Compact cranks - chainring source?

[Alan Simmons]

I'm getting ready to convert a 9spd Dura Ace drivetrain to an FSA
compact crank, and while the cranks are everywhere, no one seems to
have the compatible 110BCD chainrings. Are replacement rings readily
available?

Also, does anyone have any idea if Shimano is going to produce a
compact crank?

Thanks,
Alan

Huh? 110bcd chainrings are readily available thru a variety of sources
including, but not limited to, esteem newsgroup dealers like Sheldon
Brown (http://sheldonbrown.com/harris/chainrings.html#110
Andy Muzi (www.yellowjersey.org)
Peter Chisholm (www.vecchios.com)
or gasp!, may be your LBS!

Also, don't forget to look at thethirdhand.com and biketoolsetc.com

AFAIK, the only Shimano "compact" double crank ever made was the
RX100.....

Uh-uh... RX100 was 130mm BCD (130/74 on the triple). RSX was 110mm
BCD.

I've got a box of 110mm BCD chainrings in various tooth counts, but
you can't have any. I've been collecting them since 1978.

No compact crank from shimano. 110mm BCD rings are easy, from me, Andy Muzi,
Sheldon Brown. If yer LBS doesn't have them , can't find them, they are bein'
lazy.

Part of the whole reason for 110 BCD! (What the $#*& was Campy
"thinking" when they decided to come out with another bastard size?) I
think Excel Sports carries Sugino up to 50-tooth.

Out of curiosity, might Sugino make FSA's stuff?

the sizes used on new cranksets. Fortunately there are
seversl makers. Any LBS conversant with touring bikes will
have a selection.
FSA is a manufacturer. Sugino doesn't make their rings

they are 110mm, just with a hidden spider on all three cranks.

So they are 110 BCD with no hidden tricks? TA chainrings would fit the
Campy CT cranksets?

Like you, I haven't seen them in person but Storino and the boys at Velonews
say they are 110mm BCD.

Where does velonews state that the new Campy compact ct crank has a 110bcd?
Searching Velonews, I've only found 2 articles about Campy's compact crank:

On April 28, 2004, Velonews published a press release, from Campy, about the
compact crank, no mention of bcd:

http://www.velonews.com/pr/prn/articles/5973.0.html

More recently, on September 2, 2004, Velonews again published a blurb (sp?)
about the compact ct crank and still no mention of bcd:

http://www.velonews.com/tech/report/articles/6888.0.html

So, where does "Storino and the boys at Velonews say they are 110mm BCD"?

talked to the boys at Velonews, thetre are in Boulder, come into the shop from
time to time.

Ya know, call Campagnolo-

Peter Chisolm says the CT chainrings will be 110. However, the Campy
site says: "La guarnitura Campagnolo CT sarà prodotta nelle versioni
Record, Chorus e Centaur e ogni versione sarà disponibile nelle
dentature 34-48, 34-50, 36-50 con pedivelle da 170, 172,5 e 175 mm.
Gli ingranaggi sono specifici per guarnitura Campagnolo CT e non sono
compatibili con altre guarniture."

The Italian is easy enough to understand. That the chainrings are
"non sono compatibili" with other cranks seems to suggest that they
are a non-standard size. Maybe Campy is only talking about other
Campy 135 cranks. Who knows.

Cyclingnews.com reported back in April: "However, Campagnolo's CT
cranks aren't 110mm. Campagnolo wanted to change the design of its
carbon crank as little as possible, so the bolt placement on the crank
arm is in a different position from the other four, which means only
Campagnolo's own rings will fit."

Hey, I hope they're standard 110, but there's some info. to the
contrary. We'll see soon enough. When is the release date?

Ok, ok...finally a call to campagnolo USA and they had the sanswer.' The carbon
compacts fron Campagnolo are NOT, repeat, NOT 110mm BCD. When I asked what they
were, Dave at Campagnolo, USA said they were 'larger' but did not have the
exact measurement.

Sorry for my mis statament previously, but garbage in, garbage out.

NOW, lets get back to 'bush and his crashes'!!!!

Isn't proprietary technology the sort of thing you usually criticize
Shimano about?..:)

This news is going to make me shy away from this crankset. The TA or FSA
cranksets are sounding like a better way to go. You can just predict that
in 10 years when bicycling fashion moves away from compact cranks that
replacement Campy chainrings may be tough to find.

yep and I never said it was a good idea. I don't like the 130 vs 135mm hoopla
and I'm not thrilled about 112mm BCD either BUT at least Campagnolo is
'listening' and will have these, and hopefully aluminum versions of these
cranks as well.

shimano and DA 10s still has no triple..no compact..I guess DA is only for
sponsored racers, not us .5 of a century and .1 offa ton riders.

I'm a big Campy fan but I have to agree with you. There are plenty of
110 bolt pattern rings available. I also think that an ISIS bottom
bracket will be much more of a standard than the Campy ISO, square
taper.
