Hi all,
This may be a stupid question but I want to change my crankset set up from triple to double?, in order to fit a bash ring, can I just remove the outer ring and fit the bash guard, then do I then just have to adjust the front derallier? I wouldn't need to adjust the length of chain would I????

    Remove outer ring, replace with bash guard, adjust limit screw to prevent shifting past middle ring.

    Your chain will be too long, as it is sized for the largest chain ring. You could leave it if you want but it's best to have it sized appropriately. You'll also probably be running a long cage mech where you only need mid cage. Far from essential to replace that though

    In terms of fitting a bash, the plastic ones are much thicker and need longer chainring bolts, you ideally want an aluminium one which has a mounting section the same thickness as a chainring.

    Oh, and size the bash guard based on the middle chain ring that is fitted. So if you are thinking of going slightly larger in the future bear that in mind.
