Just watched a video of the '97 Tour of Flanders and noticed that Jalabert had a Shimano downtube shifter for his front derailleur on his carbon fibre Look. He was riding for ONCE at this time. I thought this was just a Lance TDF thing, but I guess it goes back some years.

Also, I read in Cycle Sport that Campy has just designed a complete drivetrain with an intergrated downtube shifter for the front derailleur.
It's as old as STI,TJeanloz

The practice of using a downtube shifter on the front is as old as STI - once somebody realized that the STI unit weighed more than the downtube shifter + brake lever.

Andy Hampsten was one of the first to be seen with this combination on the climbs in the Giro and the TdF in the early '90's.

of JaJa riding LOOK's with 1 downtube shifter. I thought it was a Lance thing also.

I actually like a downtube shifter for the front, anyway. It's much more positive to me. Around here, you tend to either go up for a while or down for a while, so you aren't going back and forth on the rings all the time, anyway.

Integrated does work much better for the back, though, except on time trial bikes.

I have used both Campy and Shimano. They work equally well.

I tried a dt lever for the rear, but it would not hold against the rd spring. Kept pulling out of gear, especially in the big cog.

What brand and model do you use? I don't see that Campy currently makes a downtube shifter.
Campy no longerDougSloan

This is at Branford's site:

"Downtube Shifters

Campagnolo no longer produces any downtube shifters.

If they change their mind we will let you know and post them here."

Shimano still makes them:

Shimano levers on a Campy bike! We better keep this one quiet. I won't say a word.
not me; are you kidding?DougSloan

I actually snagged a Campy set before they stopped making them. I had a Shimano lever on the EV2 when it had Dura Ace.

For the front, it doesn't make a bit of a difference. There's no indexing. The Campy lever seemed to be a little more durable looking, where it has some brass parts compared to the Shimano plastic (but probably heavier, too).

If you put a Shimano lever on, I doubt anyone would ever know. The logos are really tiny on these things.

What is an "integrated" down tube shifter? nmbsdc
Jan 20, 2003 10:38 AM
probably means "indexed" nmDougSloan
Jan 20, 2003 10:43 AM
isn't the point (besides weight) to be non-indexed?Spunout

Besides, this is a Shimano problem with the left shifter. I can micro-adjust the front just fine with Ergos.

For the rear, they allow indexed or friction modes. The fronts are not indexed at all. No need -- you just slam it one way or the other.

FYI - Cycle Sport reports Campy's new downtube shifter in their Sept., 2002 issue, p. 98 at the "BIKE MONTH" section.
