Long story short. Had a road bike years ago, went to do death ride, never made it there. I now want to do death ride again next year, but have no road bike. Have pretty close to a road bike a Specialized Diverge aluminum. Heavy with aluminum, cheap wheelset, and disc brakes. Would be tough to scrap up money but being that i am going to go back to repeats on Diablo this next year and the ride itself. Would you spend the money on a new bike (N+1) or would you put a thinner tire on it. Thinking i should get a new bike to ensure success, what do you think?
