The issue is one of material hardness. Back when Colnago made those tube shapes the material was only slightly harder than warm butter. So they could draw a round tube, put it in a die and squeeze it and get the shape they wanted. If someone wanted to hydro form a modern high strength steel such as 853 or 953 they would have a very tough time of it. This means that to draw steel into a shape similar to what we see on carbon aero bikes that they would need to use a lower strength material and then use a thicker wall to compensate. I don't see any of this as impossible and at the same time I see very little market for such a bike. dave |

I'd be really interested to find out whether there are more medium+ end (Ultegra level or higher) steel than titanium bikes being sold. My guess is steel over ti.

Snip:
Nitpicking: If it starts dumping the moment the faster rider gets home and the slower rider gets back 10 minutes later, completely soaked and freezing -- that would seriously impact the latter's enjoyment of the sport. |

At five seconds per mile? 10 minutes? You're 120 miles away from home and it starts dumping rain and you don't have any bailout options?

I don't pay attention to bike industry trends, but a couple of years ago, steel was making a comeback in upper mid-range bikes. There was a slight up-charge over the same bike in aluminum.

Shee-it, my math sucks so what do I know? I did understand the premise though...I think. Last edited by Bob Ross; 03-24-2024 at 10:29 AM. |

If you're 12 miles from home, a delta of 5 seconds per mile is 12*5=60 seconds. |

So, if the riders travel at roughly ~20 mph, then at a difference of 5 sec. per mile the the slower rider would be 10 minutes and 3 1/3 miles behind the faster rider at the end of this 6 hour ride. Or if the faster rider didn't take up 10 minutes before they start riding explaining how his bike was 5 sec. per mile faster, they would both finish before it started raining.
