I know you love these threads, so apologies in advance for the horribly dubious explanation.
So before I start throwing bricks at my bike, a little help please. Bike was built at the start of summer Sram Gx/sunrace 11-46 cassette with new cable/inners and I've repleaced the jockey wheels with hope ones as they seized.
In the lowest/smallest gear the click on the shifter seems to become 'vague/soft/random' it's as though if there isn't enough cable tension to make a positive change on the shifter and consistently you wind on tension its wont' come back down and the rest of the shifting goes to hell. Otherwise shifting is great up and down the cassette, limit screws are set fine but i can't get the whole shebang to work properly.
So its either..
Sticky innner/outers, even though its full length and only a few months use
Derailleur hanger alignment - could be but 'looks straight' and shifting is fine elsewhere.
Something is wrong with the Shifter.
?
Edit: should be highest/smallest gear, you knew what i meant.
