Hi! Is there anyone who's kind enough to measure the perpendicular distance from the rotor mounting surface to the non-drive side axle end surface (the flat end that sticks to the flat inner side of the non-drive side dropout of the frame) of their Tune MTB Disc QR front and rear hubs? I am trying to get a spare wheel with Tune hubs, but I'm not sure I want to spend a huge amount again on their most expensive hubs just to be able to change wheels without adjusting the calipers during a race. My other wheels have Extralite hubs and the Hyperhubs have a longer distance compared to the Ultrahubs SPD. I'm not sure I want the idea putting shims on WW wheels that I spent a fortune for. So I am buying another wheelset with Hyperhubs, and am wondering if I need to do the same with my Tune wheels.

I need measurements for these:

King:
Princess:
Princess Skyline:

Kong:
Prince:
Dezibel:

I will measure my hubs tonight when I get home.

Thanks!

Front Princess: 12mm
Rear Prince: 21mm

Taken with plastic calipers, so I couldn't measure tenths of a mm, but these numbers look spot-on.

Great! Thanks a lot! I'm measuring mine with a plastic caliper too. It's the only one I have.

Also I believe mine are "Skyline" because they have 15mm axles, not the new 17mm. But I don't think the axle increase would change these specs.

EDIT 11/17: Just saw photos of the Skyline series hubs today, to confirm model differences.
Very impressive, similar to the Prince/Princess series with carbon flange edges, and NDS flangeless design.

I think the Skylines have radial drive side spoke orientation and that radial drillings on the hubs have carbon reinforcement.

Here's what I got with a plastic caliper,

Princess Skyline = 11mm
Dezibel = 15.5mm

I'll borrow a more accurate digital caliper from work and measure again later.

With a digital caliper, I got:

Princes Skyline = 10.6mm

Dezibel = 15.6

Anybody else who measured their Tune hubs?

FWIW, if you need less of that distance, rotor spacers can be made very thin, and don't affect brake performance.
OTOH, if you need more distance from the NDS dropout, then maybe a friend with a milling machine (only part joke)
