cheers

Yes, on park tools website0

Assuming the gears worked together previously (i.e you havent just changed one of the components) then one cause of this type of problem is the cable sticking in the outer casing. This is often overlooked. The gears index in one direction when the cable is under tension but not in the other direction when the spring in the derailleur is moving the chain over the cassette.

It's all fine it's just the screw Adjusting bit I can't gerWhen i die I just hope the wife doesn't sell my stuff for what I told her I paid for it other wise someone will be getting a mega deal!!!

Just keep in mind the limit screws do nothing for indexing. On a normal mech the mech rests on the lower limit, and is stopped by the upper limit screw from allowing the chain to go over the top of the big cog.0

so what were you trying to fix?
and what have you now tried to adjust?"Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

Trying to set it up so I can use all my gears at the moment I can use the small ring on the front and the middle one but it won't move up to the big ring and on the rear its fine till it gets to 7 then jumps to 9 and same on the way back upWhen i die I just hope the wife doesn't sell my stuff for what I told her I paid for it other wise someone will be getting a mega deal!!!

I have played with the adjusting screws front and rear and twisted the tennison screws on the shiftersWhen i die I just hope the wife doesn't sell my stuff for what I told her I paid for it other wise someone will be getting a mega deal!!!

First thing is first. If you want to do it from scratch, you need to unclamp/remove the gear cable and maybe get a new one. New inner and outer for smooth shifting would be a good idea. Removing the chain is also a good idea to make sure the index screws are set properly.
Shift the shifter into the highest gear (smallest cog). Use the high index screw on the mech to make sure the jockey wheel on the mech is sitting right under the smallest cog. Push the mech by hand up to the biggest cog, and use the low index screw to make sure the jockey wheel is sitting right under the biggest cog, or maybe a little further over towards the spokes (only about 1mm), just for good measure.
THEN install the chain, pedal the bike so that the chain and mech are sitting on the smallest cog (highest gear). THEN install the cable, making sure the cable is tight, but not so tight that you're pulling it up another gear, and also making sure that the barrel adjuster on the shifter is wound out a couple of turns before you clamp the cable in the mech.
Spin the cranks and shift up and down the gears to see how they work. You may need to adjust the cable tension using the barrel adjuster on the shifter. Wind it out to increase the tension, wind it in to decrease. If the mech is not shifting up properly in some gears, this means you need a bit more cable tension. If it isn't shifting down properly in some gears, this means you need a little less cable tension. Sometimes the cables stretch after a bit of use, this means you just need to increase the cable tension a touch. Only ever increase or decrease the tension by small amounts (half a turn at a time). A little goes a long way.
If you follow those instructions to the word, you can't go wrong. Once you've done it a couple of times, it really is second nature.0 -
Thank you very muchWhen i die I just hope the wife doesn't sell my stuff for what I told her I paid for it other wise someone will be getting a mega deal!!!

Sorry I got this bit mixed up. If it's not shifting DOWN properly, you need more cable tension (as the mech requires the cable pulling through to shift down to the easier gears). If it's not shifting UP properly, you need less cable tension (the mech pulls up through to the higher gears using the spring in the cage, the down shift just releases enough cable to let the spring pull the mech up/out a bit more). I know it sounds confusing, but once you've gotten your head around how the mech and shifter work (it really is very simple once you realise), it'll just click in your head.If the mech is not shifting up properly in some gears, this means you need a bit more cable tension. If it isn't shifting down properly in some gears, this means you need a little less cable tension.0 -
Once the limit screws are set they should never need adjusted. I've seen so many spokes ruined by people "setting" their gears!0
