How to Choose This Fork or Shock

A front fork is specified by four dimensions: tube diameter, overall length from the top cap to the axle centre, axle mount type and brake mount. A rear shock is specified by eye-to-eye length plus mount type (eye, clevis or stud). Measure on the bike — a catalogue photo cannot tell you the axle offset.

Spring rate follows rider weight and typical load, not the bike model alone, which is why we ask for both. Every unit is stroke-tested and leak-tested before packing, and damping oil viscosity is checked per batch.

Confirm Before Ordering

Measure tube diameter with a caliper at the upper stanchion, not at a painted section.
Measure overall length from the top cap to the axle centre line.
Confirm the axle mount (single-sided, double-sided or clevis) and send a photo of the brake caliper mount.
Tell us rider weight and typical load (solo, two-up, luggage) so the spring rate is matched.

Ordering and Quality Control

Minimum order: 100 pairs per model; different lengths and finishes can be combined in one shipment.
Samples: A sample pair can be supplied so tube fit, axle mount and brake mount are confirmed first.
Lead time: 15–30 days after deposit, express options for urgent restocking.
Quality control: Every unit stroke-tested and leak-tested; chrome plating and seal fit inspected; damping oil checked per batch.
