Magura MT7 caliper dimensions ? (for fitting to hub motor)

Trying to figure out if they would fit with a Mxus 3k, if anybody has them - it would help if you could measure this dimension:



(as mentioned already in this post but without answer https://endless-sphere.com/forums/viewtopic.php?f=31&t=79942&p=1179048&hilit=mt7e#p1193094)

It's aprox 17 mm . You'll need 2.5-3 mm spacer under the disc. On a FUTR Beta frame it's way too tight to fit.

Thanks. I bought them. It's around 16.2mm in my case, so one needs a tiny bit more clearance than than.

I did manage squeeze this in with Mxus and standard MBT 135mm dropout. Great brakes. Can lock out rear wheel with mxus.
