How do I tighten my bike gear cable?

Which way tightens gear cable?

This rule will help you remember which way to turn it: If the derailleur is hesitating when shifting toward the spokes (the more common problem), turn the barrel toward the spokes (counter-clockwise); and if it hesitates shifting away from the spokes, turn the adjuster away (clockwise) from the spokes.

How tight should shifter cable be?

Holding the cable tightly so it can’t slip, pull up with the pliers to remove all slack in the cable and hold it like this as you tighten the anchor bolt to secure the cable in place. It should now be tight enough so that when shifted onto the large chainring, there’s no rubbing.

How do you tighten a loose gear bike?

-Turn your barrel adjuster at the shifter 1/3 to 2/3 of the way out . -Loosen the pinch bolt on the derailleur, pull all the slack out (make sure cable housings are fully seated in their stops), and re-tighten the pinch bolt. -Use the barrel adjuster to fine tune any tension issues.

How do you tension a front derailleur cable?

Begin with the chain on the smallest cog. Relax the cable tension completely using the cable barrel adjuster. Place a hand on the derailleur body to feel for any lateral motion, and select one screw to turn one full turn clockwise and then counter-clockwise. If you felt motion in the derailleur, this is the “L” screw.

How do you adjust tension on a derailleur?

Adjust the cable tension

Use the barrel adjuster to fine-tune its position. Turning the adjuster anticlockwise increases tension on the cable, bringing the derailleur closer to the wheel. Clockwise decreases the tension, moving it back towards the frame.

Should my derailleur cable be tight?

You need to pull it pretty tight before clamping it to the derailleur. Probably as tight as you can. Usually I find that’s still not tight enough, so I screw the barrel adjuster down all the way before putting the cable in and then open it up until the tension is correct.

Where is cable tension maximum?

This equation also shows that the maximum tension occurs at the end supports, that is at x = 0 and x = L , which is also where the slope of the cable is maximum. The minimum tension occurs at the mid-span and is equal to H .

Can a derailleur cable be too tight?

Shift down to the smallest cog and do the same using the other adjustment screw on the back of the derailleur. 5) Again shift to 2nd gear and check the pulley alignment and then shift to the 8th cog and make sure it lines up well there too. Make any fine adjustments you can see are necessary.
