Finally out on my first spin. Need a front derailleur or switch to a 1x. I am seeing a wolf tooth aero ring in my future I think. lol. Still though limited to 36 ring and would only shift down to the 13 and was cruising around 33kph. 32 mm GP5000 AS are actually 34 mm and fit the frame great. Nagging click from the BB I will have to track down.
