Pinarello has developed an alloy 3D printed frame allow the design to be custom tweaked to Filippo Ganna. "Aerodynamic performance, power transmission and comfort, all designed around Ganna’s “unique anatomy”, were the primary goals. "

All hail technology......

There's an odd sentence in the final paragraph: "While the unusual shape of the handlebars create a ‘drag
penalty’, they also reduce Ganna’s drag by a greater amount.." Does the 'drag penalty' refer to drag of the
naked bike? If so, it's irrelevant. Drag of bike+rider is what matters.

Clearly, that was the point the writer was making..

BTW, Drag isn't much of an issue at the speeds you can ride, Frank.

That's a reasonable assumption, can't really tell without further details.

> If so, it's irrelevant. Drag of bike+rider is what matters.

Yes, I'm pretty sure that's what they meant when they wrote "the handlebars create a ‘drag penalty’, they also reduce Ganna’s drag by a greater amount."

AFAIC the more intersecting aspect of the article is the implication of 3d printing a frame capable of the highest level of performance. If this is viable, custom 3d frame printing for the mass market seems inevitable. I personally know of several riders who have problems getting comfortable fits with standard frame geometries. Imagine getting measured for a frame, selecting optimitztion for either time trialing, long distance touring, etc, then having a frame delivered to your door. It wouldn't be hard to imagine the economy of such a program being competitive with the cost of high-end standard offerings. I'm sure Andrew remembers the panasonic PICS custom frame program from the late 80's?

BTW, let's try to keep the responses to troll defecations to a minimum, at least in this thread....

Oh, now the anonymous, cowardly scum ball, who told us he wrecked our threads because he liked it, wants his own little thread to be immune. That's the best joke in months on a notably humourless group, which means it is just the usual hypocrisy of the RBT Gang of Thugs, i.e. not funny at all.

Speaking of 3D printing, we're again reminded of humans'
endless creativity and innovation:

https://www.washingtontimes.com/news/2022/oct/4/new-york-changes-buyback-rules-after-man-prints-3d/

Which intimates that a firearms ban here would work
something like nuclear nonproliferation (which is to say not
at all)

In my humble opinion, technology has tendancy to ruin things. It so
often drives small independant low budget competitors out. I remember
watching the Can Am auto racing series die as a result of Porsche's
big money technology. It's happening in all forms of auto racing and
apparently bicycle racing, too. I see more and more of those swoopy
looking racer bikes out on my bike rides and I think they're as ugly
as the modern day Formula 1 cars. I guess I'm just an old fashion guy.

meh. Goes both ways.

In SCCA the Corvairs were still racing well against big
budget new machines in 1980. And no one pines for 'the good
old days' of gathering firewood and drawing a pail of water
to make the morning coffee.

If this is viable, custom 3d frame printing for the mass market seems inevitable. I personally know of several riders who have problems getting comfortable fits with standard frame geometries. Imagine getting measured for a frame, selecting optimitztion for either time trialing, long distance touring, etc, then having a frame delivered to your door.

It sounds nice, although I may be too tolerant to benefit much. I feel
quite comfortable on all my bikes, except perhaps the now seldom ridden
mountain bike. (That was built up piece by piece from a frame intended
for a different family member.) Two of the bikes were custom built, but
I still think I benefit from very average body dimensions.

But rather than manufacturing technology, I wonder if we need better
science in determining what bike fit actually works best for various
riders. I have one friend who paid a pretty high price for a fitting
session (Fit Kit or something similar) but wasn't extremely happy with
the result. And we have Tom, who seems to be constantly fiddling with
frame dimensions, handlebar, stems, etc. trying to get really
comfortable. It's always Tom's _next_ bike that's going to finally be
right.

Good idea. I see they're already here.

You're on to something there.

Humans are dynamic and skeletal dimension analysis can fall
far short of a 'comfortable fit' for many riders.

Yes, dimensional analysis doesn't always translate well. It can't predict biomechanical issues. It's just as necessary to watch some actually riding (much like analyzing a runners gait in order to get the orthotics correct). Still, for people without significant issues, I think something like a custom 3D frame could work well.

Delighted to hear that, Flunky. I wanted to be a standup comedian, but I wasn't common enough. Now you, you wouldn't have cut it as a standup comedian either. For a start, you don't have any wit, but in the main, you're just too, too common.

I just found out there is a category of software known as pose estimation that can infer a skeleton of joint motion from a video. There are a bunch of tutorials on OpenPose out there on youtube. I would like to use this for my disc golf throw but the software setup is a bit intimidating.

I'd imagine you need a relatively good camera as well. I was bit by the Disc Golf bug a few years ago. I'm fortunate that there are quite literally a dozen courses within a half hour drive from me. The Clement Farm course (Haverhill, MA) is two miles from my house, an excellent course that hosts tournaments on a regular basis. I'm not very good at it, but really enjoy it. I have a few regular friends I go with and we play "bogey" golf - that is, we consider it a successful game if we shoot 18 over par. IOW - we all really suck at it, but we have a good time.

Disc golf hasn't taken off much around here. It exists, but I don't know
many who play. What's soared is Pickleball. Our club's multi-year high
club mileage winner (over 10,000 miles in several years counting only
club rides, not individual rides) now rarely shows up for rides. He's
playing pickleball instead.

Interestingly, the injury frequency of our club members from Pickleball
is greatly exceeding that from bicycling. Falls, muscle problems, joint
problems, connective tissue injuries (tendonitis, plantar fascitis) etc.

Disc golf is much more gentle on the body overall, though some of the more technical courses could cause problems for people who have some mobility issues. Most of the courses around here are in heavily wooded areas and most have a few 'holes' that have very steep hills up or down to the baskets.

More on pickleball: Late yesterday evening the 10,000 mile guy I
mentioned above visited us on our back patio along with his girlfriend.
Talk turned to pickleball injuries. He listed many more injuries he'd
seen among people I don't know, some injuries quite serious. He saw one
person fall and break a hip, another fell and broke both wrists, etc.

I'm sticking with nice, safe bicycling!
