Looking for 10sp Campy 39t middle chainring!

[John Crankshaw]

I'd like to get a 39 tooth middle chainring for my triple crank, Campy 5-135
bolt pattern. Must be pinned, of course.

Found only one source: Peter White Cycles.

Any other sources out there?

John

Don't assume that the middle ring must be pinned. When the 42 went on
my Racing-T, I replaced it with a standard, 42t ring that was the 2nd
ring af a double. It shifted fine. When I put the ring on, I had
forgotten that I needed a ring with shift assists. Turns out I was
wrong.

For reference purposes, the rings were 52/42/28.

When you do put a 39 onto that setup, there's a likely chance that the
front derailleur will hang/scrape on the 39t cog. You can get a DA
triple front derailleur or change to a 53t big ring and have the front
derailleur about 4 mm above the ring.

I've used 39 and 40T unpinned TA rings with my Campag 9-speed chainset and
Ergos. I wouldn't call shifting "fine" but it's tolerable. The middle
requires a bit more overshifting than a pinned 42T ring to get up on it.

How many sources do you need? Peter's a highly reputable dealer.

Well, if he thinks Peter is not *enough*, I recommend the following sources:

Sheldon Brown
http://sheldonbrown.com/harris/chainrings.html#135

Andy Muzi
http://www.yellowjersey.org/esoteric.html

and don't forget "Campy Expert" Peter Chisholm
http://www.vecchios.com/

Of course, any LBS can order 135mm bcd chainrings too....

Peter most likely has your first choice ring.
I don't.

Today in 135mm x 39t:
Black Spire titanium color 'hard coat' $39.95
Record '90s type no ramps $69.95
several Stronglight silver $39.95
several Vuelta silver $29.95
(Vuelta are not top quality rings)
none of those are ramped.
I have one lipped ( It isn't really a 'shift gate') TA Pro
in bright blue anodized $44.95. Cute plastic display
package. Yes I have the matching outers, red or blue.

If you can substitute a 40tt I have current Record Ten at
$79.95 with pins and ramps or Veloce at $34.95. But you
probably have that already, right?

As happens so often today, there's a few hundred dollars
worth of merchandise and _still not_ what this customer
requested. . .

Really, if you want that 135x39 ramped, email Peter White.

Yep, we have them or can get them 39t and TA...'may' see some shifting issues
tho, getting the chain off the 39t to the small ring. A shimano triple front
der sometimes helps...DA type.

I have no difficulty in shifting down to the granny from my 39T unpinned
TA ring with a Daytona triple derailleur, but an extra click of the Ergo
is required to shift up to it, then a correction afterwards. (I found
some overshifting was required with standard Campag stuff but one more
click with a TA ring).

This is just a minor annoyance rather than a big problem.

I'm not going to confront the obvious "paralytic fear of e-mailing Peter
White directly" issue here. Rather, here's a link to Peter's webcam,
trained on his shop. A discerning eye might be able to find said ring
within his inventory. Wait for it . . . wait for it . . . ahhh, there it
is.
