Anybody know what the bolt circle diameter is on the Chorus ultra-torque compact cranks? Is Campy still going with a weird BCD on their Chorus/Record CT cranks?

This thread so old...

I think the answer is "2007 Chorus and Record compact, still not 110 BCD"

_but_ what I want to know is which Campy compact cranks _are_ truly 110 BCD? Centaur (and below? is there a Veloce Compact?). Just the square-taper era or the Ultra-Torque jobbers as well?

Hmmm?

Not to put too fine a point on it, I want Ultra-torque bling for a, uh, little project, but I don't wanna be stuck with just Campy rings.

I recently bought a Veloce compact (square taper) on closeout from Trashbar. 110 rings for sure. And $100. Great deal.

On all carbon Compacts the crankarm bolt is offset to Campy's proprietary 112mm,all 4 other bolt holes are 110mm.So if you want to run after market rings get out the shaper or round file and rework the crankarm hole.2006 Centaur square taper used 110mm,I do not know whether or not the 2007 Centaur Ultra Torque compact crank is 110 all around or also uses the offset 112.Licktons says it is 110 bcd,Texas cyclesport (when asked says "its different") Maybe someone on this forum who actually has one could answer
