Why is my bike gear skipping?
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. To fix a skip in the rear derailleur, shift your chain into the smallest ring on your rear cassette (the hardest gear) and the middle or larger ring on your front derailleur.
How do I stop my gears from clicking?
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.
Why does my bike make noise in certain gears?
When using both large rings you risk the chain rubbing on the front derailleur and the rear one could be pulled tight enough to cause some catching too. When on both small rings the rear derailleur can fold right back and cause the to jockey wheel to catch on the chain as it runs underneath.
What should I do if my Shimano gears make no noise?
If the chain shifts to the third smallest sprocket, turn the adjuster clockwise until the chain returns to the second sprocket. If no noise is heard at all, turn the adjuster anti-clockwise until the chain hits the third sprocket and makes a noise.
What to do when your bike won’t shift up a gear?
If the problem with your bike is that the chain won’t shift down when you lower your gears, turn the cable adjuster clockwise to loosen it. If you’re having the opposite problem and your bike won’t shift up when you go up a gear, tighten the cable adjuster by turning it counter clockwise.
Why are my gears not indexing on my bike?
Indexing problems can be caused by cable stretch, which is a normal part of the bedding-in process for new bikes or cables. Check that a bent or damaged rear derailleur isn’t to blame first. If it’s all good, here’s how to index or re-index your gears.
Why are the gears on my bike not shifting?
The gear refusing to shift is the most common problem with a very simple solution – indexing. When indexed properly, the gears shift one after the other with ease. If you are skipping gears and facing problems, the indexing is to blame.
If the chain shifts to the third smallest sprocket, turn the adjuster clockwise until the chain returns to the second sprocket. If no noise is heard at all, turn the adjuster anti-clockwise until the chain hits the third sprocket and makes a noise.
Why does my bike make a rattle when I Shift?
Another common cause is loose cassette cogs, which create a drivetrain rattle, sometimes accompanied by poor shifting. Solution: Feel for play by trying to move the cogs laterally with your fingers. Use a Shimano cassette lockring tool and a large adjustable wrench to tighten Shimano cassettes by tightening the lockring (photo).
How often do you change gears on a bike?
Go up every gear once and down every gear once. Note places where the gears have trouble shifting, where the chain slips off the gear, or where you need to shift twice to make the bike shift. While testing one derailleur, put the other one in the middle gear.
