Through axle for smart trainers?

Hey guys,

I just got my first smart trainer; a Kickr Core. I heard from another rider that you should use a stronger through axle than the one that comes with your bike. Apparently the standard axle is prone to bend/break when used in conjunction with a smart trainer. If this is the case does anyone have any recommendations? Thanks in advance.

I bought an used Trek 2200 in perfect condition just for the trainer. I don’t want to mess with any potential issues in my real bike + the convenience of not be mounting and dismounting. A true game changer.

I don’t think so. A through axle plenty sturdy to cope with trainer usage. I wouldn’t worry about it.

That’s a great option if you have the space for it. There are plenty of rim brake road bikes that can be had for cheap. And you will be fine with e. g. a 10-gear drive train or so. Weight doesn’t matter either, you don’t need fancy wheels, and in principle you could even take off some parts like the brakes and the FD.
