Hi all could anybody tell me if or where i can purchase the thule 510 bike carrier, i already have 3 but require a 4th but can't find one anywhere.

 any help gladly appreciated, Mark.

Try Thule Stuff

Ask for Chris (mention Mac Attack  and you should get a discount!)

I've spoken to them and the 510 was discontinued 4 years ago, replaced by the 591

£72.00 on wiggle

£68.00 if you ring Chris on 01274 680744

Delivered.

I have the 591s, they can be problematic for certain full-suss bikes, eg my mate's Whyte 46 wouldn't fit. Great carriers if your bikes fit though mine being: Dale Prophet and various hardtails.
