.1, ensuring a snug fit and excellent performance
4. The use of sponge improves the forks damping ability, resulting in a smoother, more comfortable ride with less vibration and impact on the arms and hands
5. The sponge ring is compatible with a wide range of bikes, including mountain bikes, road bikes and folding bikes, which makes it a versatile choice for different preferences and needs
6. The sponge makes it easy to visually inspect the condition of the fork: dry sponge indicates oil loss and dry friction between the inner and outer tubes of the shock, which should be lubricated; the sponge produces black sludge, which indicates increased metal wear and serious lack of maintenance of the shock; the sponge is covered with sand and dirt, which indicates a loss of sealing of the oil seals, which should be replaced immediately
7. Specifications: 30/32/34/35/36/38/40mm
