Is Colnago the last manufacturer to stay with 1"? Any rumors when they are gonna go 1 1/8? Seems to be the standard these days--nothing wrong with 1" as far as I'm concerned, but forks might be harder to find one of these days. Any rumors?
Lot of 1-inch bikes out there, but...cory

Rivendell (and its off the rack bikes, Rambouillet, Romulus, Redwood and Atlantis) are still using 1-inch, I think. At least my Atlantis has it. I sort of remember Grant talking about maybe going to 1-1/8 for logistical purposes, because parts might get hard to find, but I might have made that up. I agree there's nothing wrong with the old 1-inch quill.
As a practical matter, though, there are millions of 1-inch bikes out there, and a potentially big aftermarket for parts, so I doubt they'll disappear completely. But that's the same thing I said about 27-inch wheels....

My two main bikes currently are 1". I have had a couple of frames that were 1 & 1/8, I just don't see any benefit. Both bikes have full carbon forks on 59 centimeter frames and I still don't notice any flex. Why fix what already works?

Two reasons:
Many heavy weight riders, and racer types, notice flex in 1" carbon steerer tubes. Going to 1.125" increases the stiffness by about 30%. Also, the larger head tube allows framebuilders to use a larger diameter down tube than would be possible using the smaller head tube.

Regarding Colnago, Ernesto was quoted as saying that he will NEVER go to 1.125". Time will tell.

1 1/8 should be for MTBs only.Ahimsa

1" just looks more "roadie".

1 1/8 on a road bike looks clunky unless it has big tubes. But then, big tubes on a road bike look kinda clunky too, now that I think about it.

Down with clunky bikes! Down with MTB cross-over tech! Down with bike companies trying to fool us with false "improvements" that are really all about DFM! Down with marketing saturated phony baloney hoo-ha new fangled crap of all kinds!

Bring me the heads of the heads of both industry and state!

Stoke the fire Betty! We're gonna eat roast marketing exec tonite!

If the industry is going that way it seems that to buy a 1" bike is to gaurantee early obsolescence.

It merely insures that I can justify ordering custom steel forks and stems to my wife in the future.

"Well honey, you know I spent alot of money on this frame and it has to have a 1" fork...and the only way to get one nowadays is custom, so..."

Heh heh heh!
