Two-ways. Done properly.
There is one simple reason why Two.Zero shocks don’t have bump canisters: We found a better way.
Don’t argue with physics.
Damping is a resistance to force and force is a function of pressure and area. Canister shocks resist bump forces by restricting the flow of oil displaced by the shaft—in effect applying pressure to an area equal to the diameter of the shaft. Two.Zero is different, only restricting flow across the piston—which is much larger.
Why is that so important?
Applying pressure to a larger area means less pressure is required. The reduced hydraulic pressure means the damper is more efficient, particularly at low speeds and when it changes direction, right where you need it the most.
Value added confidence.
Two.Zero has two colour coded adjusters that each effect bleed across the piston in one direction only—benefiting you with superior performance and truly independent two-way adjustment. No bells. No whistles. No canisters. Just good. Common. Sense.
