well tomorrow my hard rock is going into the box and comes with me to europe for the next 3 month .
is there anything i should do to the bike like maybe tightening the spokes so they don't get bended?
i was just gonna take the wheels ,pedals,seatpost,rear derailler and disc off.
any suggestions are welcome since i never had to box a bike before.

well i woudnt suggest tightening your spokes becaus then you would have to get the retensioned. wheels pedals and seatpost could come off but the disk and derailur i wouldnt think need to. just use bubble wrap to protect everything(and lots of fragile stickers)

About a month ago I sent my bike across the country. I just took my handlebars, front tire, and pedals off. I got a box from an lbs for free. It shipped pretty well, although I should've used some sort of padding because there were holes where the bike touched the box. I shipped with DHL because they were the least expensive. I found cross country shipping to be rather hassle-free, but I am not sure about overseas. Are you shipping it by mail, or taking it on the plane for you?

yeah i am taking it on the plane but i figured more people here have send a bike rather than took it on plane ,but it should be the same .
i got the box and i try too throw a lot of bubblewrap in there .i am kinda afraid about the rear derailler so i will probably just take it of .
with the spokes you are correct ,i would have to re adjust but the wheels are allready not true right now so i have to true it out anyways .
thx guys.

Honestly SHIP the bike. The TSA has a NASTY habit of screwing up bikes. My girlfriend's brother lost a carbon Trek due to damage caused by those jerkoffs. The liability clain is STILL in the pipeline and chances are he won't get full replacement value for it. The frame was gouged, the fork was actually BROKEN, the handlebars were cracked and most of the components were scratched all to hell. I will never trust those yardapes with any of my bikes as his isn't the only bike I've heard of being ruined by wannabe G-men
You'd be MUCH better off shipping it using DHL or UPS

well that would cost me like 150 $.the airline brings it for free .i guess you get what you pay for .
if its broken i still got the 150 $ to replace stuff
it might not all be a great idea to bring it with me but i need to ride and already planned trips to the mountains.i just don't want to ride my old bike at home anymore ,actually ever again.

WOW, what airline are you using that will take it for free? Most charge about $80 each way.

well its an international flight with united (lufthansa).you can bring 2 bags each 64 pounds and they don't care if you bring only one bag and a bike .
on the way back i will be using a spanish airline and they have the same deal on international flights .

That's pretty cool. It's pretty bad that you can take a bike across the ocean for free but they charge you when you fly to the next state.

if you have a couple old hubs, stick them into the dropouts to keep your fork and rear triangle from being crushed. Or go to a bikeshop and get some plastic dummies that do the same thing- every new bike comes in a box with those things- very handy to have a couple on hand. Pipe insulation comes cheap from the hardware store and can protect your tubes from scratches and dents. Remove your rear derailleur from the frame (no need to remove the cable), wrap it in cardboard or bubble wrap and duct tape it to the chainstay to keep it from being bent. Don't be tempted to ship other hard items with it, anything rattling around in the box will damage the bike, although you can stuff some clothing in there for padding and cut down on your other luggage weight. Good luck- airport security can be brutal, be prepared to take it all out and repack at the airport. If you're afraid of the weight limit, curbside check-in can work wonders. The skycaps generally are much easier to deal with than the check-in people, especially if you give them a nice tip to help you out.

I absolutely love travelling by Lufthansa. Great flight, fast, usually no delays and well, overall nice.

yes they are the best ,but you pay for it !!!
