安価でも必要十分です。運良く、調整不要でビシっとギアチェンジが決まります。

I do a lot of cycling, build and service my family's bikes, and have used many types of gear changers. This is by far the worst I've ever used. It's really hurting my thumb when I change onto the big ring. The rear gear changer is fine, but I recommend not buying this one for your front shifter.

シンプルで操作しやすいです。

The review is for a two speed left front shifter. Came with inner but without outer cables. Couldn't find a way to fit it to my handlebar without handle touching something, either the back of the brake lever clamp or handlebar grip, a really huge handle (lever). Perhaps the reason that I couldn't fit it properly is that my handlebar is slightly curved, not straight one. Eventually I had to reduce the size of the plastic part of the shifter handle by cutting it, and thus removing almost half of it. I did that with a small metal cutting saw and a couple of metal files (Straight and one round file). Then it fitted fine. The pull is quite long, meaning going from 1 to 2 isn't exactly brief, which can be attributed to the long handle I presume, while the return is swift, where with one click it is back in the position 1. The amount of strength required to push it with your thumb from 1 to 2 is medium, which is fine for me, but for someone with a weaker thumb it could be perhaps somewhat demanding. Shifting action appears to be precise. All in all it does the job fine, but why they make them so chunky is beyond me.

　街乗り用MTBをフロント2速化する際に購入。　操作は親指で前に押し込みシフトアップ。軽く2回押すとシフトダウン。また人差し指で手前に押しても元のギアに戻る。　これまで2本レバーのモデルに乗っていた人でも違和感なく使えると思います。私は使いやすく感じました。
