I’ve a DSW Diverge 105 with hydraulics 🙂 – as far as I can ascertain (and there’s not even any real consensus from Specialised support) the DSW frame, assuming it’s still qr, is non SCS (as noted above qr frames have a normal chainline).
However… I think that the rear wheel (Axis 4.0) on mine has an SCS hub, and uses a special hanger to ensure the chainline is correct. When I look at the hanger there’s a small offset, which I assume compensates for the 2.5mm difference in spacing.
If you want to use a normal wheel, the you need an alternate hanger (Wheels Manufacturing 146 I believe)
This is all as I understand it at the moment- I’ve new wheels on the way, so will be finding out for sure soon enough.
EDIT: I’ve just ducked out to the garage and had a look at the rear hub- it has ‘SCS 1532 N E’ printed on it- I assume from the labelling it’s an SCS hub, and what I’ve written above is likely to be correct.
