Thanks will certainly look at the fork/headset.

Canyon Ultimate SLX, tyres Conti 5000 tubeless 28mm

50km may not be super fast but hitting tar at that speed is the problem

Around 50km/h plus

I can say it is freakishly scary. But lets try the options mentioned

I seem to catch a speed wobble around the same area on a pretty fast decent, the bike goes into a serious wobble, the first time I used brakes to slow down but it actually made it worse so now I try peddle through it. What would be the cause of this and what can I do to stop it from happening. The bike is sized right for me so I am puzzled and pretty scared too.
