Mountain Bike Air Fork Bicycle Suspension 26/27.5/29 Inch Straight/Tapered Tube

  
Upper Tube Material: Aluminium, low friction anodised, 32mm. Steerer Diameter: 1.1/8" - 1.5" Tapered; 1.1/8 Straight. Fork Travel: 100mm (120mm refers to the exposed stroke And 100mm is the actual active stroke). The easy set up covers all rider weights and features simple air pressure charts on the back of forks. Measurement gradients indicating the current sag and travel settings are conveniently located on the upper tubes so that you always know how much travel you are running. Note: The position of O-ring indicates the sag percentage. The Lockout setting prevents the fork from compressing until significant impact occurs. When the lockout adjuster knob is in the open position the suspension fork is able to compress quickly and freely through its full range of travel. When the lockout adjuster knob is in the lock position the suspension fork will resist compressing into its travel until significant bump impact or downward force occurs. To activate lockout mode, rotate the adjuster knob clockwise until it stops.

To deactivate lockout mode, rotate the adjuster knob counter-clockwise. Manual Lockout:rotate the lever to lock and unlock the compression damper. Remote Adjust:Lockout on forks equipped with a remote can be actuated with the handlebar mounted remote at any time during use. Aluminum upper tubes provide stiff performance;Magnesium lower tube help keep weight down.

The size of the actual measurement. It is a normal phenomenon. During the assembly process of fork, the steerer tube needs to squeeze the crown, so that the part becomes white.
