Rock Shox 154093 Reverb Hydraulic Fluid Bottle, Red, 120 ml

It’s oil, for your seatpost.It comes in a plastic bottle and is foil sealed.What more can you review?!?Ensure you have the correct bleed kit and buy the correct oil for the part you are bleeding. There’s nothing more to say about this product.

Good

I serviced my rockshox reverb and used this to bleed the system. Like brand new afterwards.

It's oil what do you want me to say

Used this oil to fix my seat dropper, still got enough to rebuild two more times

Enough oil to do a full service on my post with some left over

The best fluid you can get for the reverb.
