Taking a mtb on a plane

I did in one direction but couldn't be arsed in the other. They were fine. Alaska Air to BC for reference.

edit to say I'd still take them off on the way to a biking vacation, though, just avoid having issues at the start.

I do. But in the past, I didn’t, and that worked ok too. If I don’t, then I pad out the wheel, beside the rotor, to make sure nothing can push in, and bend the rotor.

I do on my road bike, mostly cos the way the wheels stack in the lid of the bike box puts one rotor rim right up against the tyre of the other wheel.

Plus they're CentreLock so it's only about 30 seconds to remove and refit a rotor.

I think a different box design where the wheels were in their own bag or something, there'd be no need for removal.

I haven't taken my rotors off in maybe 30 flights, never had an issue. I do pack the wheels rotor-in, I can't see how anything would damage them without taking out half the bike

I do.

Never taken them off. Never had a problem.

We've never taken them off transporting in evoc bags ( one pro one normal) with no issues

I've always taken them off.  Couple of minutes effort, why not.

My bag says to leave them on and has some padding/protection for them (Evoc pro). However, summer trip to Morzine 2 years ago, disc was pretty mangled when we got there and had to borrow a spare.

I take them off now. Or do on the way out, risk it way back if I’m being lazy.

Never taken them off on multiple trips, never had a problem. Bike travels inside a VeloVault2.

(Although I managed to Pringle one of them by knocking the bike over in the hotel room).

Yes, doesn't add much time to build. It would take a hellavu bump to bend it in an evoc bag but better safe and all that.

Evoc bag and always take them off.

Cardboard box n left em on but had the disc inwards n clothing around the rear. I did take the rear derailleur off though.

Mods please change thread title to 'Brakes on a Plane'

Evoc Pro. Supposed to be ok without taking off. 6th flight both discs bent enough to be v annoying. I will now take them off 100% on the way out. No promises on return
