We’ll that killed the thread :/
A couple of rides in and I’m loving 1×11, my concerns about the steeper climbs (where I’ve been locked into the granny ring and the bigger end of the cassette) have been dispatched with ease, without resorting to the supersize 42 AT&T he back.
I’m still in the ‘new bike’ honeymoon period obviously but so far so good.
Big thanks to Nevis Cycles for sorting the bike and dealing with all my questions :)
