So far so good. I did not die due to this chinese frame nor was there any kind of technical failure (yet)
To be honest, I can only compare it to my Votec VRC Pro and the TanTan is sooooo much more agile, direct and fast. In direct comparison with the Votec you don't need any effort to get it going. However, this was just the first impression and the weather in Germany is not yet ideal for longer rides. But I'll keep you posted

Are you living near cologne by any chance? Would love to see the x68 in person, before pulling the trigger
