3 Sprocket mod – how to get 12 speed gear range on your 6 speed wheelset

I don't think I've seen anyone document the process so I thought I'd film it when I got the chance to do this mod for a friend's bike.

I think for most people the hub replacement from Brommieplus makes more sense since it's easier than modifying the circlip but if you want to save more money then this option is pretty straight forward too.
