I am currently waiting for tuning from Bikespeed. My bike dealer has always worked with them and has had almost no problems and has always been satisfied with the quality. I have contacted Bikespeed and they are short of components to put it into production. We are talking about weeks and not months before they will be on the market.
After some research and different opinions I am not convinced by the current tuning devices on the market. Too many error messages, having an countdown, ... I hope for myself when I buy one that it works perfectly without too many problems.
For your information I have a Cube Khatmandu SL 750 with smart system. Sorry this message is in English, I'm from Belgium.
