TA make a 110BCD crankset (the Zephyr Light), Rivendell still have stock of
the Ritchey 110BCD double (made by Sugino) and also another Sugino 110BCD
double. You can get five arm 110BCD splined spiders to fit MTB cranksets
that have a removeable spider.

Why do you need a 50 or 52? 48-11 is almost exactly the same gear as 53-12.
I use 48-34 chainrings with an 11-23 10s cassette for road racing and 13-29
cassette for pottering around in the hills. And the Daytona derailleur has
no problems with the 29t rear sprocket.

I just saw an article about Tyler Hamilton using a 110 bcd crank with 52
x 36 chainrings.

I am interested in a similar setup (110 bcd double) as where I live it
is very hilly and I am interested in doing a few 100+ mile rides with
10,000 ft of climbing. I am currently running a Campy Daytona 9sp double
front derailleur and a 9 speed double Daytona rear derailleur. I have a
clamp on front derailleur. Is it possible to run either a 52 or 50 and a
34 inner ring with this set up? I would prefer not to have to go the
triple route due to cost.
