I decided not to follow my own advice.
If you amputate "mobilebasic" from the URL, it will work.
It is anecdotal, with results based on 2 bikes, one rider.
The clear message from the testing is that we have no basis for saying that a new bike is faster than an old one. We dare not be as firm in claiming that the old one is actually the fastest. After all, the article is based on 16 shorter strokes ridden by one test cyclist.
To me, the answer is clear and obvious. The steel bike has a Chris King headset.
