Hello, yesterday my gas train is unfortunately torn (opener) – the original costs 27€, at Louis there are Nipple Bowden train sets for 4,99€.https://www.louis.de/article/nippel-bowden train set/10019100 Do these have any disadvantages compared to the original Bowden train sets? Did simply consider to install the cheap Louis kit instead of having the original delivered to me.. or are these only suitable for short phases? mfG, Tim
