Issuue with lenght of Trainer axle M12x1.75 for E-Thru T1708 with TACX flow

Hello I can install my bike with

- Trainer axle M12x1.75 for E-Thru T1708

- on a TACX smart flow trainer

=> i blocked during the installation of the bike on the support of the TACX as the lenght (200mm) is too long for the support.

Is it compatible?
