Sidecar Leading Link Sidecars Leading Link forks. The front fork bicycle system defined in claim 2 said linkage is comprised of pivots and lever arms arranged in a leading link geometry including as part of the linkage one or more shock absorbing units and at least two springs and wherein said at least one shock absorbing unit is a rotary shock absorber and said two springs are each. Why are they better.

Leading links were lighter than telescopic forks although they looked heavier. In practical it reproduces the geometry of the rear fork along with a n arm that usually rests on a fulcrum which is placed on the steering column making the fork rotate in one piece along with the steering head. Depending upon whether the arm is compressed or extended during braking leading link or trailing link front forks are discovered.

Our leading link kits can be manufactured for use with original fitment wheel brakes and tyres or to suit your own choice of wheel and tyre discs and callipers. Telescopic forks were designed by the manufacturers for bikes with two wheels leaning into and out of corners and the ability to self-centre. The larger the rake angle the further forward the front wheel will sit which gives it the chopper look.

They were also great Earles fork lead link design whether it be slow or high speed when used on a solo bike such as in the photo of my R69S. You now steer the bike instead of leaning. Leaning into a turn and self-centring action.
