I have the older qs on my track bike
With the new changes had to get it for my other bike . Very cool new functions
Takes a little time to readjust the shift lever
But up and running in no time
Worth the money and way easier installation
Than other brands I looked at
Easy to fit, plug & play. I'm not very tech savvy so I asked Paul for help with connecting to my shifter via the app & he was awesome. Very thorough & easy to understand, completed the pairing process & uploaded my settings. Went for a 5 hour test ride, beautiful smooth shifting. I should have bought this a long time ago, very happy with my purchase, thanks Paul.
