Derailleurs Bike Gears


Recommended Posts

I brought my young lad a Bicycle last xmas which he has only now reached the age to ride on the Road, I took him for a cycle ride yesterday and he kept complaining about the gears clicking and not changing! it seems that when he selects 1st it holds it for a while and then clicks back into 2cnd, the bloody chain also comes off when he pedals backwards :hmm:.

 

I have looked on the Net but can't get my head round it with so many things cropping up here at the moment, can anyone please give me a easy straight forward idiots guide to how I can adjust these gears? I tried adjusting some cables but have no idea weather I'm turing them the right way or not :whistle:....

 

Cheers in advance

if its indexed gears try the indexing adjustment knob, at the top of the cable towards the shifer end. if you get no joy with that try adjusting the 2 screws on the back of the derailer marked h and l. h for high gears l for low. if the chain will not move up into the bigger rings turn the l screw anticlockwise. just 1/4 of a turn or so at first and keep going out slowly till you get a result. which way is the chain falling off....towards the spokes or pedals??

Like Maty says, the two nuts on the deraileur are for fine tuning. Try and get the rear wheel off the ground and crank it round by the pedals, as you do, turn either of the screws. It'll become obvious which one you should be turning after a short while. As you turn the screw you will be able to hear and see the chain sitting onto the right cog. If the bike has two (or three) chainwheels on the front, ditto with that changer too.

If all else fails Jasper, get the lad a stick and hoop :big_boss: never did me any harm and they don't get punctures :D

 

Nice one Nelson :clapper:

 

He's played with one of them for years after I got him one for xmas! He's been a bit spoilt to be Honest mate having a stick and a hoop plus the lucky boy has some Marbles to play with along the paths and gutters, the lads at his school are jealouse as f**k ;)

 

Many thanks lads for the help! I'll get his bike sorted when I can next engage my brain, at the moment I feel like someone has stuck a electric mixer in my skull and gave it a good wisk, everything that could have gone wrong probably has in the last couple of weeks :cry:...

 

Cheers
