I’ve just fitted some 2017 Lyrics with standard spacing Hope Pro4 hubs, I noticed the dropout flange bit looks wider, do I need to swap out the 15mm caps for torque caps or will it be fine with the old style 15mm’s? it all snugs up ok.

You’ll be fine with the normal 15mm caps. The torque caps just make fitting the wheel a bit easier as they centre the hub in the dropout better

I’m on bog standard 15mm spacers with Pro4/Lyriks.

All works fine.

Torque caps make fitting wheel easier, do they increase stiffness, probably, but not that anyone can honestly notice!

If only there was a wider stiffer axle standard they could have used, eh?

Ha – George – yes 20mm !

Anyway Hope make torque cap spacers now.

Boost 150×40?
