Campagnolo Record 10sp front derailleur...

[Ruimteaapje]

These front derailleurs from before the switch to the model which could handle both standard and compact cranksets. Who knows from experience what diffence in chain ring size they can handle - only the 14t difference they were designed for or can they handle a bigger difference?

They will work fine with standard, compact and mid compact. The cage dimensions didn't really change all that much in 2008, when they stopped making 'CT' front ders and just 'upgraded' the 14t max to 16t.

With ERGO levers..I just put a C Record crank with tripleizer using a SR(like from 1976 or so) and it works great...ERGO makes for lotsa flexibility. 48/40/34 TA chainrings.

Thanks! So 52/36 would work fine? I was about to order a set of 52/36 Extralite rings and try to avoid an expensive mistake :D

Yes it will, no problem.

I'm using one with a 52/34. Works fine.

I’m using one with a 50/36...works fine.

[Ruimteaapje]

Thanks all!

I've often thought of trying 52/34. How does this setup work for you?

Basically, as expected. Which means: It is normal that the bigger the chainring differential, the slower the shifting between chainring, so just as 52/36 (16T diff.) is a little slower than 53/39 (14T diff.), 52/34 (18T diff.) is a little bit slower than 52/36. Also, a bigger chainring differential can mean a bigger chain chance of dropping the chain, but with an anti-chain drop device installed (I'm using a K-Edge), chain drops can be eliminated.

The large chainring differential can also means a bigger change in cadence when shifting between chainrings. But I'm already used to doing front/rear simultaneous shifts when shifting between chainrings, which minimizes changes in cadence.

Yes. Campy is fantastic for facilitating this... well, at least at their higher levels.

Sigh... oh, for the good old days ;) ... I have a set of lowly Mirage ergos from ~ 2005 that drop multiple cogs just like their pricier cousins.

Its for such reasons that all my bikes are still basically 2007 10sp Record and Chorus.

I'm a fan of the older 10 speed, even over 11. If you like the 10, you will love the new 12. It has that precision and snap that Campy is noted for. I have two 11 speed mini groups and a full 10 speed group not on a bike and I will keep the 10 speed any day.

I've found my Record Titanium FD to be pretty miserable going up. I'm riding 50/34 Record CT cranks and it often takes a couple of pushes of the lever, or more of a press and hold, to upshift. I've messed with it a bunch and that's about the best I can get. I'm pretty sure the cages, titanium and carbon are flexing....

That sounds more like a derailleur adjustment issue. I've used Chorus (aluminum) and Record (aluminum and carbon fiber) 10spd derailleurs, and not experienced what you are describing. There are ways to adjust the derailleur to shift more aggressively to the big ring.

Went thru the find a front mech with my Campy 10s setup recently.

48/36/24 triple, with a Campy 11s Athena front mech,
the derailer cage would hit the middle ring, when the mech
was set a the correct height, had to raise the mech, which made
for very fiddly setup, a B- functioning, would toss chains to the outside
or not shift to the big ring, depending on limit screws, no happy medium
available.

Same front mech with a 46/30 Sugino crank, ok shifting,
still would rub in the Big front, 2 biggest in the back.
Mech not happy with low bb on bike.

Shimano 10s GRX front mech, doesn't play at all
with Campy 10s, too much force is needed to move derailer.

IRD Sub-C front derailer, setup was easy, no dropping,
no rub in any gear combo. Hooray.
A worth CX-70 replacement.

Thanks Mark, I attributed it to the ti/carbon cages but will work on it a bit. Helpful advice!

Where are you guys finding all these small chainrings smaller than 39 teeth for Campy 10-speed doubles? I thought 39 was the smallest Campy made. Are you running 11 speed chain rings on 10-speed cranks? :confused:

Enquiring minds want to know.

Campagnolo introduced Compact (110mm BCD) cranks with 10spd groups, which allows chainrings down to 34 teeth.

Okay got it! I didn't realize the thread was talking Compact cranks. The BCD on my standard double appears to be more like 135 mm.

The cage isn't titanium..no titanium cages on Campag front ders..carbon and steel.

Aaaaaaaand it works. Updating my 1993 Extralight is almost complete: just waiting for a set of 23mm Dugast Strada tubulars and I'm ready to roll. Components are mostly from 2007 but 3ttt bars are NOS from the early nineties...

Absolutely lovely. That is clean and classy build. Love the color.

[LeMond123]

Like the stem coordination you got going on there!
Not always a fan of black components but to my eye this looks done right.

Thanks for posting this. Planning to run a 46/30 on Campagnolo 8 or 10 (TBD) and if the FDs I have wont cut it, I've now got something else to try (and it's silver, hooray!). On the test stand recently a 90s Athena was shifting 46/30 (no ramps/pins) pretty well, but turned out the (>1y old eBay "find") Racing T crank DS I was monkeying with had mis-tapped pedal threads (was "repaired" with backwards helicoil, thanks...). So I didn't get to actually ride it. Got another crank on the way to try.

[old_fat_and_slow]

Pardon my ignorance (again). What crankset is that on the Merlin Extralight shown? Looks pretty cool.

They're old (2004-ish) FSA Carbon Pro compact arms with 50/34 Stronglight CT2 rings and Tune titanium bolts and an FSA ISIS axle.

That’s a great looking bike...very unique.

[thirdgenbird]

I really want some bora 35s with the same decal treatment.
