E-bike riders, and endurance riders in harsh conditions, who put chain life ahead of the last watt.
Silca Synerg-E is based on Synergetic, the wet lube that recorded a 0.0% wear block in Zero Friction Cycling lab testing. It blends the same tungsten tribofilm technology into a higher viscosity oil with calcium sulfonate, which Silca says nearly doubles the oil film strength.
The maker developed it for e-bike chains, which see more than twice the internal pressure of a normal chain and can wear chains, chainrings and cassettes out faster. The trade off is roughly 1 watt of efficiency compared with Synergetic. It contains no PFAS or other fluorinated chemicals.
Made for e-bikes
Higher viscosity for high torque drivetrains.
Stronger oil film
Calcium sulfonate nearly doubles film strength, says Silca.
PFAS free
No PFAS or other fluorinated chemicals.
Lubricant
Great for
Maybe not for
One 59 ml (2 oz) bottle. Silca says it gives up roughly 1 watt to Synergetic in exchange for stronger oil film.
Chain choice
Because it is thicker than Synergetic, it suits high torque drivetrains. If you ride a regular bike in fair weather, Synergetic is Silca's faster option.
