I have a 2006 Specialized Comp XC running probably its original Shimano Deore RapidFire click shifters.
The rear shifter is jammed up, can't downshift anymore (won't "click"), probably gummed up and not responding to opening up spraying and lubing.
I should probably just replace, but having trouble making sense of what replacement will fit a bike this old.
