Hi I have a 2017 S40 that has a sram drive train 2x10 drive chain. I want to convert it to a 1x11 or 1x12 and get rid of the front shifter. Has anyone done this? If so could you tell me what would work on the S40 and where I can get it?
Thanks
 
I use a cheap square taper short (150mm) crankset with a very cheap ali express narrow/wide chainring. Shimano GRX 11spd rear mech.
Worth thinking about short cranks if your having to change them. There are threads on here about them.

The source UK BMX shop. Heres the link but you should find something similar if your in US.
Also, you have to have the correct freehub but Sram do cassettes down to 10 tooth which can be handy with a 1X setup if your a faster rider. I get away with a 42 tooth front ring and 42-11 tooth cassette but am not worried about speed and I've always been a spinner. I can pedal at 50km/h pretty comfortably. I can also get up shorter 15% or so hills no problem.
Hope thats some help.
