is there any difference in speed from the m03 to an m05?
has the m05 got the same gearbox as the m03? & can you only use same 3 pinions 16t,18t and 20t?

as i have a very fast m03 club champion for last 2 yrs and don't want to go a buy new m05 if no speed diff as i could be wasting money

can anyone help pls?
