>>1398783less dish for a given amount of gears
with 130 mm hub spacing
>7 speed MTB freewheel>8 speed MTB free hub>9 speed road bikes have a thinner chain and closer cog spacingalso with the majority of freewheels all the gears a permanently joined together into a cluster
so when one cog wears out the rest of the hub is useless
where as most free hubs have interchangeable cogs that form the cassette
so you only have to replace the worn cog
and you can select your own custom ratios much more easily
>al tho in some combinations the Hyperglide indexing teeth will not work>>1398794>the space for the ratchet mechanism and rolling elements are reducedI've never noticed this to be an issue
however i have seen plenty of freewheel hubs that have bent axles or quick release pins
