.I have been running 40:16 for blasts around flattish areas with a few sharp shortish hills, I was surprised how do-able it was.
Back to 32:16 now for SSUK.. slightly higher inches cos I'm on 650B wheels though.
I'm a skinny fecker though, so the hills aren't a major bother as long as momentum is maintained (alas not always possible in techy climbs)
Riding SS you really have to 'attack' hills (I know that aint a well loved phrase here but it's the best explanation…) If you don't hammer it right away from the bottom of the hill it's only gonna get harder! 😮
