  • I am struggling to get my rear derailleur to shift to both the smallest cog and the largest

    If I lower the cable tension then I can get it into the smallest cog, however, then there isnt enough tension to get it into the largest.

    The moment I increase the tension the derailleur moves left slightly and its then impossible to get the chain onto the smallest cog but it will then at least go into the biggest cog

    Any ideas??

  • Hi are you sure your shifters are as should be, if yes, limit screws may need a tweek

  • When you adjust it so you can get the smallest cog is the shifting better over the 3 or 4 cogs at that end of the block than the 3 or 4 at the other end?

    Vice versa, if you adjust it to get the biggest is the shifting better at that end?

    If so, the hanger is bent.
