What we have here is a used but not abused FSA Gossamer, 3-PC Alloy with CNC 7075/T6 Alloy Chainrings. The is a compact crank that came stock on my F75 felt.
Not really sure, went to the felt website to get the specs for it and all it said is FSA Gossamer, 3-PC Alloy with CNC 7075/T6 Alloy Chainrings. It is nothing great.
