Have bought myself a BMC teamelite with DI2 XT M8000.
With the bike came a crankset with 36/26 chainring.
This is to small for me because this MTB is for the rainy days on the road and some beach races.
In the first couple of rides i almost rode the whole time on the 10th or 11 teeth.
Now I know that there is a 38/28 option with Shimano but I would prefer a 40 or 42 teeth chainring.
Not necessary that it is double a single is also good for me.
I think it's obvious that I don't need a TRIPLE!

Someone nows a solution?

I heard from my dealer that rotor can provide something like CX narrow wide chainring on a MTB spider. Don't know if that's a good solution

biggest I've seen that is M8000 single/NW is 36t

You may be better off changing the crank to a 4 or 5-bolt 110mm BCD, and then using a ring designed for CXing, like Rotor, or Superstar, or Hope, or Blackspire.

I run a 42t on my cx bike, and imagine if you're not riding too much in the mountains then you should be fine with that.
