Hi..

Recently got a new road bike with Dura Ace Di2 (R9150)
Rear Cassette - 11/30T
Front C.Ring - 50/34T
11 speed chain.

They both is shifting crisp, front and back.
But the sound coming from rear is rather noisy.
Local shop mech did everything again and again for about 3 or 4 time to adjust but still makes no difference to noise.

Is this how it is with R9150 Di2?

This is a mountain bike forum---but nonetheless I run Ultergra DI2 on the road and the cassette is as silent as a mechanical setup---there should not be noise---shop needs to figure it out at those prices---also make sure the chain is going in the proper direct--I mean who knows
