This is a remix of the original 2008 video, with a 5X speed-up of the middle segment of both climbs, set to duty free electronic music.
Original 2008 Description: Cycling Instructor/Aerospace Engineer, Dan Gutierrez uses a special bike he created to climb straight up Fargo Street; the toughest hill in North America with a 32% grade for over 1/10 mile in length. This video was shot on the day of the LA Wheelmen Fargo St. Hill Climb on March 16th, 2008. Brian DeSousa did the tripod and hand-held video camera work, and Dan shot the helmet camera video. This video demonstrates that the concept of adding a second crank to a single bike - in this case a cyclocross frame with long chainstays - and modifying the rider position, allows stable operation with ultra-low gears at very low speeds on a very steep hill. Previously, it was though that one needed a tandem with a long wheelbase to both allow gear reduction and low speed stability on this type of climb. The reason for doing this is to climb the hill at a much lower bicycle weight (20 lbs) compared to using a tandem bicycle (40 lbs) with similar two-shaft/crank gearing, so I'm lugging half the bicycle weight up this tough hill compared to using a tandem. Since many have asked, the gearing used was as follows: Left side drive 20T lower crank, 45T upper crank. Right side drive 20T (same shaft as the 45T on the left), rear cassette 11-32 8sp The two gears used in the video were on the 32T and then 28T cogs, 7.5 and 8.6 gear inches respectively.
