Proceed with xtreme caution
Four friends did RAGBRAI last summer and paid to have their bikes packed by a LBS in Iowa, at the end, and shipped home via UPS. They paid for insurance. When the bikes arrived in San Francisco, ALL of them had signifigant damage, two beyond repair. UPS has been no help whatsoever. The insurance that they paid for appears to be useless.
If I were shipping my bike, I'd buy a case, and I wouldn't use UPS.
Rent the case and ship it back..
Couldn't you just rent the hard case and ship it back empty to the bike shop?
