I would love a cyclocross SS, like a Day One or Pompino, for commuting this summer on fairly flat part off road, part road route. but can’t find any second handers at the moment at an affordable price, so I’m looking at upping the ratio from 32:16 on my Genesis IO.
Can’t go smaller than 16 on the rear as its a SS hub with freewheel, and smaller freewheels have a different thread. So instead looking at replacing the 32T chainring, putting on the outside of the crank mounts (for clearance with the frame), and hoping this won’t put the chainline off too much. So what ring size should I go for? All I know is 32:16 is way too spinny on the flats. Day one comes with a 42T, Pompino a 49T, so not much help for me there, plus they’re 700c so will have a slightly different ratio.
Ta muchly.
