ROOSTER Custom Cycles is continuing its re-introduction of the Perse line of components with the addition of the Girder front end.Unlike conventional telescopic front ends, the Perse Girder fork’s leg does not change length during braking, which results in a reduction of brake dive under heavy braking.
The leg length of the billet aluminum Girder fork is calculated to allow 4in – 5in of wheel travel. Further billet aluminum is used for the construction of the triple trees, A-arms and axle blocks, and there is a choice of 3/4in, 1in or 25mm axle fitting. High strength 17-4 stainless steel is used for both the axle, and the steering stem and the left-hand threaded hidden axle is locked in place with a Perse ‘Pinch Lock’.
The complete front ends are supplied with upper and lower triple trees, steering stem, fork-stop, A-arms, legs, axle blocks with brake mount(s) for Brembo calipers, axle, integrated headlight, and a Penske shock. Fork blade options include plain, recessed dimples, through and through holes, or custom ‘tattooed’ engraving. Some finishes are available at no extra charge.
