Proform 320 SPX Indoor Bike Adjustment Knob
This replacement Proform 320 SPX indoor bike adjustment knob is used to alter the seat and handlebar positions on this indoor bike.
For effective exercise, the seat should be at the correct height for you. As you pedal, there should be a slight bend in your knees when the pedals are at the lowest position. To adjust the height of the seat post, loosen the adjustment knob and pull it outward. Then, move the seat post up or down, release the adjustment knob into an adjustment hole in the seat post, then firmly tighten the adjustment knob.
Use the same method to adjust the horizontal position of the seat exept move forwards and backwards. The same method is used to adjust the handlebars up and down.
Always make sure that the adjustment knob is engaged in an adjustment hole.
Please note this item may have very light cosmetic marks.
