Does an expensive bike improve an amateur cyclists performance?
That's what Matt Haughey wanted to know. So he did some research to answer the question, "Does a $5,000 bike improve an amateur cyclist’s performance," by renting a Cervelo R3 for $300 a week. He shows the percentage of increase in speed/time over several distances, comparing against speed/time on his $1700 aluminum bike. On a 35 mile route, he shaved off 21 minutes, 13 seconds, a 15% difference over his performance on the aluminum bike.
