I've been preferring tubulars ever since I started riding them four or five years ago. Today's ride, first in a while, was on this PF10. Originally a PFN10, so I was told, the N indicating it had clincher tires. I reverted it to tubulars, hence it is now a PF10. Love it, love the tires. My go-to tire is Veloflex Criterium, 23mm.
