Interested in the advantages of 1x11 speed over 2x10.
I'll be the first to say I like the clean looks. For new frames, I can see that 1x11 would allow some suspension designs that wouldn't be possible with a front mech. I'm not aware yet of any frames taking advantage of this though.
Fewer dislodged chains when changing into the granny ring and weight are the only things besides these that I can come up with.
I don't really have problems with maintenance on a front mech. Cables and the mech itself last forever.
Anything I'm missing? Besides being more enduro.
