What in the World is ED Coating? (Video)

Esker Cycles, via a recent four-minute video featured on Bikepacking.com, has offered a detailed explanation of Electrophoretic Deposition (ED) coating. CEO and Founder Tim Krueger elucidated the process, specifically highlighting its application to steel bicycle frames and outlining the unexpected benefits this finishing technique provides, beyond mere aesthetics. The video serves as a technical deep-dive into a manufacturing process often overlooked by the end-user.

This technical spotlight arrives as steel frames continue to carve out a niche in the adventure and bikepacking segments, where durability, repairability, and ride quality are paramount. While paint and powder coating are well-understood, ED coating’s role in corrosion resistance, particularly on internal frame surfaces, is a critical, if unseen, factor in a frame's longevity. Understanding such processes helps consumers appreciate the engineering behind their increasingly specialised equipment, especially as brands like Esker position themselves on quality and performance.

Ultimately, this is a welcome, if slightly niche, piece of educational content. In an industry often fixated on marginal gains and new materials, a reminder that the fundamentals of frame protection still matter is a refreshing, if not entirely groundbreaking, insight for those who truly ride their bikes.
