Theoretically, yes. However, it is possible that the cage from the changer will hit the housing. Here is the information on the Tacx page: A bicycle with a rear derailleur with a long cage will not fit on the FLUX if the maximum distance between the centre of the hub and the FLUX stand is over 200 mm (as shown in the picture below). When using a rear derailleur with a long cage, the stand will be touched in the highest gear.
