I am offering this masterpiece of mechanical engineering for sale. XX1 gold derailleur and shifter, Sram GX cranks, Sram X01 11-50T cassette, Sram XX1 rainbow chain, chainrings: steel 32T or XX1 SL 34T (costs 100€+). The cassette has a maximum of 1500km, the chainrings have a maximum of 500km and are like new, the chain has under 500km and is like new. Theoretically, it is possible to sell the parts separately, but you will have to offer an interesting amount.
