BikeYoke Sanguine Hydraulic Oil

While this oil is specifically formulated for BikeYoke seat posts, its low-friction properties and seal-conditioning additives may work with other hydraulic systems. However, we recommend checking your specific post's manufacturer guidelines before using it to ensure compatibility with your internal seals.

The Sanguine formula is engineered to maintain a consistent viscosity even in sub-zero conditions. This prevents the sluggish, slow-return feeling often associated with standard hydraulic fluids during winter rides.

Yes, it contains specialized additives designed to keep O-rings and seals supple and lubricated. Regular maintenance with this oil helps prevent the drying and cracking that often leads to premature seal failure.

A 250ml bottle is more than sufficient for multiple full services. Depending on the specific model of your seat post and the amount of fluid required for a bleed, you can expect to get several years of maintenance out of one bottle.

This is a hydraulic fluid intended for the internal hydraulic circuit of your seat post, not for external lubrication of the stanchion. Using it internally ensures smooth actuation and proper seal health.
