The OEM space is interesting these days.
RS/SRAM have a lot bagged
Fox/RF/Easton Packages a lot
As said I just can’t see Shimano/Marzocchi existing in the same space, just too different in brand/style.
DVO are hitting a nice space in exclusive/limited offer what they want in the space you want. If you want a good OEM deal then you need to cover XC to DH well. Marz are covering but not sure how well, without the backing of a big owner/parent to come through when things go lean or to undercut Fox by the amount RS did with the Pike deals that were going round.
It might be best to go for the specialist market but they would have to cut a lot and prices would rise (BOS/DVO/Cane Creek)
Throwing in the return of Manitou and the value that X-Fusion/Suntour offer with decent quality it’s not a good space to be working in and as it appears stuck in the middle.
