kona stab gear advice

[333337lee]

1999 Kona stab purchased from the forums a few months ago

I have read into gear adjustment but beyond the 3rd cog on the rear the chain skips and rarely settles.
I tried the adjusters and can't get it right.

the shimano sl-m570 shifter clicks 7 times so I was thinking it's an 8 speed

the deraileur is a shimano rd-m750 and I can't get it to shift to the smallest cog

the rear cogs are 9 speed

is there a mismatch?

when I search for sl-m570 it usually comes up as a 9 speed shifter.

The shifter and mech are both 9 speed items, so should work fine together. It won't shift into the bottom cog either because the cable slack is insufficent or the mech is set not to move that far. Slacken the adjusters alll the way off (screw in) and shift to the smallest cog. If this doesn't work, undo the screw marked 'H' on the rear mech half a turn and try shifting again. Keep undoing half or quarter of a turn until it shifts.

When the chain is in the largest sprocket, the jockey wheel should be paralled with the cog, increase or decrease the cable tension until this is the case. Once you've got this far then fine-tune, turning the cable adjusters quarter of a turn at a time to adjust the shifting. Too much cable tension and it won't move into a larger sprocket quickly. If you get the indexing correct and the shifting is fine with no load on the chain, and then when you ride it you still have problems, your cassette may be worn out.

Before you start all these shenanigans, you might want to take the gear cables off and squirt WD40 or similar down them to aid smooth shifting.

Problem

Just took the wheel off because the freewheel is loose I have taken off the cogs and the cassette wobbles quite a bit more than any of my other bikes can this be tightened?

by cassette do you mean the splined freehub that the cogs slide onto? you can tighten the freehub with a 10mm allen key if you take the axle - they don't go loose very often tho - might as well clean and regrease everything while you're at it :?

still learning

Thanks I never new they came apart. I threw away a wheel a while ago because the freehub was loose and I thought it wasn't serviceable.

Sorted

Thanks for the advice I used a shimano freehub from a wheel that I got from the dump a while ago all working well now. just cost me £4 for an Allen key set as I didn't have a 10 mm
