Packing bike bags can be a chore, yet cutting corners could prove costly. The Anti-Shock bike bag frame, exclusive to Geoffrey Butler Cycles, looks a touch ‘Heath Robinson’ but it’s effective and a real labour saver.

It’s a sturdy steel framework, adjustable for different bikes, on a cloth-covered plywood base (80x19cm). Setting it up initially can be fiddly, and it’s easier with a helper. The forks and rear dropouts simply slot onto axles, protecting against crushing, and also keeping the chainrings up out of harm’s way.

The bike is secured with standard quick-release skewers, supplied, so it couldn’t be simpler. There’s no need to remove the rear mech, as there’s a separate protector, saving time and hassle.

Just turn the bars under, bubble wrap then put the whole thing in your bag.
