At the moment the zee shifter/derailleur setup is very reasonably priced considering the quality the shifter + derailleur can be had for about $75 us. I am running a 1x10 system with 11-32t cassette, 56t chainring, and 406 wheels 1.95" tires 35-100 gear inches.



and with 16" wheels you would want as much clearance as you could get I would think.
