comment How much speed can I buy
@Michael - While fit may not be the whole answer it is often a huge component. If money is no object (as you suggest) I would consider professional fitting in a wind tunnel. If you can reduce your drag coefficient, yet remain comfortable this could be huge gain, potentially much bigger than a lighter bike and aerodynamic wheels. How big depends on the pace you can ride at (the gains are multiplicative relative to speed). To me changing some bike specs such as weight and wheels is a very one-dimensional approach.

comment Always cycling in highest gear, why?
A couple points: 1) Whether or not you recruit your fast-twitch muscles depends on the total force being exerted. You can cycle at low force at a low cadence (and moving slowly). 2) You cannot exercise anaerobically for more than about a minute. A half-an-hour commute will primarily be powered by slow twitch muscle fibers.

@andy256 - you might want to consider having your biomechanics assessed. You may have alignment issues that are perfectly functional at a lower force, but problematic at a higher absolute force.

comment Long term benefits and risks of bicycling
Nice summary. A negative you might want to add: loss of bone density. Cycling is not an impact sport so you can lose bone density if it is your only form of exercise. Also body posture can be a negative and an be confounded if you sit a lot for work (hip flexers, IT band, back, shoulders, neck).

comment Why are so many technical aspects of cycling so subjective?
@Michael - Indeed why don't we run bigger volume tires? Many are trying to get more people on larger volume tires, but many modern road frames can't fit much larger than 25mm (although this has recently been changing with "all road" bikes). The pro peloton probably won't go much bigger as acceleration especially sprinting on larger tires is not as efficient (or so the story goes).

@azer89 - I agree, but who will pay for all this? Science is expensive and costs need to be recouped or future experiments cannot be run.

@ojs - The thought experiment is to relay that the one set of experimental results you linked (while interesting), is really one piece of the puzzle and may not give you the whole picture of "real world" performance. Perhaps all of Shwalbe's marketing is crap - sure it is a possibility. Or perhaps they were also basing it off a larger set of test conditions. We don't know. None of us know because we are not privy to the testing data. Often as more data is collected under many differing set of conditions our understanding evolves.

@ojs - Take an extreme example of comparing a supple narrow tire and supple large volume tire. Larger volume tire can be run at lower pressures, on rough roads this is a bonus as it allows for more vibration absorption and less suspension losses (losses associated with the rider vibrating on the bike). Under this scenario a roll down test would result in different ranking and relative differences. Overall there will be still be a correlation with the smooth roller test, but as the road gets rougher the correlation will likely lessen.

@ojs - I am not suggesting that there would be no correlation/association, but that ranking or relative differences between tires could change depending on the test surface (as you noted). Giving Schwalbe the benefit of the doubt, speed rankings on the intended use surface (perhaps they do a series of tests across different surfaces - I don't know). As marketing tends to favour simplicity, we rarely get all the information and are essentially left with anecdotal evidence.

comment Why is it easier to follow a cyclist up-hill
@RoelSchroeven the problem as you point out is that your friend is an unsteady rider. In a race situation I would ditch his wheel and find a better/smoother rider. In a casual ride like you were on you are kinda stuck with what your got.
