I have been biking for 20 years, and do have big legs. On 2/22/2008, the day after my bike ride to Oakland, my right thigh was a near-record 73.8 cm (29 1/16 in). On 7/7/2008, 5 days after my bike ride to Hollister, it was 71.6 cm (28 3/16 in). On 5/24/1997, the day of my bike ride to Half Moon Bay, it was 71.2 cm (28 1/32 in). On 5/7/1998, it was a record 75.8 cm (29 27/32 in). For most of the 1990’s, I used high gears. My favorite bike during this period had a 108-inch gear (52×13, 27-inch wheels). about 5 months before the bike became completely disabled, both derailleur cables broke, making the highest gear the only one available. I continued to ride it right up to the time it was unusable.
