TECH Cartridge Fork Oil 5 Liters

Cartridge fork oil for the TECH e39 e-moto fork, supplied in a five litre container. SKU SB40224-00.

Fork oil breaks down with heat and use, and old oil is why a fork that was fine last season now feels harsh over small hits and vague over big ones. Five litres covers several rebuilds, which matters because mixing oils of different weights is how a fork ends up damping unpredictably.
