I agree that there are potential weight-savings to be made in those examples, but I think it's about getting the balance between stripping weight off and having something that will really handle the heavy power output. Richard Bussell's bike is a pretty good example of that.
It's this balance that is shaping up my build - for example I could have a Recon cassette as a lightweight component but it's likely it wouldn't fair well with the racing efforts required.

This is awesome - bravo!

Cool project. How much do the cranks weigh? I think the lowest hanging fruit right now would be to switch to Red BB30 cranks. They're very light for the price. You'll probably have to create a custom spacer to deal with the hidden bolt but I'm sure you could figure something out.

Would it be worthwhile to get a second gear clamp to center the cassette? That could potentially save watts with a straighter chainline.

@deek: Do you know how much the Red cranks weigh? I was considering a crank upgrade but maybe to allow running of a smaller BCD ring to save weight all round. Haven't really looked into this yet as want to get some other parts on the bike first.
@natefontaine: I've got another one as a spare and I think you're right - I'll have to experiment with the best way to run a split cassette!
@Budnz: I find no problem racing it without hoods. I wear gloves so it's good for about 10 miles before it gets uncomfortable. There's a bit of a gaping hole on the inside of the CX1 lever but it hasn't caused me any problems yet. When I'm out training/club rides I normally run it with hoods and drop bars, but no tape. Absolutely fine on the usual club run distances.
Thought I'd put up a parts list of all the weights. I'll update this as the build goes on.
