MucOff Bio Grease

I’d previously written about mucoff BioGrease, and I wasn’t impressed at the time. I’ve decided to give it a bit more of a chance. Previously I’d used it in the wheels, and it went south pretty quick.

This may of been due to the high spin speeds on the hub, the BioGrease is more designed for low rpm high sheer, such as headsets and bottom brackets. So, from here on, threads and headsets will be slathered in BioGrease, and the wheel rebuilds will be the stinky, incredibly tacky blue, which works well in high revolutions applications. So let’s see how it handles the dry summer months.

But don’t forget, any grease is better than no grease, use what you have on hand, and enjoy the maintenance of your bikes as much as riding them. After all, your bike gives you a lot, give it something back!

Muc Off Bio Grease

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.

More Grease

I’ve written before about grease, it’s somewhat of an obsession with me. I’ve got tubes all over the garage.

Anyway, last time I cleaned out my headset (according to maintenance logs, 17th November), I used Park Tool standard grease, and as I had to remove the forks today, I thought I’d do another headset relube. So, looking at the grease that’s left, I was impressed that the bearings where still well covered, and the filth was minimal on the rear of the bearing seat. I’d ridden alot in some proper dirty wet weather, and the park grease had stood up well. A certain amount had clearly washed out, but enough remained to make me feel it would of been OK for another couple of months.

I’ve replaced it now with Crystal grease, which is alot thicker, and I’m pretty sure will stand up even more to the weather. It’s kind of become my goto grease at the minute, But time will certainly tell how it lasts.

After reassembly, the steering felt alot smoother, but that maybe in my head more than anything. One things for sure, crystal grease is alot easier and cleaner to apply than the park grease.

I’ve somehow gained a tube of MucOff bio grease to try out, so that’s another grease to try later. So far I’ve put it in my speedplays (which to my horror the left pedal was dry) but not ridden yet with it in. Muc-off states that it’s very water resistant, so hopefully it should stick around longer than the Weldtite. My speed plays are starting to wear anyway, so the grease may outlast the pedal bodies..

MucOff grease is pretty much the same colour as the Weldtite Tf2 Teflon grease I had been using, but has these weird silver things visible in the grease. I’ve not seen anything like it.
