String Construction

There are 2 types of string construction: continuous loop and flemish twist.

Continuous loop string construction

Continuous loop (also known as an endless loop) is a single strand of string material wrapped around in a loop to set the length of the string and continues for the desired number of strands. So to make a 14 strand string, 7 complete loops are formed. When they come together, they form a 14 strand bundle. This is what we recommend for the majority of strings.

Flemish twist string construction

Flemish twist strings are composed of a number of individual lengths of material of tapering lengths. 2 bundles are formed and they are twisted together. This twisting construction forms the end loop, so no end serving is used for a flemish twist string. Because of the construction method, flemish strings are stretchier than their continuous loop counterparts. This is an excellent choice for traditional shooters or those shooting vintage bows that may not have reinforced limb tips. Extra padding is sometimes added to the end loops.

String Materials

There are many string materials out there. To help sift through that information, here's what we recommended as a good starting point for various setups:

  • Olympic Recurve: 8125 or 652 Spectra continuous loop

  • Barebow Recurve: 8125 or 652 Spectra continuous loop

  • Traditional Recurve: 652 Spectra or B55 continuous loop

  • Longbow: 8125 or 652 Spectra continuous loop

  • Vintage bows without reinforced limb tips: B55 continuous loop or flemish twist (possibly with padded loops)

BCY 8125 bow string material

8125

8125 has been the most popular material for Olympic Recurve and Barebow shooters for many years. It is the choice of many top shooters. 

Manufacturer: BCY

Fiber: SK75 Dyneema®

Bloodline Glory Pro bow string material

Glory Pro

Glory Pro is specifically designed for recurve bows to optimize both stretch and arrow speed. It features their proprietary coating so it doesn't require waxing.

Manufacturer: Bloodline

Fiber: SK75 Dyneema® + Proprietary coating

BCY 652 bow string material

652 Spectra

652 Spectra has a bit more elasticity to it than 8125 so it can have a softer feel. It is still preferred by many Korean Olympic Recurve archers.

Manufacturer: BCY

Fiber: Spectra 1000 (Same as Fast Flight™)

BCY D97 bow string material

D97

D97 is the same material as 8125, but is just thicker. It is popular for flemish twist strings.
 

Manufacturer: BCY

Fiber: SK75 Dyneema®

BCY B55 bow string material

B55

B55 has more stretch than any other string material. Some traditional archers prefer it for flemish twist strings and/or vintage bows without reinforced limb tips.

Manufacturer: BCY

Fiber: 100% Dacron polyester Dacron

Angel ASB Majesty Pro bow string material

ASB Majesty Pro

Angel's ASB Majesty Pro material features a thermally bonded resin wax. As a result of this coating, the string does not need to be waxed like other bow string materials. This is the Angel material that is most comparable to BCY's 8125.

Manufacturer: Angel

Fiber: Izanas® SK71 + Thermally bonded resin wax

Angel ASB Majesty bow string material

ASB Majesty

Angel's ASB Majesty material features the same thermally bonded resin wax as the Pro version. This material will produce a slightly softer feel and a slightly lower arrow speed than the Pro.

 

Manufacturer: Angel

Fiber: Izanas® SK71 + Thermally bonded resin wax

BCY Mercury bow string material

Mercury

Mercury has become more popular amongst compound shooters recently. It is very stiff and may be unsafe for recurve bows.

Manufacturer: BCY

Fiber: 100% SK70 Dyneema®

End Serving Materials

Our standard end serving materials are BCY 2X or .008 Spectra because they conform to curves very well and is resistant to separating. 2X also comes in a variety of colors. Premium servings include BCY Halo, BCY Powergrip, BCY 62XS, Bloodline BOA, and Bloodline ICE2.

 

Here's what we recommend based on your priorities:

  • Want a softer end serving feel - BCY 2X in black

  • Want the end serving to match the string material color - BCY 2X or Halo in color

  • Want the string material to show through the serving - BCY transparent Halo

  • Durability is the main concern - BCY Powergrip or 62XS

End Serving Materials

Center Serving Materials

BCY Halo serving material

BCY Halo

Many center servings are done with BCY Halo in black as this has proven to be an excellent center serving material for recurve and longbows. It is slick for a clean release and provides a consistent nock fit.

Angel ASB Majesty

This serving is a very durable blend of HMPE and polyester. Practically the only way to destroy it is to cut it, so do be careful when tying in or cutting off the nock set. It is an excellent material for Olympic Recurve centers servings as its slickness provides a clean release, does not show wear, and produces a consistent nock fit.

BCY Powergrip serving material

BCY Powergrip

For those barebow shooters who are string walking as their aiming method, we recommend BCY Powergrip. It has grip from its resin coating and provides more grip to be able to hold a crawl without slipping.
