The Thule RoudTrip Pro 100501 does a good job for a soft bike bag, but it isn't fully protecting your bike...
This is a soft shell bike case with a difference — its clever, dual- purpose design means it can double as a workstand.
The base, which holds the bike static in the case, can have three legs added, transforming it into a workstand for when you get to your destination.
As a flight bag the base does a good job of holding the bike securely so that when it’s combined with the rigid tub everything is safely stowed. The sides of the bag are reinforced with plastic panels that can be removed to improve access. However, half an hour in the sun saw the panels expand making them almost impossible to get back in — less than handy if you’re rushing to catch a flight.
The handlebars have to be removed, although the stem can remain in place, albeit a little exposed at the front of the bag where there is little in the way of protection. The same is also true for the top of the seat tube and the rear triangle — removal of the rear mech and hanger is a must.
The RoundTrip is certainly better than a simple soft bag, but still has some fundamental weak spots, which will leave you worrying as you wave goodbye to your steed at the baggage drop. For a fiver short of £500, we’d expect total peace of mind.
