My first foray into electronic shifting with the LTwoo ER9 electronic groupset. I was able to choose between 10/11/12 speed and opted to go with a lightweight all-steel 12 speed 11-34t cassette (sub 250g). The total cost for the front/rear derailleurs, cables, battery holder, shifters and hydro calipers+hoses was $350 w/tax and shipping. It's crazy how affordable bike parts are going with alternative components.
