Tools needed:

  • 4mm wrench, or multi-kit with 4mm hex-head
  • Four (4) 5mm bolts and Four (4) T-nuts (comes with VH Klap blades)
  • Utility razor

Bolt Assembly with Long Track Boots

  1. Lace down the skate
  2. Remove the tongue is done by lifting the velco strap on the top of the tongue, which fastens the tongue into place. All VH boots come standard with a removable tongue to optimize position for comfort and performance. The removable tongue makes assembly easier then most long track boots
  3. Looking inside the boots locate the slot on the front and back of the boot. This is where the bolt will go through. Using a utility razor ensure that the slot is cut fully to allow optimal access.
  4. Using the 4mm wrench you will push the 5M bolt into position. The bolt head must be pushed past and under the skate liner. For tips and tricks please see the video above "Assemble bolts in Long Track boots".
  5. Once the bolt is in position in the slot on the mounting block and under the liner you are ready to move to the next stage of attaching the Klap to the bottom of the boot.

Klap skate pivot point position

Klap skate pivot point placementThere are many theories of thought for the klap pivot point position for both

performance and for developing skaters based their stage of development as it pertains to the Long Term Athlete Development.

At VH Speed Skating our methodologies are driven by both experience and scientific validation. The VH pivot point recommendation is based on a Masters Thesis by Scott Van Horne Potential method of optimizing the klapskate hinge position in speed skating. This Masters Thesis coupled with Shawn Holman's research as technical writer of Speed Skating Canada's Long Term Athlete Development Model, takes into account windows of trainability for developing skaters.

Abstract

Pivot point placement for developing skaters

Acceptance of the klap speed skate was fully realized on the world speed skating scene in 1997. However, one of the most important unknowns regarding the klapskate was the positioning of the point of foot rotation (pivot point), which is believed to play an important role in optimizing klapskate performance. The purposes of this study were to explore the ankle, knee, and hip joint mechanical changes that occurred when the pivot point location was modified, and to determine whether maximal ankle torques provide predictive ability as to where the optimal pivot point positioning is for a skater. We tested 16 proficient skaters at three pivot point PP) locations, ranging from just in front of the metatarsal-phalangeal joint to just in front of the first phalangeal joint. Of the 16 skaters, 10 were tested at a fourth position; tip of the toe. Push phase kinetics and kinematics were measured on a modified slide board. The optimal PP for each skater was defined as the position that allowed him to generate the most total push energy. Maximum voluntary static torque measures of the ankle and knee were collected on a Biodex dynamometer. Overall, anterior pivot point shifting led to a significant increase in ankle energy generated and a decrease in knee energy generated, with no significant change at the hip joint. We found no significant correlations between the static strength measures and the skaters' optimal pivot points.

Klap Skate Cone Maintenance

Klap cone maintenance- gluingYour Klap skate cone on your blade can come loose due to extreme cold weather conditions or due to a crash. If you find the cone has come loose there is a easy solution to fix it using super glue. Click on the video icon "Klap Cone Maintenance Gluing" for instructions on this easy solution.
