Chain Keeps coming OFF! on HARD Initial Pedaling.........need a fix
What's up guys, riders and enthusiasts!
I am having this dilemma I need to fix.
It's racking my brain upside down and sideways.
Here's the Diagnosis for those that have encountered or
had resolved this issue in the past.
* My setup is 50/34T with 11-34T cassettte.
* I have this setup with ALL 11 speed groupset.
Front der., Rear long cage der,, 11 speed chain, 11 speed Dura Ace 9000 Crankset 50/34T & 9000 levers.
* Recently had a crash, noticed a rear der. scrape, nothing serious.
* Looking from top to bottom the pulleys look slightly misaligned. (1st and 2nd largest cog)
* Shifts smoothly on ALL gears (however) noticed when reverse pedaling on ONLY
the 1st & 2nd LARGEST cog on the big ring it shifts back down to the 3rd cog. But shifts right back to
the 1st cog when pedaling forward.
BUT, when on the 3rd cog reverse pedaling is normal (no skipping)
* Did a hard pressing on the big ring 2nd largest cog & the chain came OFF
causing me to crash at a light intersection. Kinda a scary moment.
Can this be a bent skewer or rear wheel not being tight enough? I noticed it came loose on
the recent fall, BUT, did a super hard squeeze today and it happened again! But rear wheels seems
tight and secure.
I am narrowing this down to the rear derailleur needing to be replaced?
Any thoughts, confirmation to this? The pulleys does seem to wiggle from side to side.
Chain too short? Also, noticed this happening on my 2 other bikes.
ANY comments, rants or clues appreciated.
