Yes im using in on the elite gel trainer

yes it is

I have an Elite Travel Trainer, originally supplied without a Quick Release. This fits just fine and has eliminated the slack where the turbo trainer joins the bike.

Yes , it fits my Elite turbo perfectly

I purchased one for the elite crono elastogel. the tacx has a square end wich doesnt fit the elite clamp. so, no it isnt in this instance although it may fit others

Absolutely,

No problem. Take it off your trainer and ride away.

Hi, I have used it on the road many times (on my road bike) and never had any problems. It's certainly durable if slightly heavier than a regular skewer.

No problem at all with using it on the road as I often do. Just make sure that the skewer is tightened up and pushed so that it falls between the two tubes of the rear triangle as I find it is much less prone to vibrate loose (I do this with all my skewers)

Length is 163mm. They dont do a longer version. Think there may be something odd about your tri bike.. is it 11 speed?

This skewer is intended for use with a turbo trainer. It is certainly longer than the one I use on the road, but fits the trainer perfectly.
