I converted my 2014 Sirrus to 1 x 12/36 a couple of weeks ago and the Shimano cranks that i ordered came with 36t chainring, i have a 40t chainring waiting to be swapped but have been too lazy to do so. As my username suggests, i ride slowly being in my early 60's and not in a hurry, so a 36t chainring works fine for me as well.
