If you are thinking where my post about adjusting front derailleurs might be, it’s not. It’s not a thing anymore, well with mountain bikes. Road bikes will continue to use this antiquated technology until it finally arrives at the bitter end of a dark tunnel.
Step 1: Take your bike to your local bike shop.
If you are more persistent and have read on, then my instructions are below. You will find a video link attached in a few weeks.
- Make sure that the derailleur hanger is straight (if you don’t know what this is then repeat the above “step 1”)
- Disconnect the derailleur cable (for non-electric systems)
- Now dial in your high and low limits by physically pushing the derailleur to the low and high cogs; gently! Adjust your H and L screws so that the chain makes no strange or shifting sounds in those two cogs
- Back off all barrel adjusters associated with this system
- Attach your derailleur cable to the derailleur using the pinch bolt (gum or duct-tape attachments that work get a star) in the default (usually high) position (Hint: XTR, XT, XX1, X01 and similar derailleurs typically like a little cable slack, maybe 2mm from the tight position at the pinch bolt)
- Begin shifting while pedaling the system
- Make necessary barrel adjustments to adjust tension on the cable if the shift isn’t quite right
- Listen to each gear as the chain rides over it; no sounds should emanate that aren’t simply the normal chain and cog interface
I promise a video to explain all this and make it easier to follow. But for now if you’re desperate then just take it to a shop and pay the $15 to get it done right.
