Adjusting the trigger pull on Shimano STX shifters?
August 23, 2014 1:00 AM Subscribe
I just put some new ergonomic grips on my mountain bike, and they're slightly thicker rubber than the older ones. The tiny bit of extra circumference now obstructs the pull of my trigger shifter. When I try to go into a higher gear there's not enough clearance for the trigger to engage the ratchet in the shifter and move the dérailleur. I can force it if I squeeze hard enough and push the lever back out, and the bike shifts gears fine, so the issue is not
cable tension. My question: Is there a way to adjust the trigger pull to be slightly further away from the handlebars?

I'm rocking some vintage Shimano STX shifters
. They're in pretty good condition, and up until I put the new grips on worked a charm. I'd like to see if there's a way to adjust the levers so that the trigger pull (which I use my index finger to activate) is a millimeter or two further away from the handlebars to begin with.
There's a nut on the bottom of the unit
that looks like I could loosen it and the trigger-pull and thumb-push levers could be rotated closer together or further apart. But I'm scared to mess around with it without knowing what will happen when I loosen the nut. I can't have the entire assembly falling to pieces on me right now.
I'm taking this bike out on an extended series of rides next week, so I'm kind of short on time. Otherwise I'd be taking this to good ol' LBS at my leisure.
