Engineered for high-performance suspension applications, these Pro One fork tubes are sold in pairs and offer a range of specialized surface treatments to suit specific riding conditions. Options include traditional Hard Chrome, Black DLC, and Gold Titanium Nitride (TiN) coatings. The DLC finish provides an extremely hard, corrosion-resistant surface with reduced friction, while the TiN coating utilizes a hard ceramic material designed to minimize friction and enhance wear resistance. Riders should note that these specialty coatings require additional care and maintenance, as they are not resistant to scratches or dings.
When selecting the appropriate tube diameter, it is critical to verify compatibility with existing suspension components. Specifically, 39mm fork tubes are not compatible with the stock spring internals found in 1999–2005 FXDX models. Ensuring the correct fitment is essential to maintain proper suspension function and avoid installation issues. These hard parts are designed to deliver precise performance characteristics, allowing riders to tailor their fork setup with confidence based on verified technical specifications.
