Hi there,

My son has just fitted a Marzocchi 55 ATA to his Santa Cruz Chameleon. It certainly looks the part but the instructions that come with it and those available on line are pants! Neither of us can work out what we should do to set them up, especially as there are so many options. We have located where to attach the pump but that is about all.
As such we pumped up to 100 to see what that would do. It feels plush but there is an initial 20mm where nothing seems to happen. i.e. immediate sag with no weight applied except the weight of the bike. The manual suggested there are two chambers to utilise but we can only see one connection.
The above looks just as confused as we are, but if anyone has any ideas it would be appreciated.

Cheers,
Phillip
