THULE ROUNDTRIP TRANSITION

£519.99 Bulky box but good protection

Weight 17.6kg Size 137x94x39cm Disassembly involved Wheels/skewers, bar/stem, pedals Wheels Two, fixed

The RoundTrip is a beast of a box that offers plenty of room, good protection and an internal frame mount that unclips and doubles as a work stand with the three legs provided. It’s not especially stable but makes it easier to build and tune your bike post-journey. The Thule’s downsides are that its large size can make it cumbersome to lift and manoeuvre. Weighing 17.6kg means you need to have a light bike to hit most airlines’ weight limits.
