Every bow requires limbs, most beginner, and some intermediate bow kits come with limbs. If an archer moves towards competition archery, they will want to upgrade this essential element. Designers of limbs strive for an ideal combination of speed, stability and smoothness when deciding what materials to use and how to combine them.
Modern recurve limbs are made from multiple layers including fiberglass, carbon and/or wood and usually are laminated over a core of wood or carbon foam. A good archer will be able to shoot well with any good set of limbs, no matter the composition and elite archers often have a selection of various types for different training purposes, they usually gravitate towards one.
Foam-core limbs are more resistant to warping, are usually lighter and are not affected by humidity and/or weather conditions. They provide a consistent straight smooth pull curve and a faster shot. Carbon foam-core limbs are usually a lot more expensive and require a lot care. Archers need to inspect and repair even minor imperfections as they can lead to massive failure. Whereas, Wood-Core Limbs are usually far less expensive than foam-core, and are usually more durable. Although they usually have, a little more mass weight they can deliver a slightly higher speed with the same poundage as foam-core limbs.
Manufacturers produce limbs in various strengths or draw weights to service all types of archers and are measured in poundage (#) at a certain draw length (usually twenty-eight inches) and by length of risers.
Example is 66”-34# @ 28” or 68”- 32#@28”
Since not all archers have the same draw length, the same limbs will be different for each archer. The same set of 34# limbs for an archer with a 24” draw length will pull less than 34# and an archer with a greater than 28” draw will pull more than 34#. You can easily determine your draw weight using a bowscale at your local archery shop.
Limbs also come in various lengths that will determine the overall length of the bow which may be a factor for shorter archers. This chart can help you determine which length to order.
|Riser Size||Long Limbs||Medium Limbs||Short Limbs|
Limbs use to be designed specifically for the manufacturers riser and once you purchased a riser you were bound to that manufacturer for limbs or you would have to change both limbs and riser. Now most manufacturers use International Limb Fittings or ILF and are an unofficial standard that allow limbs manufactured by different companies to fit on the various risers.
There are several great manufacturers of limbs and in 2010 MK Archery started producing a great set of competition limbs. Currently holding world records in recurve men with scores of 1386 for FITA and 342 for 90M. The two top of the line models are the MK 1440 (foam-core) and VERA (wood-core). The limbs are made from multiple crossed carbon layers, laminated over a foam or wood core. If you are seriously considering investing in a good set of limbs, consider some from MK Archery.
