B&W Sac de Transport Bike Bag II

Great bag, have been using it for more than a year now, travelled with it 4-5 times (8-10 flights), no issues.

Downsides I noticed:
- I found chain arrangement inside the bag is not very straight forward and not very effective, difficult to cover the whole chain and it falls out from the sleeve... not the best design.
- Wheel covers lack protection for the hubs, so they easily rubbed through the covers and the whole bag to the outside at the first use. The bike got no damage but the bag has a small hole in it now. I glued some wear resistant plastic patches (I cut them from a cheap flexible cutting board) in the centres of the wheel bags from inside and so far it works very well.

Otherwise, it provides good protection, it's lightweight, plenty of space inside to put stuff, and also due to soft top design it's easy to fit into a car or taxi, and it takes relatively little space while stored at home.
