Looking for some equipment adjustment help

Hey All!

Since the world is sadly at a standstill here in NYC, all the bike shops have shut down. I'm having some trouble with the front derailleur and am hoping someone is willing to help solve the issue.

My front derailleur won't shift to the largest sprocket. I've tried basically resetting and starting from scratch and no luck. Adjusted tension, the position of the derailleur, the upper and lower limits and nada. The tension is incredibly tight to even get it to shift out of low and it still only goes to the middle gear. At the same time, the STI feels like it's not really working properly either. Video below.

The front derailleur is such a straightforward setup that I really can't figure out what's going wrong unless the STI itself is busted. Any advice would be greatly appreciated.

Actually turns out a can't post videos but if you put drive dot google dot com before this guy ---->>>. /open?id=1FInsVH2qCofh0-64R3WQG-VL-weYs1wT

you can see what the shifter is doing. It's basically just seizing when trying to travel left and right

Stay safe out there. Best,
Dan

I haven't dealt with STI's much, but it seems that you have some gunk in there. I would disassemble as much as you can, spray grease dissolve through it, add oil to it, reassemble, then watch the park tool video on adjusting and start from square 1.

A couple of thoughts, I suck at fixing derailleur issues:
  1. A few weeks ago I saw this article online about at least two bike shops in Manhattan/Brooklyn that were open - here.
  2. I have twice had a similar problem on my bike. Once it was a plastic cable guide on the bottom of the bottom bracket had broken and the front derailleur cable was binding up there. Replacing the cable guide wasn't too hard once I had the part, while I waited putting some grease on that bracket made shifting easier

    The other time was on my old, old Trek 520 and I brought it to my local low tech but friendly bike shop. He said "Let's soak it in WD40 overnight and then blast it with air - some times gunk just kinda builds up in there and that works. If not, new shifter needed." Lo and behold, it worked - he didn't want to even charge me. so I bought some tubes and other stuff to pay him back.

So, those were my two experiences similar to yours and both had fairly low tech fixes - YMMV...

Thanks so much guys. It's a pretty new bike. This is making me lean toward making something in that shifter went wrong. I'll keep digging. Thanks again!
