Hello Rolleristi (nnen), my biggest child brought her little Chinese (Znen Grace =Motowell Elenor50) to wintering and my short test drive showed me besides a few small things a really fiercely racing steering head camp… I didn’t have that in my hand yet … really dangerous. The camp costs as original part 13 euros and there is a lot of equally looking goods for less money, then again consists of the same balls and comparable material. Our consideration is now to use below a bearing of a better quality: – Either again the ball variant in durable and better material (instead of 4mm possibly conversion to 6mm balls?) – or lower bearing as cone roller bearing. Of course, variant two would be better for me… Now there are tons of Chinese mass goods here in the forum and I wanted to ask if you have already installed a qualitatively better bearing below. Found a storage set for the 125er/150er Chinese, see Fo to No. 3, which I will probably try. Otherwise I would measure everything and buy a warehouse individually, there is a lot… Greeting and thanks Tina
