The Arrivee was made only two years 2003, 2004. It is straight gauge with standard 1 1/8 head tube. The Tete De Course is double butt gauge with shaped tubing on the top tube and down tube, also comes with intergrated headtube. Tete De Course is about 1/2 lighter in the fame.
I road a Tete De Course may years ago and loved it. I picked up the Arrivee because they stopped making full Ti but that new mix or carbon and Ti. I still think that Lemond should go back to making at least one bike in the line full Ti. THe carbon mix rides ok. But nothing rides like a full Ti bike. And you can have a Ti bike for 10 years and it still looks new.
The Arivee rides really well. If no one has ever ridden a Ti bike its hard to explain. But more like a steel bike with less vibration. Silky smooth. I think this is my 5 lemond and my favorite so far.
The bike is fare from stock. Its a 2004. Full 10 spd Dura Ace, Thomson Masterpeice setback seatpost, Thomson X-2 stem, Chris King headset, Chris King 32 hubs, DT Revolution spokes, Mavic CXP-33 rims, Easton EC90 SL straight fork, Easton EC90 carbon bars, Flite carbo seat, speedplay x-2s.
I think the only thing left stock is the bar tape and frame.
I am in the process of trying to find a Tete De Course in a 55. Still want one.
