I am setting up a tourer ( this https://www.biketart.com/bikes-c1/frames-c33/ridgeback-panorama-deluxe-frameset-p12171) and having a nightmare getting my head around the gears.
I am not a first timer, but also not an expert!
Gear shifters are 9 speed Sora triple. I haven't got to the front yet, just the back!
This set of levers http://www.highonbikes.com/shimano-sora-r3000-sti-gear-brake-levers-9-speed-triple.html
The cassette is 12-32, shimano brand. XT hub
The rear mech is https://www.sjscycles.co.uk/deraill...ed-shadowplus-rear-derailleur-black-sgs-cage/ - bizzarely does not have a barrel adjuster.I do have a barrel adjuster on the downtube (one mounted on the frame) but fiddly to use
Process so far is to set the H and L stops by eye (without cables in place) and pushing the mech it swings in and out fine so the jockey wheels are aligned
I then installed the cables, got tension approx right with chain on smallest sprocket, but when I run through the gears the mech only moves up to the 3rd sprocket. Almost as if the STI lever is moving the mech in smaller increments than needed (e.g. if the mech needs to move 3mm per cog it is only moving 2mm so ends up not moving into the biggest cogs).
Am I missing something fundamental here, have I got a mismatch of kit, and can anyone HELP!! I have the phone set to loud, so your postings will ping in very fast!
In case it helps (can't see it will) FYI the chain is on without having been cut to size yet.....
