I got some bad news from a bike shop tech. I need to replace the Chain, casette, and both chain rings. My Cannodale Super six EVO Hi Mod is tired, very tired. This is going to be expensive. I am going to hit my 401k for it. I will upgrade to super high-quality wheels but I will keep the clincher brakes. This leaves me no choice but to race the bike next year. I hope I can compete in a 75 and up division but I will probably have to go with the fifties. Carry on and may all your turns be right turns.
