And btw, I just got the new Veloflex Corse tires (just relreased recently). It's nice. Feels almost as soft as their older ones (which you may have?). The newer ones use a slightly thicker bead (for safety with carbon rims), so it's a tad thicker and heavier. But still more supple compared to the GP5k, a lot more.
Thanks! I am sticking to 24mm Turbo Cottons on my CLX64s, but was thinking of putting GP5ks on the CL50s, which are my daily riding wheels. They are 30mm OD, so i am hoping the 28mms will fit them well enough.
That said, they arent my favorite tires either, and you now have my interest with this talk of the new Corsas. Are these the new tubeless versions that were announced recently? I gave my last pair of Corsas to my wife a couple of months ago - I have a pair of Wolfpack tires that are next in queue, but if the new tubeless Corsas have the same ride feel as the older ones, may jump on a pair as well.
