STE synchrometer - SK or BK

[Fanalone]

Hi all


I`m looking at buying the STE synchrometer, but are not able to figure out if I need to buy the STE SK or BK version.
I have asked a supplier, and they responds BK, but when I reed tech. data on BK, it is intended for +50mm diameter!
While the SK is intended for 39 - 54 mm.
But then there is also a couple of adaptors for the DCNF, no.13 & no.41, and I suspect they are intended for the BK version
So multiple choices, and I have checked several suppliers, bout German & UK, but still not clear to me.
I have also downloaded the STE manual, which makes it even more confusing

I just don`t want to order the wrong tool, returning procedures are time & $$$ consuming!

Any experience here?

I have one, but not at hand. I probably won’t be able to check until next weekend.

I have a pair of SK and they fit and work well on the 40 DCNF.
