Not ridden yet but looks solid and easy to setup through the app. Shifters and brakes look pretty neat. Hoping it performs as good as it feels. Love how you can fine tune each gear for slick shifting

Funktion very smooth.

Comes in 2 separate boxes so you don't get scared. It looks good I have to install it yet. But it looks very robust. It weighs between force and red.
C
Exactly as described! I can’t wait to get it mounted to the bike and get riding. Came well packed and was very quick to arrive.
