Like most of the MTBs out there right now, my MTB is also a 29” model. Being aware of the size I did call previous to my order two online bike shops to find out if there are any restrictions using the bike case. To be fair, both couldn’t say with a certainty there wouldn’t be any problem. At the same time, none of them said they did hear any complaints from customers (which makes me wonder afterwards). I did also check the THULE product description and couldn’t find any important notes about the size. “Fits most road, mountain, and cyclocross bikes” implies to me 29” are included. I did order the bike and was looking forward to my trip. Few days before my trip I did start to pack up my bike. Everything went well till the final placement of the bike in the case (instruction video at 01:45). To my surprise I couldn’t click in the bike holder into the mount system on the bottom of the case entirely, because the length between the front and rear axis is too big to fit into the bike case (my bike is L size according to the manufacturer). I was very disappointed about this fact, since that was the main reason for me to buy this bike case, namely, the bike is fix in a box during a flight! I had already few bikes on flights and the constant vibrations can cause severe damages to bikes, especially when the frame has contact with other parts et cetera or is stored together with other shipment goods. Being aware of that I additionally used cardboard to fix the handlebar & protect the fork as well to separate the wheels (even packed in the bags). I did also tight up the chain to the frame with old shirts to avoid scratches on the frame. The “trick” was in the end to use the saddle as a stopper/blocker to the upside of the case within the case. I think, everyone who was on airplane did experience some heavy turbulences. Same happens to your bike, so I tried to avoid this with the saddle positioning. In the end my bike arrived well at the destination airport (at this point on a side note: many airlines exclude any responsibility for damages on sports equipment). No real damages on the bike inside. TL;DR I don’t recommend the bike case for 29” models, if you like your bike to be really fixed in the case.
