Campa Centaur triple and Engagement (Salsa) chainrings
My wife needs a little help in some of the tougher mountains here (not that I don't, but I'd probably never admit it).
Along those lines, I do find that after more than three months here, I am hardly ever in 30. Though we did 107 Km the other day, and were surprised at about 80 Km by a mountain I had not seen on the map. No way to go but up, and I used all I had and could have used more.
We have Campa Centaur 9s 30/40/50 triples on our bikes. I see at Branford's site that they have some inner rings that go as low as 24, and are compatible with some Campa equipment.
Question: is the 30 on our bikes 74 mm? The blurb at Branford seems to indicate that it is, but it isn't easy to measure without taking the bike apart.
Anyone have any experience with this mixture?
