Can anyone advise what’s going on with my drivechain please? For the last couple of months my shifting has been a bit suspect, especially in the lowest gear where it feels like it’s skips and can’t seem to catch properly to the point where I just don’t use it. Over the last few days it’s got worse and is happening when cycling through all the gears which feels dangerous in traffic.

I thought it might be jockey wheel but on inspection today it looks like it might be something else! The bike is only circa 6 months old. Any advice would be much appreciated on what I can do to fix it.

P.S. This is a P line 4 speed cassette.

Thank you!

  1. Looks like on the video your deraileur set right between gears and the chain getting pulled to bigger sprocket at it should. 
    I think you need just a bit more cable tention. Set it on biggest sprocket at your shifter and adjust tention so chain should be keeping on this sprocket not trying to escape.
