Lightweight front derailleurs

[Mod-Master]

Does anyone know a list of the lightest front derailleurs? Disraeli gears do not have a collection of front mechs and just wondering what are the lightest for a weight weenie build.

Cheers

Seen that xc pro proves to be lightest…

And why do you think I chose one for my OCLV...?

Your Suntour XC front mech (OCLV) has a weight of 118 grams. What is the clamp size? Supposedly the Campy Record OR mtb front mech is lighter than the Suntour and Shimano units clamp size for clamp size. I am particularly interested in that one (in 34.9 mm) if anyone has a spare they can weigh. Maybe Proshift is lighter than all three?

Mine is a 34.9.

Was just looking for you.
Grabbed the code from the 1993 catalogue FD-03FOR
(that's the large band size)

122g from a decent weigh in https://weightweenies.starbike.com/forum/viewtopic.php?t=167613
But no idea if that has been reduced with Alu bolts as one might expect for a weenie build there.

Mine still has steel bolts too @118g

If period isn't a bother then the braze on Dura Ace fd7900 is the lightest standard mech. It is 66-67grams. I think the band-on version is 75ish.
I use one with one of those exotic carbon braze on adapters and a Speen umlenker as it is a down pull mech on a top pull frame. The adapter and Speen thing only add about 10grams.
Changes very well with bar ends and I haven't had any problems in months of use.
