Fox Terralogic fork


Fox Terralogic fork

This version has the following vital stats:

  • 2012 model for 26" wheel size;
  • FIT Terralogic damper;
  • Kashima Coat stanchions;
  • set at 80mm travel (may be possible to increase travel to 100mm or even 120mm);
  • tapered steerer (1.5" to 1 1/8") - even though this is on a Giant XTC frame, thankfully it does not use Giant's Overdrive 2 steerer with the 1 1/4" upper tube size;
  • 15mm thru axle;
  • 160mm PM brake mounts, max rotor size is 203mm.

Terralogic?

Here's what Fox has to say:

    The Terralogic damper contains a weighted brass inertia valve called Brassmass, which freely slides on a shaft to open and close compression flow ports in the damper.
    The Brassmass assembly automatically responds to the impact of bumps or potholes in the trail, opening the compression flow ports and allowing the flow of damping oil. The Brassmass assembly does not respond to rider input (pedaling, sprinting, G-outs), keeping the compression flow ports closed and maintaining the pedaling platform or the feeling of fork lockout. With the patented timer circuit constantly in control as you ride, the transition between maximum pedaling efficiency and low speed damping control is nearly instantaneous.
    The Terralogic threshold is an adjustable compression blow-off valve that bypasses the Brassmass assembly, adjusted with the blue knob located on the bottom of the right fork leg. This knob enables you to regulate compression platform when the Brassmass assembly is closed.
