Yo-yo string is usually made of 3 materials (either a single material or a blend):
- Cotton – Traditional Yo-Yo Strings
- Polyester: Longer lasting than Cotton. Most popular material among yo-yo players.
- Nylon: Longer lasting and stiffer than Polyester. A little tough on the finger.
100% Cotton is basic yo-yo string. It has been used forever, and is still preferred by many players.
Slick is a blend of 50% Cotton and 50% Polyester or Nylon. Slick is a bit heavier than 100% Cotton and is more durable.
100% Polyester string is a bit heavier and a bit more flexible than Slick. It is more durable and both Slick and Cotton. Colors are brighter than cotton.
100% Nylon is slightly stiffer than Polyester and is more durable. It really flows through the air. So for slack, whip, or suicide tricks the loops created stay open and move fast.
Yo-yo string also comes in different thicknesses. The Type is determined by the number of threads used to create the string. Our Types Include:
- Type 6 - Thin
- Type 7-8 – Your standard weight
- Type 8-9 – Fat
- Type 10-12 - Super Fat
Most common lengths are:
- Standard - Measures 44-47”
- Extra Long - Measures 50+”
Yo-yo string should be changed periodically. Manufacturers generally recommend changing the string after about 30 minutes of play time. Your string may last longer but be sure to check for fraying periodically. If the string becomes frayed change immediately! Nobody wants a yo-yo turned into an untethered and dangerous projectile!
Slick 6 is 50% Polyester, 50% Cotton Type 6 and usually only comes in lime or white.
Slick 8 is 50% Polyester, 50% Cotton Type 8 and usually only comes in blue or white.
Non-bearing yo-yos will wear out the string quicker.
Also, keep an eye out for discoloration of the strings around the bearing. Dirt or moisture can weaken a string. If the string looks dirty or dark, best to replace it.
Nylon string is not recommended for looping yo-yos because the fast looping movement can cause it to melt (so we hear).
