We would need to see your bike in particular to advise directly.

Bolts and spacers

By John

I was wondering what bolts I need to hold this together with a Thorn 104mm BCD 4 Arm Reversible Single Chainring 3/32 Inch - Black - 36T and a 104 spider? Do I need any spacers?

SJS Customer Service:

Hi there,

As you would be using this like it is an outer chainring, you don't need any special bolts or spacers, just bolts for a double chainset.

Thanks

Can I Fit This Onto My Shimano Xt 10 Spd 24/38T Chainset

By Sam

I don't want to replace my outer ring with this I want to fit this in addition?

Also will i need spacers and longer bolts?

SJS Customer Service:

Hi,

If it is the dedicated Shimano XT double then it will not fit properly as the very outer position is not designed to take any rings and mounting it inside the chainring tabs will cause it to push the chainring too far in. If it is originally one of the triple ring chainsets then it will fit with only longer bolts required.

Thanks.
