I recently picked up a tube of the Bio Grease, and had high hopes for it.
Being an avid user of Muc-Offs chain lubricants, using them all over the bike and SpeedPlays my expectation of this grease was great. However in practice, it’s really a sub par grease.
I’d used it when rebuilding my front hub, and after a short time, the hub had developed a really annoying squeak, and I really hate any odd noise on my bike. So, back at home I took the wheel apart to find out what this offensive squeal was. The Bio Grease I had used in the hub had gone a really light pink colour, and just looked wrong, wiping it off the surfaces, it was incredibly thin. Alot thinner than it should of been. It had obviously soaked up a load of water.
So cleaned that out and replaced with the good old crystal grease. Squeak gone.
So, the bio grease has been placed at the back of the shelf, destined to be forgotten about in time.
