I have those 2 cheap ones I can let you have for any little trinkets you want shot off +postage - I need little bits for miniKens build. ....but really if you don't have anything, postage alone will do.
the main reason I don't like them it the time they take to fit, otherwise they are ok.
The ones I bought to replace them are the Halfords Advanced ones - lockable and quick fit to roofbars.... only £75 for 2 at the moment.
Hi Ken I'll let you know, thinking about it Ill use it a fair bit so will get a good one, so gonna research a bit further, If my procrastination leads me to no rack before we go to Dalby I'll give you a shout
