Get a high end frame. A full dura ace kit. Put it together or have a shop do so. You'll spend 3/4 of the R4000 price.

Check what you could get with 3/4 the money on GVHbikes.com

Used the extra 100s on goodies.

Again, although controversial among some, I am a big believer that high-end production bikes are always overpriced. They are only worth it, if money is not an issue for you and/or you do not want to deal with the details of getting everything to fit (compatibility of components).

They are priced rather high for a Dura Ace bike. The best new deal I have found was at Costco. They have the R4000 & 5000 bikes at $2995 & $3495. You can also find the R4000 used in the $2000-$2600 range on this site, ebay, and others. I know someone that has the R3000 built with full Campy Chorus, Record hubs for only $1500. If you are intested I can get you in touch with him. Hope this helps.
Large chainring problem540nova

I have this bike, and love it, except for a problem I'm having with the large chainring. For some reason, under full, standing power (as in sprinting), the chain derails onto the outside.
There is no chain rub on the front derailleur, but the whole set seems to have about a 1 or 2mm wobble. I had the dealer replace the set, and the chainrings have been replaced twice, with little help. I suspect either the chainrings are somehow not designed properly, (refering to the ramps) or the BB shell is not square to the frame. The axle may also be out of true. What's strange is the wobble doesn't seem to be enough to cause this.
This last incident, Oct 12 2001, I was sprinting on a slight downhill, firmly in the big ring, when the chain just derailed to the outside, sending me off balance, and crashing to the road. I now have a broken pelvis, and a good amount of road rash.
The dealer is ordering me a new frame, new set, on which he'll install Dura-Ace rings, instead of the Cannondale rings, a new saddle, a new rear derailleur, and a new helmet, all at his cost (or Cannondale's).
It's my understanding that Cannondale has 4 versions of the Hollowgram set, (or possibly just the rings), the first with no marking, the 2nd thru 4th being stamped with MK 1, 2, or 3. Why would they have to make so many running changes?
I've been riding and racing for 22 years (Cat III), have managed bike shops, and am an aircraft mechanic for a major airline. So please don't insult me with follow-ups about the obvious causes! I know how to tune a bike, and what to look for!
