I've been riding steel for a while now and recently added a CAAD10 to the fleet. I am planning on taking it with me on our upcoming vacation.
I have a Thule gateeway 2 (trunk rack) that I've been transporting the steel bikes on very happily. My question is, should I be concerned carrying the lightweight aluminum frame in such a manner?
I brought the bike home from the shop initially this way and I felt that I had it secured on there without placing too much undue pressure on the frame itself. However, that was a short 5-10 mile transport.
Update: I have found it and included here. Upon re-inspection, I see that it says "not recommended" for either, but "do not use" is for CF.
"hAnGeR RACk On this type the bicycle hangs on two arms projecting aft from a trunk mounted rack: Not recommended for either carbon or aluminum bikes. Do not use on bikes with carbon fiber tubes. The point loading where the arms contact the underside of the tubes may crack the tubes. Additionally the lower part of the bike is difficult to secure, and it may move, causing chafing and structural wear. Additionally when two bikes are mounted on these racks the contact points between the bikes may be cracked or chafed, causing structural damage."
