Of course, there is the maxim, "If it ain't broke, don't fix it."
Which would apply to items like 7710 Dura Ace Track Cranks. But, I'm sure that if the sales projections were good enough, Shimano could make some improvements to them. Notice how they change their pedals (even ever so slightly) every few years as well as their other components.
I think that handlebars (sprint and enduro) are an "Area of Opportunity" for our sport. For example, look at how many different TT bars we've seen in Kilo/500M rides over the years vs drop bars for sprint events, yet there are more drop bar sprint events than there are aerobar sprint events.
...this is why those who can make their own drop bars...make their own drop bars.

As to Scattos, they may be popular, but they weren't the groundbreaking piece of equipment that started the narrow bar revolution. That was Nitto and Alpina. Scattos just made the concept sexier by being aero and allowing riders to use a flatter stem. A cosmetic refinement of the revolution, much like hiw Shimano redesigns and trickles down their pedals to lower groups. Functionally nothing is different, it's just sexier and newer and people are willing to pay for that.

“One good test is worth a thousand expert opinions.” ― Wernher von Braun
All I wanna do is test it out. I'll be the first to admit if it's stupid.
Very little progression has been made for consumer sprint-specific handlebars. Compare that to how much effort, engineering, and innovation (attempts) go into TT bars. Scattos are a hit becuase 3T tried something different....that was 7 years ago.
I wish I had the equipment to fabricate a set(s) for you. Not to disprove anything, but to facilitate the discoveries that are possible when going off the beaten path. I'll be the first to smile if I'm wrong when there is a positive outcome.

I think a few of you might like it when metal 3d printing becomes a little more accessible. These are some custom sprint bars for the Aus para team, somewhere in the low 30/high 20cm region.
3d printed titanium and can be as strong or flexible as you'd like

That sounds wonderful.
I can imagine even having them tweaked based on the athlete’s hand size, and as you suggest, strength.

One place where tweaking may help is in grip diameter. Small or large hands may benefit from variances away from the standard diameter. Could help those with smaller hands when it comes to explosive starts.

I've always wondered why we use the same diameter that was set by road bikes.
Barbells come in at least 9 different diameters, from 22.2mm up to 32mm: https://www.roguefitness.com/weightl...lates/barbells
Yet 125lb sprinters use the same off-the-rack sprint bars as 250lb sprinters. Just doesn't seem right.

FWIW in Olympic weightlifting women's bars are 25 mm in diameter, men's are 28mm, and standard powerlifting bars are 29 mm. So even though there are large ranges, the far ends of the spectrum are used for specialty purposes, like children or specifically working on grip strength.
3-4 mm of diameter difference is similar to the difference between using the thinnest Lizard Skins bar tape (1.8mm) and the thickest (3.2mm).

Given the price and shape, I'd expect them to be carbon. It's hard to shape aluminum that much.
Had I not just gotten some Scattos for Christmas last year, I'd be all over these bars.

The Dixie bars are carbon.

"Monique Sullivan sees beauty — and madness — in what athletes put themselves through"
Monique Sullivan sees beauty ? and madness ? in what athletes put themselves through - CBC Sports
I pushed myself in sport for 15 years, fueled by the desire to be the very best. After both the London and Rio Olympics, I walked away fully drained. It took me 18 months to recover from the build-up to London before I came back to training, and now, post Rio, I know that I have nothing more to give.

I'm not sure what it's called, exactly. But it's the time of year when a few Western riders race NJS Keirin in Japan for a few months.

I took my new steel beast for a spin today! I expected it to flex heaps and feel like a noodle but I'm stoked with how it turned out. I have my first practice race tomorrow so that will be the true test.

This is generally called "International Keirin" over here. They used to have special shorts for them but now it seems like they just wear the usual s-class shorts.

There's a YouTube series on this from when Shane Perkins and Theo Bos did it a few years ago: https://www.youtube.com/watch?v=Qyem...ature=youtu.be
