I am selling my race wheelset because I bought a new bike. I had the wheels converted to tubeless and rode them very well, even though the rims were not originally designed for it. 25mm Continental 5000 TL tires are mounted. The tubeless sealant needs to be changed. The rear wheel is sold without a cassette; I always rode it with Shimano 11-speed Ultegra. Sold with quick release skewers and spare spokes.
