Ok, ok, the $5500 price tag is a bit steep. However if you are looking for a new Superbike this is probably one of the top 3 fastest bikes (amongst SC, Felt/Cervelo). At first when I heard the price I thought it was crazy, but now that I have thought about it it isn’t that bad a of a deal.
You take the $5500 and you get a S-Works FACT crankset that runs ~$650-700 plus you get your integrated aerobar (probably run ~$1000 for a 3T Ventus). So I think a fair assessment is you get ~$1500-1700 worth of value in the crank and aerobar. Just for reference:
P4= $4600 for just the frameset
Plasma3= $4000 for just the frameset
SC= $4700 for frameset + aerobar
Trinity Advanced SL= $4000 for full module like the Shiv
Felt DA= $4000-4500 for just the frameset
So really a $5500 Shiv minus the $1500 in extras you get put it fairly competitively amongst the other frames it is competing against. The Giant seems to be an outlier compared to everyone else as I guess it offers the most bang for the buck, but the styling and aero design is a bit suspect to me still. With the Shiv you obviously lose the ability to source your own crank/aero bar for your build.
The P4 seems to be the outlier the other way in being a bit more expensive than everyone else and giving you less for it. Take the Plasma3, Felt DA and add a crank + aero bars or take the Trek SC + add a crank and you are getting very close to the same cost as the Shiv. Obviously you could cut corners and buy a component of lesser quality, but if similar to the Shiv I think it would price out in the same ballpark, +/- $100/200
