There is no doubt that the center serving on your bow string is one of the most important pieces of your equipment. With so many bow string serving options out there it can be mind boggling when it comes to making a decision on what would be best for your application. With prices ranging from $7 to $35 a spool we are often asked if the higher price is worth any added performance or durability. As a commercial bow string builder we are always searching for the best available materials. When BCY released its powergrip bow string serving we were eager to put it to the test.

There are several characteristics that we look for in a center serving material. First off we want a bow string serving that is going to grip well and stay together with no separation. If you’ve ever had a center serving separate under the D loop you know how frustrating this can be. Next the center serving needs to be durable. We’ve seen several types start out nice and round only to wear and flatten out leading to your groups opening up and ultimately a reserve. Lastly colors would sure be nice. I could never understand why center servings were never available in colors to match the rest of the bow string and servings.

When our sample of powergrip bow string serving arrived the first thing we noticed was how tight it was braided. It wouldn’t stretch and compress like other braided serving materials. There also appears to be some type of coating on the serving. This will surely help it to grip better and improve durability. Once we found out that colors were available we were even more excited to put the powergrip serving to the test.

With our strings we’ve always found .021 center serving to give the best nock fit so that was the size we started with. We quickly found that our center servings were too thick. After measuring the material we’ve found that it runs about .002 thicker then the listed diameter. Between this and the fact that it does not compress as much when served we were getting larger than desired finished diameters. We were able to get some .018. It also measured a bit thicker but yields the finished diameter we are looking for. Keep this in mind when ordering this serving material.

The more we used the powergrip serving the more we liked the serving material. Powergrip has proven to be very durable and it holds it’s shape unlike some other serving materials. We have also noticed a dramatic decrease in center serving warranty claims. Most warranty centers were very minor compared to other serving materials we have used in the past. Our customers are loving the colors. With powergrip being available in 8 colors including black, white, red, blue, pink, flo orange, flo green and tan we are now able to use a colored center serving without sacrificing quality or durability. I think BCY has hit a homerun with their new power grip serving. Give it a shot on your next bow string. I think you will be happy with the result.
