2013 Bikes

How about 1x11?

I'm still on 9spd until I run out of spares.

Was reading about this this morning. Thats a fecking 10-42 tooth cassette!
My fat bike will get a 10 speed Sram with 31t chainring, and a 11-36 cassette.
I want 10-42t 11 speed cassette.

It has vertical dropouts and an eccentric bb according to that article. So it's designed to be versatile like you say.

I cant really see folk swapping all the bits I mentioned for weekend rides.
But its an amazing entry into the 29er world.
Definitly worthy of upgrading over time.
