I got some – look well made and a **** load cheaper than anything else around. I nearly bought some off ebay for £49 – have seen them for £80 on ebay too.
But..
1. the clamp is a bit high for my car – not a huge problem as they are universal. At least it does fit snuggly.
2. I don’t like the end caps which just push on. I prefer the Thule ones that lock or get gripped by the clamp as it’s another barrier against removing racks.
3. I went to fit my Thule bike racks using the T track fittings and the bloody slots are too narrow so I would need new slimmer T bolts.
4. So I thought I’ll use the alternative fittings but as they are aero style bars they are too wide for the steel square bar fittings that come on one of my racks (U bolt). They may work with the curved ones on the 591 racks but I didn’t get that far.
arse! at £27 they are a really good deal if you can use them with your racks.
