Hi Guys,

I can't seem to find any information regarding the correct length of inner chainring bolts required for Grafton Joystix cranks. The bolts I have which are 15 mm were sold to me as being correct for Joystix but seem to be too long. I didn't think that spacers were required for Joystix but maybe (very short ones) are.

Does anyone have experience running these cranks? Any advice as to what are the correct length of bolts and what spacers I may or may not need would be much appreciated before I have to go and buy some shorter inner chainring bolts.

Thanks very much in advance.

Hi,
My FRO is equipped with a set of Joystix.
I'll try to see if I can unscrew one of the bolts (and spacer?) that holds the inner chainring this weekend in order to get you dimensions. Hopefully this can be done without having to remove the cranks..
Not sure whether these are the correct ones, but at least they work :)

Just checked: no spacers indeed, bolts just over 8 mm (but not as long as 9 mm..).
Hope this helps!
