SRAM Force Crankset 54-39T 11-Speed ( 17.5 cm) - Resale price?

[NOFX]

Hi Chaps,

 

Apologies, i know this is mundane but i need to sell my 200km old SRAM Force Crankset 54-39T 11-Speed (17.5 cm) due to a knee injury and a need for slighter gearing.

 

Do you perhaps know what the asking price on this crankset would be if advertised on BikeHub and Facebook would be?

 

I personally would not have a clue , but i know the 50-34t crankset retails in bike shops for R 6000 as i have just purchased one.

 

Any idea's of resale price?
