You might need that Centaur 124 after all, or the later "70-SS X3" triple BB, in 122 or 124. They all have the correct offset for triples.
Given the possible rarity of both those options, it might be quicker and easier to go with a Phil Wood.
Yep, striking out here. Found a 70x 124 Campy at a place in CO., but their website hasn't been updated since 2016, emailed anyway. Didn't find anything on Phil Wood, website, so emailed them, too. Waiting responses.
For the cost of this upgrade, I started looking at Mirage/Centur/Daytona triple cranksets. Lots in the 70 - 110 range , used in good shape, but another issue reared up. Need a triple BB, no problem, 70 x 115.5 is required . But some sites added that the BB goes with said triples and 32 or 35mm seat tube. What the @@#%$ . My Concorde 1990 seat tube is 29.2 or so . I don't understand what the seat tube width has to do with the price of tea in China, (so to speak). Also, there is the issue of using a 7/8 speed chain on a 10 speed crankset. Or 10 speed chain on 7 speed cassette. I'm trying to keep this bike Campy spec'd.
So, if the 70 x 124 spindle does work out, another dead end . I got the gear inches down from 39 to 32 going from a 26T to a 32T. Works good. The Athena RD is spec'd for a max 30, but a little fine tuning , got the 32 working just fine.
This is my favorite bike, was custom made, before retirement. So I restrict this bike to rolling hills to flats. My other bikes are Shimano equipped and lower geared. Hills, no problem, I love the climbs. KB
