I have the shimano a 520 on my caad 8 and like them . They are are lighter than the a 530 but the 530 has one side platform and the 520 does not . Good looking chrome pedals . I could not post the url but nashbar has the 530 for 34 bucks and the 520 for about 44 . Make sure to set the lowest tension and leave it there for the clips . I fell over twice learning to use mine . Pedaling difference is worth it to go spd regardless .
