This is a very cunning design. Doesn't look like it would need very much more development to make it quite neat and marketable.
Bump?
This would be really nice for my commute actually. Over 30kms I get tarmac and gravel as well as some very sketchy single-track. It would be nice to slacken off for the single-track.
It's a neat design, but it's a bit like lock-outs on forks; you're sure you need it when you buy them, then you realise that you never use it (or you do use it, then realise that you've forgotten to unlock it halfway down a descent).
I'm still running some old U-Turn Rebas and Revelations. Brilliant system, I'd take that over fiddling with headset bearings out on the trail.
Be good for companies when testing new models, being able to adjust head angles very quickly would surely be a boon. Even for dh racers, adjusting angle for different runs might be useful.
My only slight misgivings would be about how they've retained those pins with a velcro strap, I'd rather see it using something like sprung index pins or better yet being adjusted back and fourth with a locking Cam mechanism rather than resting on a pair of pins in shear...
Also they only proof load tested their weakest component to a multiple of it's (calculated) highest load, they didn't manufacture multiples and test at least one to destruction to establish an actual failure point/load...
But as a student project it's a goodun, it demonstrates lots of stuff you'd be looking for in young engineers, development of options and ideas, a good understanding of practical substantiation, manufacturing, testing and inspection methods.
Plus their little video shows they can present their work quite effectively too.
Not a bad project IMO...
Poll results suggest that PB punters aren't sold.

4000 people would have a use for it, 2000 wouldn’t. That’s a pretty good hit rate!
I can’t see this being mass-market but it’s a great R&D and racing tool.
1800 of those say they would try both and settle on one - better off with a fixed angle adjust headset for that. Useful if you want to toggle between settings, but not many seem to want to.
Why would you ever want to steepen your head angle? I've never missed a steeper ha on my more modern bikes, mtb or gravel.
With longer forks and bigger Wheels and some massive head tubes about on bigger frames nowadays i for one don’t have the stack height to give up for that (650*2.6, xl frame w. 170mm ht)
Interesting to see they used the oneup preload kit outside of the stem. Did wonder if it would work like that.
