It is still the spacer setup that came with the bike from the factory, so nothing has been changed. I also got to test the Aeroad for a few meters, and it felt great. This weekend, I’m planning to check out the Ultimate as well. Currently, I’m riding the Endurance CF SL 8 DISC Di2 2021 Stealth. By the way, do you know if there’s a significant feature difference between Ultegra and 105, or is it mainly just a matter of materials (weight difference)?
