I have just received my tacx e-thru adapter after waiting ages but it has a fine thread and doesn't seem to fit my bike. I have a Giant Deffy Advanced, do I need to get the 12x1.5? (142x12mm). On Amazon the T1710 seems to be 170, is this the correct one?

The Robert Axle Project has an axle finder that suggests that yes, you need 12 x 1.5 (they'll also sell you one).
