    Thanks, My other question is my current Derailleur is a SRAM X5 can i change it for a SRAM X7 ?

    Is it hard to fit a Derailleur ?

    Yes you can.

    No it's not hard. Just takes a bit of fine-tuning to get the indexing right. Plenty of vids on Youtube on how to index.

    I just noticed my derailleur is a sx5 is there a difference between the sx5 and the x5 ?

    And can i change a sx5 for a x5 derailleur.

    Sorry i realise these questions are probably stupid but i don't wont to buy the wrong thing.

    Any Sram numbered dérailleur will work fine.
