Relating to something I posted in the Touring section but also relevant here ( I hope ) is what would be best for a front derailleur with a combination Veloce QS levers and a compact crank set ( 48/34 ). Would it be better to use an older 8 speed version in either Campagnolo or say something like a Dura Ace 7410? I understand the cages are usually a bit wider and my concern is using a 9 speed Shimano mountain cassette ( 11-34 ) on the rear. The problem of possible chain rub and the ability to adjust with the Campy shifters - I've never used them before.

Just wanted to say that I LOVE what the auto-censor did to the typo in your title.

Something tells me that two of those letters were typed by accident!

I would love to answer this but I have no idea if veloce works as record shifters. If they do you can use any darn FD in the market and it will shift fine as long it can the FD can manage compact. Since a few years ago shimano and campagnolo FD can handle regular and compact cranksets so you should be ok. Now, you mentioned a 8 speed campagnolo FD, probably it will work fine wide wise (crossing chain), the problem in my opinion could be that those FD's does not manage compact. So far were not designed for it, but since some stuff is really cloudy it would not be surprise if it works fine or the chain grains in the 34x15/14 position.

Good luck.

Test it and let is know

veloce QS? not the ultra shift 2009 and newer version?
There's no trim on the older veloce levers.
But it shouldn't be an issue with a double, even with a MTB cassette on the back.
Just try whatever you have sitting around, you'll never know if it will work or not by thinking it through.

I dont think the shifter will see a difference in which fd you use but if your using a 9 speed chain w/ that cassette I would use a fd made for 9 also.

VintageRide

Thank you for the suggestions everyone, I guess I should just try something half decent in perhaps a 9 speed.

Wait for DaveSSS to post the definitive answer. If he doesn't show up soon, PM him.

i recently experimented using a campy 8spd FD with record 10 (39x52). it "worked" but not perfect under load. i swapped it out for a 10spd unit and it works great.

the best FD for your application is going to be a campagnolo compact qs unit. they can be found pretty cheap on e-bay and will have "ct" and "qs" wrote by the model name.

a "normal" campagnolo 10spd qs FD will work, but campagnolo says not as well (i personally have not tried it)

a non "qs" 10spd derailleur should also work but will require more shifter travel and wont be as good as the "ct" either

Still a bit overwhelmed with the choices out there. I saw an inexpensive Veloce 9 speed changer but it says it is not for compact cranks. I know many use standard front changers with them anyway, and with the 34/48, I can't see any issues. Thank you for the links by the way, my problem is I need a 28.6 clamp on version, and there does not seem to be too many choices with Campagnolo. I see they have braze on clamp adapters, but 32mm seems to be the smallest.

i would use the first one i posted.

to the the best of my knowledge, the only difference between a campagnolo 9spd FD and 10spd FD is the plastic "wear pad" on the outside of the cage. if you have any rubbing issues this could be removed.

As I remember, this is because this model was designed (claimed) to better match the curvature of the smaller larger chainwheel (53t versus 50t).

thirdgenbird

correct. the "ct" FD has a smaller tooth max for the outer ring. i cant recall what it is, but it's smaller than 53t.

They did away with 28.6 several years ago, but most LBS should be able to get you an appropriate shim to use with a 32.

thirdgenbird

i would recommend using a braze on adaptor.

you can also get an older 28.6mm clamp from an 8spd derailleur and switch it to a 9spd or 10spd derailleur.

I decided on a Centaur braze on 10 speed QS changer which looked a little better than the Xenon and Mirage equivalents, as the prices were close enough.A Problem Solvers 28.6 adapter clamp in silver finish and a nice front pulley from Superfly Cycles. I almost decided not to spend the 50.00 odd dollars ( including shipping ) but what the heck, it's a nice sealed bearing piece. They probably will not include a bolt .At least now I will be set up for a bottom pull configuration and hopefully I will be able to get this project together before Spring. Thanks again everybody!

thirdgenbird

the problem solvers clamp suits campagnolo derailleurs very nicely. great choice.

VintageRide

I almost purchased the Xenon ct version in your first link but went for the slightly upscale Centaur, the description mentioned that it is compact compatible, but then I imagine one could get any number of other standard front changers to work also. I did realize the inner plate on that Xenon would probably facilitate somewhat better shifting, just hope I made the right choice. When the pulley costs more than the derailleur with shipping it seemed somewhat wasteful, but nobody else that I could see really bothered, they were all the friction type. Performance wise I am sure there is no tangible difference, but I can see it for the cyclo cross crowd when they get a lot of mud and debris around the pulley, a sealed design makes sense. Just a bit overkill for a touring bike with fenders.
