Important:
* Use original FSA bolts and spacers for Gossamer cranks. Nothing else is required for mounting these rings.
* For SL-K, use original FSA bolt covers and bolts that fit perfectly. Nothing else is needed to mount these rings.
* For K-Force - additionally purchase absoluteBLACK bolt covers. This is essential, as you cannot mount these chainrings on K-Force otherwise.
* Ramps on large rings are specifically configured for combinations: 50/34, 52/36, 52/38, 53/39T.
* If you want to use a different configuration, it will also work, but shifting will be slower and may require more adjustments to the front derailleur to be acceptable. Also, keep in mind that the front derailleur can only accept a maximum difference of 16T between two chainrings - this is how Shimano and SRAM designed them.
