One thing to note about the Domane is its ability to take on a 40 tire which is awesome for gravel. I bought Aeoulos XXX 4 TL for road riding with 28 TL Conti 5000s and have a set of the Pro 3V TL on order for gravel that I will equip with 40 tires. While the bike is speced for 38c, I tried a neighbors 40 and it fit with plenty of clearance in my opinion. Thankfully, only gravel farm roads as I don't want to ding this beauty up.
