yeah that image you posted seems to be just the clip bit.
This is the pack with the other bits at a nice gaspy price

If you have 6mm seat post QR clip, you wont need it so this pack may be right for you

So you'd need both?
Just thinking it's a pain getting the bike up and down steps so a locking rear would be useful. The Ti one is the same price as the retro kit...
... although I'm guessing as it's an old model it would need the retro kit and the frame clip?
