Mission Sub1 XR Tuning

I noticed that the strings and cables are served all the way to the cams. How do you time or sync the cams?

I twisted the unserved portion. Was able to get two twists but tedious trying to get hooked up again. Just make sure you are twisting with the twists in the serving, unless you wont to reduce weight.
Thanks for the reply. Monday I emailed Mission the above question. The tech responded back that both the string as well as the cables are served 100% to the specific length needed to keep the xbow in tune when replaced!!
When I replace the string and cables Ill definitely make measurements and mark the cams for reference!!
Ok, showing how new I am to xbows... I was under the impression there was no tuning a Sub-1..?
From a rookie... what is “tuning a crossbow? “ Also own a sub 1 xr

Would be nice to know as I was told no tuning required for a Sub1 as well..?
There’s no such things a s a bow ( crossbow or vertical ) that can’t be tuned. That being said, the design of the Sub series of crossbows makes them much less critical of tune and still very accurate even if they are slightly out of tune. To achieve maximum accuracy, forgiveness, and speed though they still need to be perfectly tuned.
Tournament season is almost here and I have another new Sub on its way so I will be busy tuning all of mine very soon.
Any interest in a maybe a video ?

That’s an offer I can’t refuse! Would be very much appreciated! Thanks

Indeed, that would be of great help and most appreciated THA!
Cheers from WTZ!

I would also be interested, as a potential future Sub-1 XR buyer!
I bought a mint used Sub-1 XR last Saturday, and these are the weirdest cable loops to cam pegs I’ve ever seen. The string and cables are served 100% except for the loop eyes.

ATA uncocked is 12 1/2” and mine looks to be right at 12 9/16”. I could probably unhook a loop on each side and figure out which direction to add a 1/2 twist on each cable to pull that ATA to spec.

But I think I’ll wait until I’ve shot it more before making any changes.

As a side note, what's your opinion on the bow?

Well, it’s a bit heavier than my Dagger but still balances well with the swept back past parallel limbs. String and cable attachments are a bit confusing (I’d like to see a routing diagram to follow if I replace anything), the shaft retainer is rather slick, trigger is smooth and quick, and it seems rather quiet overall and vibration free. I do like the adjustable comb on the stock.

I mounted my Zeiss XB75 on it and I’m anxious to see how it groups indexed shafts at distances. Seriously thinking about getting another Ravin Jack Plat and use my extra Vortex Venom red dot with it.

Will probably sell the Dagger (brother-in-law wants it) and might even sell my silver Ventilator - I don’t need 4 crossbows. :confused:

I did get the Vendetta I rangefinder mounted and I’ll align it once the scope is sighted in.

I got (6) Mission bolts with it but at 345gr with 100gr inserts, they're are a tad lightweight. My first check put the FOC at about 12% which I thought was odd for a short 19” shaft.

Nice
Any chance of getting the video put together and uploaded to the site here?
I would be very interested in seeing the video also. Thanks in advance for doing it.
I too would be very interested in a tuning video.

I can only speak from my string and cable B.O.S. install experience with my 60X S/C and their served loops. Their bowstring has a 1 plus inch area that's not served. Per Farm Deer's recommendation I put one twist in the bow string (each side). Nothing to do with the fully served cables. No timing is required. Works as advertised. Just loosen the B.O.S. out enough (XR model) to remove the cable and strings. For me, my 60X strings I backed out the B.O.S. bolts 14 turns. Install the S/C and tighten completely till the B.O.S. bolts stops and limbs are tightly secured to the riser. That's the beauty of Mission's cam design. Syncing cams not required. At least that was my experience.

I have a video posted in the Mission forum. Good luck!

Please someone put a video out on string set change & cam tuning on a sub1!
And no it isn't neither uncomplicated or easy for those of us who haven't done it.
Many thanks in advance!

Thanks TOTR! To the contrary I read a posting from tryinhardarcher that all cams including Mission xbows can be and do require timing for the best performance/accuracy.
Just saying...
