Extreme Bowstrings and cables are custom built to-order. Each string and cable is computer specked then measured to the exact length and color or colors you specify. All strings and cables all pre-stretched, served and stretched again at over 300 pounds, eliminating the need for constant cam timing and synchronization. The stretching process also eliminates peep rotation and the need for a peep alignment device. You’ll find our servings to be extremely tight.

I have been shooting Extreme BowStrings for over 5 years and they perform Flawlessly in target and hunting situations.  And Perfectly made every time which helps greatly in setting up and tuning.
Put a set on your bow and see where it leads you.

Just wanted to give you an update from this weekend Ron. Received my new set of astro flight strings on Saturday, put them on and shot them in during the week. The following weekend I went to a big two day 3d tournament and took home the buckle in the men's open money class. I also won another shoot off buckle for all around grand champion. Your strings were flawless in looks and accuracy as usual. As far as I am concerned there is not a better string maker anywhere. Absolutely the best!!!
Thanks Again.
Update 6/12/2016: Hey Ron, had another great weekend shooting your strings bud, they took me to the top once again and I was able to bring home two buckles and a Thousand Dollars for the Grand Champion Shootoff!! Just wanted to say thanks again for all the awesome work you do and thanks for allowing me to help represent such a wonderful company and product!   To become a Champion, First purchase from Extreme Bowstrings, install, tune and forget, then concentrate on just shooting.

Ron, I just wanted to let you know that the Astroflight strings you made for my Shadowcat are still holding up very well! I won the BHFS flights division at Vegas this weekend. I also set a new BHFS record. I'm the first person to ever shoot a 900 with BHFS equipment in the history of the Vegas shoot!
