Is the WHEELTOP EDS-TT waterproof, and will it hold up in rain and wet conditions?

The WHEELTOP EDS-TT features sealed electronics and weatherproof connectors rated for triathlon conditions including rain, spray, and pool water exposure, making it suitable for both open-water swimming transitions and wet-weather training. The carbon fiber OSPW cage is corrosion-resistant and the derailleur's compact sealed design protects internal components, though we recommend rinsing with fresh water after saltwater exposure to maximize component longevity.
