This is a bombproof Fulcrum wheelset. Fulcrum is the sister company of Campagnolo and known for their high quality, reasonably priced wheels. There is less than 100 miles on these wheels as I used them while waiting for another wheelset to come in. The are true, roll great, and are taped and ready to go tubeless or with tubes. Valves included. 12 x 142 rear and 12 x 100 front so they are compatible with modern road bikes and gravel bikes. Please reach out with any questions.
