I’ve got a mixture on various bikes. Was just wandering where it will stop.
I’ve got 2×11 on the road bike (great range of gears)
1×11 on the trail bike (lacks a bit of a really easy skinny gear for long technical climbs)
2×9 on a hardtail for mucking about on in flats.
2×10 on my xc race type hardtail (love this gear set up but it does sometimes drop a chain).
