My wifes bike has really old Sram Xray grip shifters, like 1995 or so. Just replaced the cables and now, in the biggest gear, on the cassette, under pedaling pressure is skips. Tried to adjust it out with travel screws and barrel adjustments. No luck. Pedal up a steep hill and skippy skippy skip....
Did we put the shifter back together wrong? It works great other than skipping on the biggest gear under pressure.
Not finding any diagrams on the web for these shifters either.
