Not _my_ claim Jan; that would be the common knowledge for the period between 1935 and about 1960. For example the first Campagnolo cranks (1958) were known to break and Cinelli didn't make an aluminum stem till 1960. Ambrosio had aluminum stems and bars in the early 1950s used by the pros, but it is easy to see in photos of the pros that steel cranks and stems were used clear up into the mid 1960s.

Vietto didn't race any of his Tour de Frances on an aluminum frame.

Yes and La Perle sold their version of Hugo Koblet's team bike with Stronglight 49D aluminum cranks, but Koblet won the '51 TdF on steel cranks (verified by photos).

I have a huge amount of admiration for Daniel Rebour but I wouldn't make the assumption that pro riders agreed with everything Rebour wrote. No different today with cycling scribes and pro riders.

Hope you didn't mean that to sound as snide as it does to me. I'm old, but not that old. My understanding of why sport riders liked the various T.A. cranks over the years was because of the unlimited choice in chainring teeth and configurations (single, double, triple, quadruple). I never cared for them because the foil sticker stuck on the crank looked cheap and the pros all rode Campagnolo. (Incidentally, there's no need for a devil's advocate on this list, unless you like arguing both sides of the question. <grin>)

Why would T.A. Criterium cottered aluminum cranks be popular in 1960? Because they were newer than new!!! Same reason people keep buying the latest and greatest today... its new and unique (for a while). In 1960/61 I was riding an English Racer (Raleigh with roadster bars and Sturmey 3-speed) to high school occasionally and was only aware of one crazy old man (old meaning in his mid 30s) that road a Schwinn with a derailleur for sport (that would be a ride of an unimaginable distance to me of 25 or 30 miles in length).

I'll end with your previous statement: "But I find that more often than not, what seems like stupidity or backwardness to us from a vantage point 50+ years later, in fact was done for good reasons. The racers weren't stupid, and their bikes were their tools of the trade. When something truly useful came along, they adopted it, unless there were reasons not to."

Anyone else what to share their opinions?
