note
>>1890792I also have an old 3x7 bike
for hills 28-28 is pretty bad desu as its better to maintain 15 kp/h, id really like to have at least 22-34 so that 5kp/h can be maintained
taking off from intersections I like to slam shift between 38-21 and 28-38 (had to shorten my chain a few links for this to work)
as for down hill ive hit 70 kp/h using only 48x16 and 40 kp/h sustained is no problem, so I'm sure that a chain ring between 42 and 46 teeth is better for my use
>3x8half step with a granny ring might be neat for that
