Looking for 10sp Campy 39t middle chainring!
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 |

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 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. ~PB |

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. . . http://www.yellowjersey.org/c_rings.html Really, if you want that 135x39 ramped, email Peter White. -- Andrew Muzi www.yellowjersey.org Open every day since 1 April, 1971 |

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. Peter Chisholm Vecchio's Bicicletteria 1833 Pearl St. Boulder, CO, 80302 (303)440-3535 http://www.vecchios.com "Ruote convenzionali costruite eccezionalmente bene" |

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. ~PB |
