Campy 10sp Bar end shifters won't Index
I cannot get my Campy 10sp Bar End Shifter to index properly. The upper & lower limits are set correctly. When it's indexed correctly for the large spockets, it shifts straight from the 13 to 11 when down shifting, missing the 12 cog despite there being 1 click left on the shifter. If it's indexed so it shifts correctly on the small cogs, then when I get near the 19, then it starts over shifting upwards missing the 21 & jumping straight on the 23. New cables, chain & sprockets that have been used together. Happens in the 39 or the 53.
