there isnt I've used them both. I could be wrong but i THINK piston shape or something along those lines is different in the master cylinder? Again I could be talking nonsense haha.
Well the quality of the levers themselves are completely different, considering I snapped my friends mt5 blade that was only a few months old.... Peace of mind for me I went for these macaskill ones. Like I say, I don't exactly buy brakes often and got an insane deal on them Other than that I completely agree where everybody is coming from.
