Quite like the look of these, some good attention to detail on the frame, thermoplastic CFRP with their own in house manufacturing, adaptable to 27.5, 29 and short and long travel variants by changing the swingarm and/or shock and adjustable geometry thanks to the headset fitting.

If they're as strong as they say then this is a game changer. The 2 videos on pinkbike are good. Geometry looks to be pretty much spot on and they're already distributed over here by shorelines in sheffield so we could see these frames pretty quickly
Read the PB article the other day - very interesting, the reduction in manufacturing time is impressive compared to traditional carbon frames.
I also like the modular approach with a common front triangle and swappable rear stay sets.
Be interesting to see what the price in £ will be.

Yep, would be interesting.
It's a really cool concept and, as someone who only has one bike, would be cool to add a seatstay kit to run different wheel sizes & geometry.
Will be interested to see what they go for when they land over here..
The PB article said the fragile weighs 6.5lb without a shock. Isn't that similar to aluminium frame weights?
Yeah it does seem a bit heavy. They do say that is a large frame but a santa cruz medium is between 2.5 and 2.7kg. The aluminium rear will mean it should be a bit more but I suspect the other reasons could be the slightly lower matrix properties vs epoxy and if they have used chopped fibre in places.
Add to that things like the headset arrangement could add weight and having one triangle designed for the burliest set up is not going to be optimised for the lower travel version.
They could probably shave another 10-15% off down the line as they learn more about the materials and there manufacturing. They look like a good bunch who know what they are doing and not afraid to try stuff.
Hmmm I do like this a lot.
Proper use of engineering.
Thermoplastics were around 20 years back from nytex in braided form we made lots of stuff out of them a few years ago we made 3d woven braid and thermoplastic parts....no one was interested due to the cost of the 3d braided preform...
See
One thing of note however you will break before it does
Where they co-mingled braids?
