Came up 80% single 20% double for me.
I actually swapped for tris year to 1 x 10. Haven’t missed the other chainring at all. I tend to mostly ride trail centres – albeit some with large hills. CwmCarn is a fairly big uphill for me.
I made sure when I swapped that I still retained the lowest gear ratio – so I’ve got a 32f / 42 rear for this with a Sunrace cassette.
I rarely used the large chainring on the double except on bumpy downhills to make the chain tighter so less likely to lose it. If I’m going fast enough to spin out 32/11 then in the terrain I ride hen I probably don’t need to be pedalling any faster.
I think I’d feel differently if I rode a lot of trails with fast road sections / long fast fire road downhills. But I don’t.
