Unfortunately, it looks like the Isozone grips/bars make it impossible to install both bar ends and a bar end mirror on Trek FX bikes. The Isozone Satellite Plus bar end adapter has a plug that fits in the end of the handlebar that leaves no room for the bar end mirror. This is disappointing as I have tried other mirrors over the years and really like the bar end ones like the Mirrycle bar end mirror.
