Carbon wheels - Giant SLR2 50mm

Mint condition Giant SLR2 50mm carbon wheels with Giant Courseo racing tires 700x 28c and Shimano 105 12 speed cassette and Shimano disc brakes. Only used twice as upgraded bike which came with better wheels and was keeping them as a spare set. To buy brand new they are €475 each and the cassette would be €110 minimum, I’ll take €500 for both and even give a free unopened one litre bottle of muc-off tubeless sealant. I know I’m losing money here but I need to declutter before my wife makes me keep my bikes outside :-)
