Why a sliding hook?
Kitesurfing with a sliding hook is not the fashion of the day but has been developed and tested during the last 10 years, makes kitesurfing more similar to surfing and snowboarding, limits 80% of side pull rotation, it eliminates the need of keeping the harness loose and rotate like many waveriders do, gives body freedom to find the optimal position on board, limits back stress using seat harness, great help in toe-side, can’t miss it in waveriding or snowkiting , improves race performances, helps in body-drag and beach walk.
Does it helps to prevent lower back pain?
Lower back pain is more common when you are an over 35 and did not much sport. You feel it more when using a seat harness or a well tied waist harness (loosen waist harness simulate a DYNABAR but it goes up, hook doesn’t return back to central position and it scratches wetsuit or skin). Many customers report it helps specially if you surf toe-side (it stresses lower back muscles).
How does it affect the performance of jumps with rotations?
DYNABAR affects rotations if you use the kite loops to rotate and you just hang on hook statically. If you are more dynamic and hang on arms you don’t feel it. DYNABAR V7 has a FR slider who gives more stability to the hook, XT has a pivoting and fixed hook to satisfy all needs.
What option to use?
DYNABAR V7 XT has 5 different options the kiter can buy and use.
FR slider is recommended to beginners and free riders who like to jump and rotate hooked.
PW slider is the choice for wave riders who likes to move quickly when playing with waves (see picture above of Simon Gill, SnowRace 2012 world champion, surfing with no control bar in hands!)
PR dyneema was introduced to give the possibility to keep a specific hook position and body direction. The most common style is FR snowkite and racing in water or snow.
Pivoting hook is a good alternative to fixed hook, more strong (minimum metal stress) and less bar movement due to the small leverage (the hook locher is only 3cm high). More important, many freeride kiters have experienced unwanted CL unhook, this is due to side pull. For example when you ride toe side the kite pulls from side and the CL could exit the hook. Pivotinh hook follows the pull direction and CL will never unhook.
Fixed hook is standard, but the hook is fixed to an 8mm rod, connected to frame with nuts to limit possible steel rod failure (it is due to pull right-left-up).
