[Closed] gear indexing.

Middle cog at the front, then set the limit screws at the back, then adjust the indexing. Put it in the middle of the cassette, and do the same for the front mech.

I guess its right up the late greatr sheldon browns street the http://sheldonbrown.com/derailer-adjustment.html

I always have it on middle chain ring, put it to the samllest at the back, put the barrel adjuster to about half way, undo the cable, set the limit screw, tighten up the cable(pull the cable hand tight) switch up the gears to the biggest at the back and set that limit screw. bingo gears sorted, maybe just need to adjust at the barrel a wee bit while out and about or after a while to adjust for cable stretch..

If that doesn't work properly, something else is causing problems.

thanks guys,

i have a slx rear mech but it doesnt have the barrel adjuster on it,only has one on the shifters there slx too,does this matter??

no - just use the one at the shifters instead of at the mech

No. Only one adjuster is required.

thanks for your fast input.will have a go when the weather clears a bit.can this be done without a bikestand??

Tips include setting the limit screws before connecting the cable. Wind in your shifter barrel to almost right in to the shifter (your new cable will stretch so this gives you good room for adjustment on the fly later on). Start on smallest cog rear. Pull the slack through with a good pull and you will almost always have nothing else to do if your mech/hanger are straight. Adjust the B tension screw on mech to get the wheels close up to the cassette without fouling.

Mechanic told me to shift once then rotate the cranks to test each shift up and down the range to see where the issues were instead of spinning constantly and shifting up and down the range. Has always worked very well for me. For double/triple shifts you want to keep it spinning.
