Many bowstring builders have found themselves in a little bit of a bad situation with the recent discontinuing of the BCY X bow string material. They have to ask themselves whether to keep buying the X material or to start their inventory all over with the new X99 material that is replacing the X. The good news is that 60X Custom Bow Strings bought up a large volume of the X material to keep our customers in stock. The bad news is that once the material is gone, it is gone. We try to keep our website up to date with what’s left in 1/8lb and 1/4lb spools. The bulk 1lb spools are hit and miss at this time. Most popular colors are gone in the bulk spools but feel free to contact us. We still have a large amount in our personal inventory that we are willing to sell as well. As time goes on we will be adding more of the new X99 bowstring material to our inventory.
