Need some help people recently built my 1st bike and having bother with gears. So I admitted defeat and took it to my local bike shop who adjusted them up perfect. I did about 20miles on I and once again they needed adjusting which is fair as there all new cables etc. So took it back again they adjusted them for free been out today and there worse than ever clicking, jumping. Has anybody got any guides or booked to buy so I can learn how to adjust them as I’m sick of trapsing back to shop…
Any help
Tom

There is lots of videos on youtube bud but if they’re jumping it might be worn components. How old is your chain/chainrings/cassette?

Assuming brand new components due to new build? That being the case. Should just need to set the bottom limit screw before attaching the cable. Then hook up the cable taking up as much slack as you can and wind out the barrel on the shifter a touch to take up the rest. Done!

PS.this should be done with the shifter in smallest gear for both front and rear.

Loads online but the best method I’ve used is cable disconnected, set high and low limit properly then barrel adjuster to the middle reconnect cable

If by any chance you’re in Nottingham I’ll have a look for you.

its not a mystic science but sometimes can be frustrating – beer helps for me

Hi Peoples
its all new componenets nd it wont have done 40miles so hopefully nothing worn yet.
I will go and invest in some beer and watch some videos, its something ive always wanted to have ago at like. Ive mastered everything else on the bike just gear grrr.
How do i no were to set high and low limit screws?
when you say wind the adjuster to the middle you mean on shifters them selves?

its the fear of the unkown i guess haha

The bottom adjuster should sit the chain on the smallest gear. The cable should be just about to take tension in this position. I’d set correctly then the top screw is largely redundant apart from stopping you push the chain into the spokes.
