Same setup but with flat pedal, and the layering. Your extremities will feel it the most, eg fingers and toes. Get a good pair of gloves, thickness will depend where you’re riding and how cold, also ski mask/balaclava and toe covers. I learned I can have fewer layers since my body will heat up during the ride anyway, and a good windbreaker will keep the freezing wind out. For 30deg below ride, I use bar mitts since I don’t like wearing thick gloves. With the mitt, I can wear my summer gloves under it.
It will take some experience, but later on you’ll have that mental list of what to wear at what temperature.
