Most bikes seem to have an Achilles Heal with shock fit options today it seems form has taken over function, I know it can't be easy with so many suppliers, are they're really that many?
Its def not unique to Turner though it does seem a Horizontal shock placement vs a vertical shock placement limits tolerances. Again no issue on the new V10
I just got a latest UK mag that states the Demo 2 has V-air fit issues, already with that bike ya need a different yoke- to shock to fit a Fox or a Rock Shox have no idea what that means for a BOS or CCDB, or the Vair, but have seen on PB a Demo 2 with a Vivid air

Oh I rate this bike too so not cracking on Spec here either!
Dave has specced his bikes with Fox for years!
But it would seem prudent to be able to run those afore mentioned!
V Air V Coil, CCDB, Elka BOS
All leading shock and Fork suppliers, anything less only limits potential frame sales and I don't get that at all.
cheezwhip ran a Vivid coil back in the day, not sure if he still runs this rig or not would like to run a Vivid R2C2 on mine, not after a V air but it would be nice to know it would fit.
