Sizing for 29er Mountain bikes (hardtail & Full Suspension)
Small / Medium / Large Hardtail 29ers use the 2X Oversized standard case. But verify dimensions...

29er cases require the additional purchase of 29er sized wheelbags..
Road Bike Sizing Up to 54cm purchase a standard sized case. For 56-58 purchase the oversized, 60 and larger purchase the 2X oversized versions, offer much more room.

You add (in inches) the length, plus the width, plus the height of the object which together equals 62 LINEAR inches.
you can take any numbers that total 62 inches but doesn't exceed that for luggage guidelines.
X linear inches = length + width + depth (measured in inches).
It will be very hard to package a complete bike in a travel case, no matter the case and have it come in under 62 linear inches, be prepared to pay for your bike and just enjoy your trip with a Delta Cases bike case.
