>>1698518with smaller chain rings the gaps between discrete gear ratios becomes larger
then compounted by by the cassete only haveing 8 speeds
that Btwin Riverside 120 has an .eg 36 teeth chain ring
and CS-H081 11-13-15-18-21-24-28-34
old bso has chain rings of
48-38-28
and free hub of
14-16-18-20-22-24-28
so the range is the same but the gaps between discrete ratios is different
(iirc there are 14 discrete ratios in a 21 speed system unless you half step the chain rings)
>Does anyone have experience with a drivetrain like thisI found that 1x drive trains have to give up either low or high gears depending on what size of chain ring is in use
MTB goes for low gear ratios and tiny chain ring
Lesure bikes look have basicly the same range as old bso
Road bikes have to give up on low gears or resort to 10 or 8 tooth sprokets
>Road riding / commuting?sure thats mostly on flat ground
24 gear inches allows you to climb hills at 5 kph / walking pace if you can maintain 30 rpm
55 gear inches is perfect for 30 kph on flat ground
80 gear inches is as much as i've ever found use for 40 kph in this gear is no problem
