... Lightweight Design--FASTACE is a lightweight spring damper designed and manufactured for fast downhill bikes. Its inner and outer tubes, upper and lower plates, left and right legs are made of aluminum alloy with high strength and light weight, and the interior is designed with spring and oil pressure damping..
Hydraulic Damping System--The hydraulic damping system is inside the front fork right tube, that is, damping force generated by reciprocating motion of piston and valve plate in hydraulic oil is used to suppress vibration and impact caused by acceleration and deceleration of vehicles and road bumps. The internal damper adopts wear-resistant, low freezing point,special oil for high quality shock absorber to ensure the damping stability and reliability..
⭐⭐Alloy Steel Spring Design--High strength alloy steel spring design is used inside the front suspension left tube, which can reduce weight and support the rider's weight compared with the conventional spring, so as to meet the various needs of your daily riding..
Multi Function--200mm travel, for MTB bicycle wheels, 26/27.5/29 -inch beach bike/s....

This belt assures accurate belt tension, alliance and damping which considerably enhances performance..
With the help of vibration damping system, it increases tension and keeps the amount of energy reduced to a natural frequency for lasting use.
Torsional round spring design causes consistent tension and helps in preventing the contamination. This ensures high durability.
Provides a complete range coverage for domestic applications and those that are imported or heavy-duty.
