I am really confused. I would like to replace my 7-speed shimano MF TZ21 14-28t gearing with a 11-28t gearing. However, I am not sure whether I have a freeewheel or a cassette. Mine is identical to this one:
Will the shimano HG-30 11-28t or HG-70 11-28t fit my setup?
Hi clksoft, iread you have changed your chainring from 46 to 60t, from your folding bike, but what happens with your distance of foot pedal to the ground?
Pedal-to-ground clearance is determined by crankarm length, not chainring tooth count. With the same crank/crank length, going to a bigger (more teeth) chainring doesn't change the pedal-to-ground-clearance.
(well, maybe a tiny bit when cornering IF a replacement crank has the same length but a bigger Q-factor - pedals wider apart.)
