I have to say I am put off buying these bikes because of the bottle bosses.

I also can't explain why.
I lathed down a set of bolts for a ccx bike just because I knew the bosses wouldn't be used. I think it turned out pretty clean....
The off-the-shelf top of the line Colnago cyclocross bike has water bottle bosses. At least the retail version does. Not sure what the version used in the World Cup races would use.
I sort of get the aversion to them for the folks who buy the bikes. I feel similarly about fender bosses on my race bikes. It wouldn't be a race bike if they were there even though nothing else would change. Lame, I know.
And I'm a huge fan of bikes with fenders.
Just not on a pure race bike. I dunno why. Vanity.
It's sort of funny, because some folks got their panties all in a knot when that FireFly Ti "commuter" didn't have braze-ons for fenders,
and said "it's not a commuter bike".... so apparently the presence, or lack there of, certain braze-ons can change the definition of a bike!
I was just going to post a similar quiestion. I have a generic carbon Ebay cross bike that I use as my rain bike (used to live in Portland.....fun to get the stares down here when it rains). It has only one set of bottle bosses (downtube). I'd really like to mount another cage as one bottle on a 3 hour ride isn't enough for me. The seat tube isn't round, rather sorta aero shapped with some cutout for the rear tire so the basic hose clamp won't work.
I assume the bosses on the production bikes are aluminum and epoxy bonded to the frame. I'd like to purchase a set (have West Systems epoxy already) or would entertain other ideas.
