I just wanted to run a few parts by you that I am not really familiar with and see what you know about them. They come stock on a bike that I am currently looking at.
1. Ambrosio Excellence Wheels
2. Orbit x-1 Headset
3. Propulsion Kevlar Tires
4. Gigantix? - Seatpost
These are standard on the Marinoni Piuma that I am looking at. Upgrades are available but I want to know if I need to bother upgrading these parts. I am mostly riding for fitness (serious fitness) and participate in a few triathlons and road races.
