Hi guys

Bought a new rear mech received it today (after mine destroyed itself) set the limits eveything was fine until i shifted into the smallest cogs front & rear, the chain just seems to be very slack and jumps (i m not actually suprised its so slack). Thing is i cant work out how to stop it doing this any tips ? my chain & cassette are not worn & the chain is the the correct lenght when in the largest gears.

    mech cage too short?

    but it is not a ratio you will ever use.

    Have a read of the FAQ on how to use gears, it explains these ratios and why not to use them.

    and if you have 3 rings and a wide range cassette then the mech cage is too short.

    see the FAQs for that as well.

  • had a read, looks as though i should be using a long cage at the very least a mdeium. Lucky i bought a used item. Thanks for the help.
