I feel more safe when use this bag instead to use any car rack for my expensive bike.
This bag can save your car interior and the bike on transportation.
You have to remove the bike wheels and that's it.
No need for use any tool to remove handlebar and saddle too.
Just place the bike into the bag zip it and that's all.
I also bought the Scicon set for brake lever and gear protector to maximize my peace of mind.
I recommend off course this bag for this purpose, and not for flight cargo or anything else if you have to left the bike to anyone.
Is very small when you don't use it.
You just pack it and use the bag comes with.
Very good quality.
For flight cargo purpose you have to check the Ameritech Evolution from Scicon.
