hwheel72 What do we know about Veloflex Roubaix sidewalls? Some of the EroicaCA gravel is sharper than cobblestones. I'm a Sprinter Gatorskin for gravel fan and used them (25s) the last 3 years but I have been tempted to get some fancy and nicer riding tubulars that will be fun to ride on during the rest of Spring and early Summer -- if they survive the Central Coast Gravel.
