When shopping for a road bike travel case, you should be looking for a product with a balance of a few key aspects: bike protection, bike compatibility, ease of packing, and the overall traveling experience. First and foremost, you want your bike to arrive in unscathed, in one piece, so your vacation and your prized possession aren't ruined entirely. Bike protection is of the utmost importance, and you should consider a case that adequately protects the most vulnerable areas of your bike: the handlebars, wheels, and rear triangle. Another thing to consider is whether the case is compatible with your bike - frame size and design, handlebar size/style, and cable routing can all impact a bike travel case's compatibility with your bike. Lastly, consider the overall traveling experience with the bike travel case that you have found. Some travel cases may be very protective or extremely easy to pack, but real-world feedback from customers may highlight that excess baggage fees (overweight/oversized fees) are always charged, leading to hundreds of dollars of unforeseen travel expenses from a single flight. Finding a travel case that offers a blend of these features - protective, easy-to-travel with, lightweight, compatible with your bike - will help to ensure that traveling with your bike goes as smoothly as possible!
