Post by: oldschoolace on January 04, 2014, 08:47 PM

Ok so lets say i have just applied to Guiness to achieve a land speed record on a bmx  ;)

Assuming i went with the principle of this guy with a big fookoff chainring:

Keeping it oldschool whats the largest chainring you could run on an unaltered bmx frame, and any idea which frame would give the most clearance? :D

Would 48-9 not be enough for starters, or are we talking laughably huge gearing here?

Watch the 1st episode of speed with Guy Martin,  3 cogs is the way forward for monster gearing. :daumenhoch:
