Hello forum, since some time I have the problem that at approx. 90 km/h my front axle “flatters”. It actually feels exactly as you know it when the brake discs have an imbalance. However, it is independent of braking because even when driving normal it is available from approx. 90 km/h and disappears from approx. 100 km/h again. I only got TÜV two days ago and can say that the examiner really did his usual tests and apparently none of them I can’t connect it to the lowering because the problem existed before and occurs even if the chassis is in “high” mode. The phenomenon always occurs exactly at the same speed and otherwise in no other speed range. Could it possibly be due to the tires / rims? That would be the only logical thing? But why only at this speed and neither below nor above? I currently have unfortunately not a summer bike set since so I can not mount another set test by test. VG Tom
