campy has a compact drivetrain now...whats next? a splined BB? ha!

actully, it sounds like it is kinda stupid. it only works with their rings, and their system...

for what it's worth, there have been persistent rumours of campagnolo licensing the isis spline for a couple of years now... so who knows?

which is just like all the rest of their stuff, right?

and like shimano...

Looks great. Sign me up, as long as it's priced reasonably (ie not like the record carbon crankset)

I just loved the description. Part of the new front derailure "is shaped like an inverted "S" for increased precision."

Who writes this stuff? An inverted "S" is the same as a right side up "S".

to invert something doesn't necessarily mean to turn it upside down.

perhaps they meant a reversed S.

but we weren't talking about shimano, were we?

Thanks -- I learn something new every day.

I was waiting for the Ritchey compact crank. I can hardly wait till September!

Shimano standard road cranksets have a 130 mm bolt circle diameter which allows chainrings as small as 38t. Campy standard cranks are 135mm and allow chainrings as small as 39t. A compact road crankset has 110 mm which allows chainrings as small as 34 teeth.

The old standard for MTB was also 110mm for middle and outer rings and 74 for the granny ring but was later changed to an even smaller bolt circle that would allow a 22t small ring. 94/58 I think or something close to that.

I assume you are talking about a double only, not a triple.. In a triple the third ring bolts to the second ring, right?

on most triples, the granny bolts onto the crank down by the chainring arms....so a second set of holes, tapped for the chainring bolts are...uh....down there... at least, that's my understanding of how it works...

i'm not sure what the BCD for the inner ring is though...

74mm on every road crank that I have seen so far.

Unless its a TA, in which case there is an extra set of bolts for tiny MTB rings. They also make a 110 "compact" double, so TA rings should fit on the Campy chainset.

Glad to hear it. FSA does the only decent compact carbon chainset, it's time there was some competition to drive prices down and make others take note and make one (and some ally ones too).

So has anyone checked out the campy compact crankset? sssooo $$$$.
Any opinions? I'm pimping out a beautiful Team Miyata frame and decided to go campy (chorus). I need a compact crankset (Colorado). Should I just stay with FSA?

Nope, Campy compact uses a proprietary BCD.

I think it is a great idea to make a front derailleur designed specifically for a 50T or 48T chainring. FRom what I'm told the shimano road front derailleur doesn't work so hot with the 50T chainring cranks.....well it works but not as well as with the 53T rings.

That's BS!

The carbon FSA is nice and not too expensive. I think that Colorado Cyclist was selling the non carbon compact model on a weekend special a few weeks ago for less than $200. I use a Ritchey compact crank - old style with the square bottom bracket. No problems in 5 years and many miles.

The nicest compact crank I've seen is the Stronglight z'light compact (which I favor because it can be had in 180mm). I also don't have confidence in carbon fiber cranks.

P.S. Z'light compact is the most beautiful crankset i've seen......Suitable for a Campy REcord Drivetrain!!

If I were currently planning a Record build up incorporating a compact crank set (and I am), I would choose the FSA carbon compact with the new Campy CT front derailleur. The proprietary chain rings on the Campy bother me and the FSA is a bargain compared to the Campy crank set (I think I read something like $800. for the Campy). It will take some time for that price to come down a bit.

I've seen the campy compact going for @ $600. (And there's not much difference in price between chorus and record.)

So FSA with campt ct front derailleur and campy cassette would work?

Thanks.

I don't see any reason why the derailleur wouldn't work. The outside diameter of the chain rings will be the same for the Campy and FSA, so the relative drop between the small and large rings will be the same. I believe only the bolt circle/spacing may differ. Campy cassette will work with FSA crank set.
