Any idea what amounts we are talking about? Also what would be the R&D budget that went into the "magic bike" versus that of, say, the "Madone 7", or the "P5"? Informed guesses welcome.

Good piece on British Cycling success:

http://inrng.com/2012/08/british-cycling-funding/

Quote:
The result of this is a British cycling programme funded at £26.39m ($40m / €33m) for the Olympic cycle of 2009-2013 or £6.5 million per year. By contrast the French federation’s annual budget is €15 million ($18.5 m) per year, which covers everything from head office to grassroots programmes as well as the elite programme. USA Cycling’s total budget is $11.8 million, again for everything.

To be clear, that is the UK budget for Elite cycling only!

Just to go off what I think eleviento is getting at, the bike is in some ways a contrast to the design of lots of engineering driven companies. Obviously they both follow the narrow is aero approach.

But just some examples on how their engineering differs:
UKSI has no the fork/down tube blending, whiich is incredibly common in aero bikes now
Whereas some companies "push" the top tube and down tube apart to create more headtube stiffness, the UKSI bike has them very close at the headtube juncture (this seems to be the weirdest part on the UKSI bike)

4) how they used CFD to create a super aero design, while Formula 1 teams funded by $100 million/yr plus are still trying to figure out how to get CFD to predict wind tunnel results

Maybe some of us believe too much in white papers, but someone else has been drinking kool-aid.

I worked in F1 for a couple of years doing CFD. The aerodynamics of a bicycle are much easier to model than the aerodynamics of an F1 car.

An F1 car is basically an inverted jet fighter flying at a large angle of attack with massive amounts of flap. The bargeboards generate vortex lift along the undertray. The large exposed tyres create huge wakes. Any time you have vortices you have very high flow strain rates which make basic turbulence models irrelevant. You have to model the interaction between the vortices off the front wing and bargeboards and how they interact with the tyre wakes with changes in ride heights and yaw angles. Then you have to model the diffuser and any stall and how it changes with ride heights. Then you have to model DRS systems when your purposely stall the wing. And then you have to model how changes in exhaust gase flow-rate through the diffuser affect the entire package.

Compared to this, designing a bicycle for minimum drag is a walk in the park.

Are these companies truly 'engineering' companies? Or are they driven to cut costs and increase profitiability?

The UKSI design suggests that you can build a front-end stiff enough using a 1" steerer with proper carbon fibre. If its stiff enough for Mark Cavendish, why are other 'engineering' companies stating that 1 1/2" steerers are a 'must' for satisfactory front-end stiffness?

Could it be that a larger steerer diameter on a fork is much cheaper to lay-up and manufacture?
