172.5 triple road cranks vs. Q-factor

I'm looking for a set of 172.5 triple road cranks to run
with my Campy Daytona 10-speed drivetrain. The '03 Record
or '04 Chorus cranks are way too much quality (and $$$) for
my generic ride (Surly CROSS x CHECK). I know of FSA, but
they reportedly have very big Q-factors (distance between
outer face of crankarms). There are also several TA models
(thanks Peter).

Any more options with a narrow Q?

Better question - who has or where can I get a list of Q-
factors for 172.5 10-speed triple cranks?

Thanks in advance.

What Q-factor are you aiming for?
What chain line are you aiming for?
What clearance will you have for your smallest chain ring?
Zephyr arms, TA Axix 122mm bottom bracket - 153.5mm
Zephyr arms, TA Axix 125mm bottom bracket - 156.5mm

Zephyr arms, Phil Wood 123mm bottom bracket - 154.5mm
Zephyr arms, Phil Wood 125mm bottom bracket - 156.5mm

Zephyr arms, Shimano UN-72 122.5mm bottom bracket - 156.5mm
Zephyr arms, Shimano UN-72 127.5mm bottom bracket - 161.5mm

Zephyr arms, Race Face 120mm bottom bracket - 156mm

Zephyr arms, FSA 123mm bottom bracket - 158mm

Different BB axles have different tapers. Therefore the same arms will mount differently on different BB Axles of the * Same Length*

Sheldon Brown has a pretty complete table of Q-factors at:

I think that the Sugino AT Triple with 150 mm Q was the lowest I could find the last time I looked.

43.5 chainline

As narrow a Q-factor as possible, I just can't find the data
on the Campy triple cranks for comparison purposes.

I'm thinking 50/40/28 or 26 with a 12x25 or 26 (thanks
Veloce) 10-speed cogset.

My information sources (including Campy's official website)
don't indicate that a 172.5 triple crank is made other than
the '03 Record or '04 Chorus. Do tell more re Veloce...

Right. Mirage/Veloce triples and Centaur triples are
170-175 only.

Perhaps he was thinking of the doubles? 172 now in
Mirage/Veloce and Centaur.

Centaur $180, Chorus $230 not all that dear if you really
want the one-spoke-thickness-longer crank.

Personally I can't tell 2mm under any conditions.

YMMV, Princess.

Sorry Jeff, I was mistaken (looked up double instead of
triple). Apologies for raising hopes and wasting time.
