I ride a 2004 Lemond - stock. I weigh 220 and my brother is 250. We train in the San Francisco Bay Area. I good training ride for us is 100 miles north of SF.
In 2005 I did the Solvang Double, the Davis Double, the Marin Double (DNS - mechanical) and the Knoxville Double.
Now I commute 40 miles a day - 3 days a week plus a 3 hour hill climb ride on the weekends.
