In reply to Lord of Starkness:
> Given the attitudes prevailing back in the day, it's open to speculation whether Anquetil and Merckx were 'clean'. Amphetamines and caffeine were pretty rife in the Pro Peloton in the 60s and 70's - however their records should certainly be considered valid as they were riding the best equipment available in their day and were competing on as near a level playing field as their contemporaries - as were Indurain, Moser and Rominger.
Oh that is such tosh, PEDs do not create a level playing field as the benefits or gains are disproportionate.
> Obree and Boardman showed what was possible by 'pushing the equipment and technique' envelope - however very few people have the physiology to ride in the exaggerated superman position.
Yes, we know all of that but there remains the question, I invite you to look at the data in the book, that Boardman doped for his final time.
> I do hope that Jens sets a good mark, and encourages the likes of Spartacus, Wiggo and Tony Martin to test themselves.
Yes and so do all of us but I'm far more interested in whether or not Tony Martin beats Wiggins.
