World time trial champion Tony Martin drew a host of ohhs and ahhs when he chose to run a massive 58-tooth chainring in the one and only TT at this year's Tour de France. That big ring paid serious dividends, though, as Martin crushed an over-matched field, winning the 54km stage by 1 minute and 49 seconds. The German's average speed for the hour-long effort was just a shade over 30mph.
Now imagine if you could get Martin on-board the stealth bomber of a bike featured in this video, which describes the tale of a small U.K.-based frame builder and his need for speed. Using a massive 104-tooth chainring paired with an 11-tooth rear cog, he wanted to see just how fast he could pedal a bike. Have a look at this inspiring film from SpindleProductions.
