Quick question: What size allen for rear axle (removing rear wheel)?

[ROJA]

This is for a 2016 Turbo X but I imagine they're all the same. Is it a 5mm?

Thanks!

Yes....

Thanks. I just ordered a tool on Amazon - I'm worried that I wouldn't be able to actually loosen the nut/axle with my regular little L-shaped allens.
