Colours Grey,Black, Red.                                     Ronstan pulleys with spliced and sewn  hang point.

  • The pulley is supplied as standard as a pair without a dyneema hang point.
  • Spliced and sewn pulleys can be bought from jonnie eisler on line shop
  • Durable lightweight pulley with white  plastic sheaf (roller). 
  • To service pulley  clean with fresh water  after use. 
  • Check pulleys for wear,and tear and replace when needed.
  • Check white roller (sheave) for chips,burrs,alignment, (buckled) and freedom to roll.
  • Broken or jammed pulley will  ruin a kite bridle, and alter freedom of control.

What a worn white sheave on a Ronstan pulley can look like.

 The side wall on one side of the sheave has  worn away, causing bridle to snag and slip down the  side of sheave, whilst damaging

the bridle,it also  buckled  the sheave.

The pulleys are worth Checking, before replacing the bridles, at a cost of 7.50 a pair.

This could be  be a very worth while investment once a year, I do replace a lot of pulleys when servicing a kite.
