The last two with a small Shiv…I travel with it about 1 or 2 times a mo. (Tri, mtb, rr bike ) works like champ. Take the wheels off, remove the handle bars and you are set.
Friend of mine has a 56cm Shiv. He bought the bikebox by allan. It’s a thing of beauty, little extra money but it packs beautifully and transports fairly small. When you order the bike box they do a couple of custom mods to it to make it fit better.
