We just bought an
Orucase for our trip to Tahiti next year, and maybe for Spain this year but that is only 7 days so getting in saddle time is probably going to be a no go. It takes roughly 20-30 minutes assembly time, but for me portability while traveling is hands down the most important. There's nothing worse than being rushed in a train station or taxi stand and not being able to manage all your luggage.
I ride a 50cm SuperSix, so it can hopefully slip past the fees.
