Why does my chain slip when I pedal hard?
Most of the time, a skipping chain is caused by cable stretch. In the first half dozen rides on a new bike your shift cables stretch the most. They can also stretch over time as you ride. Hippley explains, “It takes cable tension to open a derailleur, which shifts your chain between gears.
How do I adjust the tension on my derailleur?
Adjust the cable tension 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. If the chain seems hesitant to shift up, increase the cable tension by turning the barrel adjuster anticlockwise.
Why does my rear derailleur click?
A clicking noise often comes from your chain wanting to jump up or down a gear on the rear cassette. This can typically be fixed by adjusting the tension of the cable that runs from your shifter to your rear derailleur. The clicking could be caused by a bent derailleur hanger.
Why is my derailleur hitting my spokes?
It is possibly bent/tweaked and the only way to know for sure is to put an adjustment/alignment tool on it and check. If it is it is generally and easy tweak to put it back in alignment, then realign/adjust your rear derailleur.
What does the B screw do on a rear derailleur?
1 Answer. The B – screw controls the body angle of the derailleur. It pulls the pulleys away from the sprockets, so you don’t rub against them. If you set it in the largest rear cog (as you should), when you’re adequately clear, you don’t have rubbing.
