I recently purchased a 2009 Performance Scattante CFR Team Dura Ace bike as the price (including various sales and mark downs) was too good to pass up. The price was actully lower than the cost of purchasing (at internet discount prices) the good parts, e.g., Dura Ace components, Easton wheels, CF brakes and cranks, really nice CF bars and seat post. Overall, I am quite happy with the bike, though it is a bit heavy at about 16.5 lbs w/o pedals for a 53 cm frame.

This weekend I discovered part of why the bike is heavier than expected. I had occassion to remove the fork and I was shocked at how heavy it was. I suspect that it is at least 1/2 lb heavier than a high end fork. It is massive and uses an AL steerer. Thus, I would like to replace the fork, most likely with a Ritchey WCS UD model. The frame uses an integrated headset.

After poking around a bit, it seems the world of forks and integrated headsets is much more complex than I had anticipated. The bike currently uses an FSA headset that is marked as IS-2. My research indicates that this is likely a Cane Creek standard headset.

My first question is will there be any compatibility problems going to the Ritchey fork? It is designed for an integrated headset, but I'm not sure that all steerer's on 1 1/8" forks are really the same diameter. Also, I have not been able to determine whether bearing race this fork is compatible with Cane Creek headsets.

Is there a possibility I would need to replace the headset? If I do need to replace the headset, how can I determine which headsets would be compatible with this fork?

Are there any other issues I should consider?

Thanks,
Ira
