Gear slipping
Hi
I have had my current bike for 8 months, and the gears slip a little bit on occasions. If I put off getting this fixed, will the problem become more expensive to fix later? |

You probably just need to adjust the gear cable tension a bit. There should be a knurled knob where the cable joins the der. Select one of the middle gears and twist the cable tension knob and you'll see the mech move in or out a bit. Try to get it to line up nicely on the cog. Go for a little test ride and fiddle around with the tension until it changes nicely and doesn't slip. There may also be a gear cable adjuster at the front of the bike that can be adjusted while riding along. Rear and front adjusters do the same thing. One of the adjusters probably just needs a quarter to half a turn. If the chain is reluctant to shift to the next largest sprocket, turn the adjuster anti-clockwise to tighten the cable, and vice versa. Alternatively, if you've done a lot of miles your chain might be worn out. See http://www.sheldonbrown.com/chains.html#wear If the chain is very worn you'll have to change the chainrings and cassette too, but it isn't a huge expense or difficult job. You don't always have to change the chainrings too; they tend to last longer. If the chain is worn out, first of all try just replacing the chain and cassette. ~PB |

On a dearailleur there are two principal causes of slip. 1) chain not in gear - effectively running in the gap between two sprockets. 2) worn chain and/or wrong sprockets case 1) AFAIK won't get worse, cost of fix constant. case 2) will get worse over time. If the problem is (at the moment) SOLELY a worn chain, the cost will increase, since a worn chain damages chain rings and sprockets. If the cause is SOLELY a worn chain the fix is a new chain, which is cheap. If the cause is worn chain AND sprockets, again the cost is already "maxed" since the cure is replacement. BugBear |

As other have said they may just need adjusting which you can do by hand with no tools, but there are loads of reasons why the gears are slipping. If your bike has seen some filth (e.g. used in wet/muddy conditions) and if you have small cogs they could also be full of crud. Running a screwdriver between the bottom few cogs will scrape some of this out. This assumes you have derailleur gears, if you have hub gears which are slipping it could be something serious (but unlikely) or it could be something simple like the wheel not being straight which is easy to fix. On my bike there's an unusual problem where the chain sometimes skips and the chain appears kinked as it goes around in certain gears. When I work out what this is and how to fix I'll let you know! peter |

That'll be a stiff link. Never had one myself, but apparently you can sort them out by flexing the chain sideways where the stiffness occurs. A bit of oil at that point would probably help too. |

Cheers for the tip of - that was one of my suspicions. I have 2 powerlinks in the chain (as i cut the chain a bit short first time!) and 1 is always difficult to undo and clip together again so I think it needs replacing and throwing out. peter |

Easy check for a stiff link is to lift the back wheel off the ground a turn the pedals backwards. |
