Profile Design J4 Bracket Kit

8 Points of Adjustment via one Single Bolt 
Extension length and rotation adjustment is controlled by just a single bolt. With 8 points of adjustment, the J4 Bracket can be fine-tuned to the millimeter to optimize the aero position. 

  • Reversible armrest position 20 mm behind or in front of the center of the base arm
  • Unlimited height adjustment of up to 60 mm with a constant angle by wrist compatibility of clamps with Profile Designs riser kits
  • Adapting of the extensions is quick and easy with only one screw
  • A patented, linear wedge prevents power peaks at the clamping. Because of its hidden position, it increases the aerodynamics.
