Our latest sponsored athlete Cory Foulk tested out our folding SECAs on the streets of Hawaii. He said, "The tires are really light" which at first made him nervous because his events usually feature technical descents with speeds of 60 MPH for long periods. With that said, "These tires ran quiet and straight as an arrow, no vibration whatsoever. Right on!" And the durability? "These SECA's had no flats despite running through a few glass patches."
