SRAM XG-1275 GX Eagle 12-Speed Cassette
These items are like hens teeth, thank you for assisting, I couldn't imaging 2 months without my bike:)
Getting one of these at a reasonable price is rare at the moment. Pleased to say bought one from Sprocketts when all others out of stock. See they have all been snapped up super quick now.
Really great service, arrived on time and was exactly as described 10/10
