they are tst2 not ata 2. ata forks have silvel nickel coated stanchions and are just ata not ata2... or so I beleive anyway, double check mate. I may be wrong lol
just looked on chainreaction and the 2009 55 does come in an ata model with black stanchions, it is the model is 55 ata but it also has the tst2 adjustment so im guessing thats where the 2 comes from on ata2. So maybe your right and im wrong after all lol.. If the travel adjusts then it is ata anyway no argument about it. Either way, nice looking fork and very nice bike.
