Fork Oil
High performance fork oils and hydraulic oils in a complete viscosity range. Can be used in suspension forks, rear shock absorbers, dropper seat posts, hydraulic remotes and mineral oil brake systems.
Fork oils are formulated for consistent damping, excellent lubrication and rapid release of air to prevent foaming. For high temperature applications consider Shockcraft Hot Oils. For low volume lubrication (i.e. fork lower leg bushings) consider Lube Oil.
Available in 1 litre bottles or repackaged into 250 ml bottles to make home servicing easy and cost effective.
We are only able to ship up to 250 cc of oil to international addresses.
For more information about selecting the right oil for your bike, check out our series on Suspension Fluids. We've also produced some simple charts here to help you select the correct oils for your brand of fork, terrain, climate and riding.
