The Ultimate Wear Reducing lubricant for E-Bikes. Based on our own award winning Synergetic lubricant, the first and only wet lube to record a 0.0% wear block in Zero Friction Cycling lab testing, Synerg-E takes our patent pending Tungsten Tribofilm Technology and blends it into a higher viscosity lubricant optimized for the high torque experienced in E-Bike drivetrains. E-bike chains experience more than 2X the internal pressures of traditional bike chain, and are capable of wearing out expensive drivetrain components like chains, chainrings, and cassettes at more than twice the rate of traditional bicycles. By increasing viscosity and adding Calcium Sulfonate to the mix, Synerg-E gives up roughly 1 watt of pure efficiency to Synergetic, while nearly doubling the oil film strength to ensure the lowest rates of chain and drivetrain wear of any lubricant currently available. As with all SILCA lubricants, Synerg-E uses only the finest, environmentally friendly pure synthetic base oils with additives approved as safe by the EPA and Bureau of Land Management. Synerg-E contains NO PFAS or other Fluorinated chemicals.
