Purchased these in February 2018 from Competitivecyclist.com. They are a fast rolling wheel. Clinchers with a 55mm deep rim. I have dark grey rim stickers that came with them as well if you don’t like the white. You will have to run 60mm presta tubes or get a extender. They aren’t too bad in heavy winds either. You can have the Specialized Turbo pro tires that are mounted (they still have good tread). I’m going full disc on my bikes so no use for these.
It’s a shimano cassette. 11 speed. Put a 1.85mm spacer on it and you can run 10 speed. The spacers cost $5.99 on Amain Cycling online.
