They all use the same mechanism, the xt tourer pedals were Allen key only fitment and were a pain to get out (rounded one off packing in budapest) so just went for the 520 cheap option for fixed as they can be fitted with a pedal spanner. Read up all about them and basically the 520s have the same bearings as the 530s, they seem fine and come in. 3 colours.
