I find Trek's sizing very frustrating, amongst other frustrations of the BIG manufacturers. I understand the rationale of reducing the number of sizes that dealers need to keep in inventory but I think the customer is at a loss when their sizing goes from 58 to 63cm.....not to mention no eyelets for fenders, and tire clearances that are ridiculous. Trek and Specialized finally acknowledged that not all riders want to ride with bars 4-6 inches below the level of the seat. I found what I needed in a custom bike for the cost of a Pilot or Roubaix. Rant over.
