The most likely causes of excessive wobble at speed on a motorway are either that you have not placed the arm clamp sufficiently close to the chainring OR you have not tightened the clamp sufficiently. Having said that, there is a further cause where the clamp can slip UP the frame IF your frame gets thinner in that direction (eg My Cervelo S3 does precisely that). In that scenario you will need to put the arm clamp slightly further away from the chainrings at a thinner part of the frame.
I have been a long time fan of Thule racks and accessories. Then at sixty Mph my two week old Kayak departed the rack still attached to a new pair of Thule Hull-a-ports. Thule make a bomber rack system and the Hull-a-port is a great concept but why the plastic clamps?. The kayak landed safely in a snowbank but I worry about what might have happened.
We spoke to Tom Henwood of Main Line Overland to see what the pros are using and what’s popular on today’s market. “The best roof rack is the best design for a given application, rather than a particular brand. We help customers select racks and storage systems based on what they intend to carry on their travels, where they intend to go, etc. We look for componentry that maintains a low profile and low center of gravity for off-road driving, so we often choose aluminum roof racks to keep weight down up top.”

These are ideal if you are carrying kayaks or bikes and know that lifting these into the centre of the roof will put a strain on your back. They're almost essential for safe loading on tall and / or wide vehicles. The bars slide out so you can load, for example, two bikes on the left side of your vehicle, then slide them the other way and load two more on the right. They're brilliant.
