I rather enjoyed the letter from Jerrold Tiers of Clayton, MO (part of the St. Louis area). It's a shame that he didn't provide some of his credentials, so we might know whether he is credible or not. I'm an electrical engineer, and not a mechanical one, so it seems like crank bolt torque is one of those basic things that the engineers at the crank manufacturer would be able to provide a definitive answer for. It's hard for me to understand how the matter of correct bolt torque couldn't have been settled long ago.

... of course... back in this era, I don't recall many folks even having a torque wrench. Did bike shops even have one?? When I tightened the bolts on my Stronglight 93, I usually used a 3/8" ratchet. With that, I'm not sure I could have over-torqued it even if I had wanted to.

Probably the most inaccurate method to measure bolt load is by measuring torque because its dependent on thread flank size, shape, surface finish and about 25 other attributes. Studies have shown that experienced mechanics are better using their skill or feel to deterine if a bolt is properly tensioned.

Looking at the Vittoria cycling shoe on the ad makes me think I'd might be very reluctant to even use those shoes on the bike, lest I ruin their perfect sleek looks when the sole and the cleats get all rashed up from getting walked on.
I don't think I'll have the same problem though with the Le Coq Sportif brand shoes on the other ad.
The two shoe brand ads really shows how different the French and the Italians looked at their designs....
The Vittoria ad seems to almost zing the Le Coq Sportif ad, whether intentional or not.....

I remember tires with raised centers like in the IRC ad. I was sold on that in the day. Amazing how much better tire tech is these days. But for looks, I wish I could find a good quality raised center tire these days.

the soles on those Vittoria shoes are nylon/plastic, so no great loss if they get scratched up. I do love the perforated uppers, and am glad that those didn't suffer in routine use!

I do have a pair of shoes that I won't wear/haven't worn just because I don't want to scrape up the soles in everyday use. They are just too pretty!
I got these about 20 years ago, and they are still in the box.



Fortunately, I have other vintage shoes that I can use without worry.
