Took my SL7 out for a gran fondo over the weekend. Currently running my Specialized Turbo 26" tires at 80 psi. Felt a lot of road vibration from shitty roads, thinking about moving to 28" Spez Turbo Cottons / Vittoria Corsa G2.0 and run them at 65 psi.
Now a friend has 28" tires and says he still feels quite a lot of road vibration, but he also has 10kg on me. So not sure if the higher pressure would effect this.
Would moving to 28" @ 65 psi allow me to notice a difference in removing some of that road vibration…as the Roval CL wheels are designed around a 26" I’m reluctant to go to 28"
