Range of chainring sizes for Campy cranksets
What are the smallest sizes available for outer and middle chainrings for 135BCD Campy crankset? I have a Campy Centaur Triple that is 52/42/30 and I would like to go 48/38/26 but I'm not sure if those sizes are available. I've seen 49 and 39 from Harris Cyclery but they are pretty expensive. What are some good sources to find Campy chainrings?

Anything CampI is expensive. I'll have to double check but I think 39 was the smallest for the 135 BCD. CampI usually listed, but try finding, every tooth from 39 to say 56ish.
Sometimes you can find like a Strongligh or Ofmega brand to fit CampI

Wiggle copy says:
which is the same alloy Campag themselves use to machine their chainrings ..
TA only make their chainrings from the best 7075 T6 heat treated aluminum sheet.

[h=2]1977 Diminutivi Campagnolo[/h]
Campagnolo is now a well-consolidated company and its relations with countries other than Italy are growing on a daily basis. Like anything that becomes familiar and well-know, people began to come up with company nicknames. Thanks to its popularity in English-speaking countries, the Campagnolo name became, over time, abbreviated to Campy in publications and correspondence. This prompted the decision to register and protect the nickname, making it an integral part of the Vicenza-based company.

The greater public's version won out over time.

I prefer CampI. I also use the ever popular Campagnola and Campagranolo LOL I just do it as goof like how they used to have the hooligans in the old movies mispronounce big words.

Appropos of nothing, I remember those halcyon days of the mid-1970s when I could (and did) walk into Talbot's in Sam Mateo and see, among all the other goodies two stacks of chainrings for sale, one Campy NR and one Shimano 1st-gen DA, in any size you could possibly want. They had at least one in every size from 39 (DA) or 42 (NR) well into the 50s. Them's wuz the days, by crackey . . . .
Now get off my lawn.

I figured out that changing my chainrings is equivalent to going from a 12-27 rear cassette that I currently have to a 13-30 "century special" that is offered by Harris Cyclery at for $126. Are there any benefits or downsides for one option over the other?
Thanks!
Thanks!

If you are willing to live without ramps or pins, these chainrings are fine:

you get tighter spacing on the smaller casette (13-29 lacks an 18 cog) and/or perhaps delay the shift to the big ring
Campagnolo branded cassettes have synchronized shift gates and ramps for almost instant and silent shifting
as a tangent if you do want a new Cassette, order it from the UK.
Ribble has galvanized Veloce cassettes including the 13-29 for $42.61 not including the current 10% off sale.
Nickel-chrome Centaur cassettes are $57 for 13-26, $89 for 13-29, and $92 for 12-30.
