No ATAC models control the front arm shock and previous M ATAC came with the IFP front arm shock off the base models. This the first time the M ATAC models come with the QS3 float on the front arm. I was not impressed when my 2021 showed up with the cheap IFP shock on the front arm. And non ATAC models had 4 QS3 on them.Also was not aware the front track shock was not ATAC. Might be ok, not sure it’s good running that shock in anything less then medium. Have never tried that shock on hard; maybe only for jumpers?
