I used to ride and race on Turbo Cottons and really liked the performance, except that they don’t last nearly as along as a GP4K / 5K. I also had two delaminate where the tan sidewall separated from the main casing. The tires didn’t go flat but I replaced them as soon as I noticed the issue.
I switched to GP 4Ks and now the 5Ks. Great tires from every perspective - long lasting, aero, and good rolling resistance. Can’t go wrong with them.
