I ordered a Giant TCR Advanced 1 (2018) and it's on its way. I just remembered that I need to get a thru axle that fits my Smart Trainer (Tacx Flow Smart. Sadly I can not seem to find the measurements on Giant's website to order the correct one from Tacx's selection.

I read that it is a 142x12mm, but there are several in that list with that measurements and sadly I don't know which of these would fit. Can anyone help me figure it out?

thanks

EDIT Looks like the 2018 version (at least mine) has a quick release (I thought it had a thru axle) and I was able to use the quick release "axle" that was provided with the Tacx Flow.

The specs of the thru-axle that you need are here. The one that you need is T1707, which is 12×142 with a thread of M12×1.

The T1707 and the T1711 both fit a 142×12 mm with a thread of M12×1. The T1707 has an axle length of 162.5 mm, while the T1711 has an axle length of 175 mm. I couldn't find the TCR specs for this online, but since I ride a Giant Propel Disc, which has the same thru-axles as a TCR, I was able to take mine out of my bike to measure it. I found that it measured 162.5 mm (see photo). This means that the T1707 is the correct axle. enter image description here

    I work at a Giant store that also sells Tacx trainers, so with any luck I'll be able to dazzle a customer with my product knowledge now that I've done the research already.

    Today I got my bike and it has a quick release (I thought it had a thru axle) so I could use the quick release "axle" that was part of the trainer.

Please be aware of the thread you have. The thread in the picture looks like medium thread, although the recommended thru-axle has fine thread.

In case you need medium thread (like me), you need the T1710.
