Accord to Leonard Zinn... it saves about 125 grams. Someone wrote in and ask that question. He answered on Velonews' Tech Q&A.

Weight is saved on cable as well as the shifter.

That's the idea.
I wonder whether that cross he wears around his neck is titanium.

When you're as skinny as those guys, you don't really have the option to trin weight off your waist. 🙂 These guys get the bike right at the UCI mininum weight.

The ONCE guys had frames so light (through butting) that they would only last one stage. In the Tour Italia a few years back Jalabert's frame had cracked by the time he crossed the finish line.

May be a wee bit of weight savings but I think the other reason is to micro adjust the front der so there is never any rubbing, particularly as these guys cross gear a lot, not worrying about wearing anything out.

Alex am I missing part of your message? It looks like you have everything marked as a quote from another poster by having a > in front of everything including your name. I am assuming, but not sure, that you added the remark "and Joseba Belocki" and then your name but am not sure. What is going on?

and Joseba Belocki
It doesn't surprise me that Beloki uses a DTS for the front. I just didn't notice because he spent so little time in front of the camera. I wasn't paying much attention to the equipment on the bikes but seeing Ulrich reach down to shift was unmistakable.

If they're concerned about micro-adjustments, then an additional reason for downtube shifters is that they aren't on moving handlbars, and don't have long cable housings that need to constantly bend.
Hey, also, no cable in the wind.

Ha. Ha. The context of the comment/discussion is that all professional riders (and 99% amateurs races too) use STI/Ergo levers these days. In fact it has been that way for about 10 years. When did Shimano introduce STI ? About 1991/92? However, to save weight for the mtn stages, many GC contenders will use a down-tube lever for the front derailleur. A couple of posters seemed somewhat surprised by this. I was mearly pointing out that it was nothing new.
Could have something to do with Lance realising Shimano front shifters don't really work.
