60X Custom Strings Now Installs Speed Nocks and TPU’s

With so many differences of opinion regarding the importance of nocks and TPU’s, we thought it’d be a good idea to explain the contrasts between these two types of weighted accessories. Some archers feel like speed beads are an absolute necessity, while others feel like the added weight may not be worth the installation. Once you’ve understood the benefits and drawbacks of these setups, you can determine which material works best for your shooting.

Speed Nocks - Most commonly a group of brass “nocks” or “nock-sets” crimped onto a bowstring in specific locations to achieve better performance. There are many different styles of nocks these days but they all have the same objective. That objective is adding weight on the bowstring in specific areas to create the perfect reaction of the string once the arrow is fired. From testing we have done in the past, we have seen an increase of up to 14fps with the installation of speed nocks. On the other hand, we have tested bows that did not see any benefit to nocks being installed. The other benefit we have seen is certain bows will not paper tune correctly without the installation of speed nocks (this is a very small percentage of bows).

Bow String TPU’s - An alternative to nocks that are made of a durable rubber. They do the same thing as traditional speed nocks but thread onto the string instead of being crimped on. The plus side of the bow string TPU is that with it’s rubber construction they also have string dampening and silencing properties. The downside is they weigh more than a speed nock. This means they are not quite as customizable when it comes to putting an exact amount of weight in a certain spot on the bowstring. This is only a small issue on a very low percentage of bows.

Do today’s bows need speed nocks to shoot well? The answer is no, but in most cases they will increase performance. While we no longer pre-install these add-ons on our strings, we are available to answer any questions you have about nocks, bow string TPU’s or any other bowstring related issue.
