Made from brass and weighing in at
42g, which is 39g more than the rear hinge pin brace it replaces

Sits perfectly just in front of the rear wheels which greatly removes the pendulum effect that rear end weight kits cause.
The price is £20 plus postage as per the sticky at the top of this section.
