It's also unfair to compare people hacking together an aftermarket solution to a 100% in-house designed one like Magene has here.

I didn't mean to compare someone using a groupset as intended by the manufacturer with the tinkering of shigura - that's why i said that those tinkerers are aware of the.. limitations. Still I remember reading from someone who had to abort his ride and limp home because his brakes were getting really weak...
I only wanted to make the point that a too small reservoir, especially if maybe some other conditions happen to be met, can indeed lead to brake failure. Magene should absolutely design their system that this is impossible though and that's hardly rocket science - I'm looking forward to hopefully conclusive findings on what happened some time down the line.

On recalls: Kudos to Sram for owning their mistake then, that makes me feel reassured as I'm mostly using their stuff - the example of Shimano was just to illustrate that it's not an exclusively Chinese/Magene thing to go "No, there's nothing wrong" and putting people's health at risk with it. Now reading (thanks for the info Justin) it's actually now happening again just leaves me speechless.

Wow, thanks a lot for all the answers! This paints a much clearer picture of what is going on there.

Gonna have to have a think on what to do I guess, and whether the (not too big) savings will be worth the anxious wait for me, I can totally feel you Gianpy.

It feels like a different thing for wheels and frames, with the price delta being much higher and duty prepaid giving me peace of mind there (whether that's entirely justified or not..)

But yeah, thanks alot Still very new to this, still learning.

No experience with these in particular, but I got to test-ride the 6-spoke-wheels made by bike-ahead (probably heard of them since you're in the EU) on a hardtail. They were so stiff it wasn't even funny - I've never ridden such an uncomfortable wheelset before and this was on really mellow forest singletrack with hardly any gradient, so ~15-20kph max. I wouldn't want to ride them anywhere fast and/or technical. Had someone told me before a wheelset can change the ride quality this massively, I don't think I would have believed them.
Also, if you damage a rim, the whole wheel is kaput. Which is obviously less of an issue with these, since they probably won't cost 3k

If you love the style to head to the ice cream parlor, go for it. For 'real' riding, I'd steer clear of them - uncomfortable, badly tracking on off-cambers (too stiff), fatiguing. Obviously, that's also a matter of personal taste, but I'm on Vonoa Spoked Wheels now (Newmen's) and happy with these, so I don't think I'm being a total wuss there. It's probably kinda like the other extreme to textile spokes - love them or hate them.

Edit: Just noted this is the road section - but the wheelset you linked is an MTB one, so I hope my observations are still helpful to you - but even if you use them on the road, they'll still be on the "very stiff and not comfy" end of the scale.

The currently 'most extreme' XC bike that I know that is being ridden in XCO is the Arc8 Evolve FS, which has a HA of 65°. I have test-ridden it myself, and the very slack head angle doesn't help handling in slow, tight corners. The faster you go, the better it works. I liked it, but I'm not a purebred xc rider. My current bike (Mondraker Raze) which is 150/135 has 65,5° and would be classified as Trail/All Mountain, to put this in perspective.
These new geometries shouldn't be combined with stems longer than 50mm, and the fork should have a lower offset (normally 42 or 44).

Seat angles are a mess of its own, since companies have various ways to measure seat angle (the actual tube angle, the real angle at stack height..) and while their diagrams sometimes let you work out which one they mean, I would always take seat angles with a pinch of salt. For general reference: 75-76° is quite normal today, I have seen extremes of 78°+. My current bike has an 76,5° SA (72° real tube angle) and it works good for me. A bigger rider with more seatpost out might find himself further to the rear than he'd like, as the seat angle slackens the higher you go. Also, it depends on your crank length (shorter -> further back), obviously on your anatomy and your preferences. The old "knee above pedal axle" bike fitting method also has to be dropped with such seat angles.

Having started mtb on an early 29er XC bike with 69° HA, the ride characteristics of the current bikes are vastly superior. Much more stable, much less prone to OTBs. Obviously, dropper posts also play a major part in this - no more hanging off the back. What would have been an downhill/enduro bike geometry 10 years back is downcountry now. So you have a much better bike on the downs (mind you, with less suspension and durability than an enduro, so you shouldn't ride it quite like one) without really giving up anything for it on the way up.
