    This may seem an odd question...

    Especially coming from me :oops:. But I don't have a set of calipers for measuring inside lug dimensions.

    The 750T, I've heard referred to as 21 mm between the lugs. But I also think I remember seeing someone say it was 21.5 mm.

    Why would this matter? I've decided to try a Shark strap (sort of a Sharky on Shark thing ), and discovered that the source I will buy from has both 22 mm and 21 mm straps available. So I'm bound to decide between these two, instead of the usual 20 mm vs. 22 mm choice I normally have (I generally go 22 mm).

    I know the Hirsch Liberty, though a bit tight, looks and works fine at 22 mm, so I'm inclined to go with that. But I wondered if anyone here has actually measured theirs, and if it is in fact 21.5 mm, or 21 mm (and should I go with a 21 mm strap?).

    What says the hive mind?
    Regards, T Bone.

    T Bone ... I would give Pete a call ... I'm sure he has measured it. If you need his phone number PM or email me.

    Hi T-Bone, thanks for the question and welcome to the forum. While I don't have the exact answer, I'm sure our friends at DOXA would be extremely glad to help. They're easily accessible, via "live chat", email, or the convenient toll-free number. Let us know what you find out, and good luck with the straps.

    (sorry couldn't help it)

    T Bone,
    My dial caliper is in inches. When I place the calipers on a steel rule calibrated in mm, it is 21mm for the inner lug width. Doxa says 21mm in their specs and that's good enough for me. Hope this helps. The endlinks are such a tiny bit under 21mm that you can't even fit a human hair between the lug and link. If you want the measurement in inches it's .830 inner lug and .825 outside of end link. That's pretty close tolerances in my book. BTW for comparison my steelfish 22mm end links are .863 in and lugs are .868 or precisely .005 in difference.
    I figured I'd throw that in for those doubting Thomases out there

    Hope that helps.

    Have the #, and haven't read or heard from him in awhile (maybe he's traveling for work again?). I'll give 'im a call. Thanks John

    Thanks Joe, I appreciate the help. Interesting to know about the .005" difference on the end links too (5 mills must be just the right amount of clearance for the end links).

    Looks like it's going to be the 21mm. I'll post pics when it gets here of course.
    Regards, T Bone.

    T-Bone

    I know OttoFrei sells this handy Bergeon template of lug width sizes. And Bergeon's stuff is so highly designed that you might be able to tell the difference in a half mm. I'd go with the 21 and see if getting it wet or just the wear and tear of everyday life doesn't cause the fibers to swell. Some leathers shrink with wear, while others swell a bit. I've found with nylon//zulu fibers they all swell to a larger size once wetted with water or perspiration.


    God Bless, Liz
