Compact Crankset with Campy 10sp

This summer I'm taking a bike tour of the Alpes during the Tour de France (crazy! ). I'll be running Campy Chorus 10sp with a 13-29 and I want to use a compact crankset (such as the FSA Carbon Pro Elite Compact) with 50/34. Will this crankset work with a Chorus medium-cage rear derailleur and a Chorus double front derailleur? Thanks for any help you can provide, and if you can recommend a good place to get a deal on the cranks, that would be awesome! :

It's my understanding that you would need a different bottom bracket, either
the Isys (sp?) drive or the Dura Ace to fit the FSA crank, but that
otherwise this setup would work. However . . . I've thought of this too, in
connection with a planned trip later this year to the Maritime Alps, on a
Chorus 10-speed bike I use, and I've concluded that it's not so hot. Sure,
you get the 34/29 as a low gear, but you're stuck with a 50/13 as your
longest one, which will spin out pretty easily on a slight downgrade or with
a tailwind. With Campy Chorus, I think a better setup is to convert to the
Campy Chorus triple, new this year. (The Campag. front der setup is much
better than Shimano's because it is so easy to trim. I have the Record
triple on a bike I use for traveling and I find it trouble-free.) You won't
get the 200g or so weight advantage from the FSA compact crankset, but you
get a potentally lower climbing gear without sacrificing at the top end. In
fact, with a 12-26 on the back, you can even improve the top end over the
13-29 cassette. You might fit a 52 or 53-tooth big ring onto the FSA crank,
but I would be leery of the 18- or 19-tooth drop/rise for changes at the
front. Small to big changes will be slow, and big to small could,
literally, suck.

Yes. I just built that:

I couldn't email the address you used so write if you want
to pursue this.

Sure, w/o problem. Just put in the BB, the crank on, lower the front der...go
ride.

ISIS or any shimano Octalink in 109mm length, from DA thru 105 level-

I have used a 50/13 tallest gear here in Colorado, on ups and downs w/o
problem. It takes more than a ''slight' downhill to make me 'spin out, be in
excess of 110 rpm, where I would probably go fatser if I stopped pedaling and
thought aero thoughts.

BUT get the 'Tyler' crank with a 52/34 then, that'll work fine also...

It's easy to make a 13/29 into a 12/29. Downhill, it's not difficult
to spin out most normal combinations. Spinning out a 50/13 in the
flat or even slighlty downgrade is exercise. In 9sp days, a popular
Campy combination was 53/39 and 13/26.

I wouldn't invest $4-500 on a drivetrain for a particular trip. I'd
borrow or buy an inexpensive Shiman hubbed wheel and put on a 11/32
cassette.

And I thought it was 52/36. I wonder what front derailleur he used
and how great the shifts were?

I think that it will work no problem. Try it. When you set it up,
adjust it so you'll have enough chain to go into the 50-29 w/o
problems. You don't want to run a chain that is too short and
accidentally shift into the 29 and destroy your rear deraullier at the
top of a mountain pass. You may be running a chain that is too loose
when you shift into the 34-13 through 15. right now I am building a TT
bike using an old 110 crankset and puttung 52-34 chainrings.

I don't know what sort of shape you're in but, if it were me, I'd do it
right and go triple. Having that granny sure makes hill climbing easier!

I just came back from a week of riding in the Australian Alps - climbs
and descents up to 30km long. I was using the exact same Chorus medium
cage derailleur and 10s 13-29 cassette with a Sugino PX crankset and
42-28 chainrings. I think there should be enough take-up on the
derailleur to cope with the two extra tooth difference of the 50-34.

If the descents had been straight and not very steep I would have
found the 42-13 top gear too low, but there was very little of that.
Most of the sections of descent that weren't constantly winding were
so steep (mostly around 10% or 11% and up to 16% in places) that
getting into a tuck made more sense than pedalling. And on the winding
sections, a few pedal strokes out of each corner at 140-150 RPM in the
42x13 to get up to ~60kph and then back into a tuck for a few seconds
until braking for the next bend. IAK, going down mountain passes fast
is mostly about being able to corner and less about having a huge gear
to pedal the straights. And I certainly appreciated the 28x29 low when
climbing the 16% gradients.
