Bontrager TLR Sealant

As with most folks, I've been mainly running the Stan's tubeless sealant since I dumped tubes. Other sealants I've tried are either a NoTubes tire sealant equivalent for more money or they have some side effect like nasty rotting fish smell or 'did that sh*t really eat through the tire on my spare wheel?' 

I'm happy that Bontrager decided to keep it simple for their TLR tubeless tire sealant. It may be slightly less viscous than Stan's but in my experience performance is identical.

Just add sparkly glitter for the full Unicorn-Poop effect. 

Given similar performance why give a shake* about Bontrager's TLR option? At $25 (USD) for Bontrager vs $28 (USD) Stan's that's a free quart of solution for every 8.5x purchased. It adds up!

In all seriousness though, I always seem to need sealant at the last moment and it's good to know other options that work.

Thanks to Lou's suggestion, I've been using this for a couple years now. 

It seems to work at least as well as anything else, although I've never tried the "Stan's Super Mega Race Sticky Ultra Super-gooey FRO Special Formulation 42" or whatever they call it.

Sweet, sweet, crazy Uncle Lou @ Obsession:Bikes. He's given me so much great bicycle advice over the years...

Which reminds me... it's almost Valentines day:

I bought a few bottles of this stuff in the 2oz size back in the fall. Went to use it a couple weeks ago only to find that the sealant goop (consistency of baby milk in barf form) had separated from the liquid. All the bottles had the same problem even after vigorous shaking. Mind you they were stored in my garage during our 'cold snap' but stayed above freezing in the garage. I wasn't expecting problems since the bottles are freshness sealed, and I've had open bottles of Stans in similar conditions with no issues. Maybe just a bad batch?

I've had that happen - admittedly years ago - with a couple of different sealant products in the little 2oz bottle sizes stored indoors. It's actually what prompted me to only buy the quart size containers since. It was a long time ago and I now only buy the larger containers and store them in a heated basement so I'm not the best person to comment on storability of various sealants. 

Have never had separation issues with larger containers but I do go through sealant fairly quick.

I've always had the best results from the Orange brand stuff... and it doesn't seem to create "Stanimals" as readily as Stans.  How's the stanimal creation with this stuff?

I only seem to get Stanimals in the drier months. It’s rained a lot since August so while I haven’t seen any yet I don’t know that it means anything.

Stans  RACE sealant FTW.... best I've tried.. not the regular stuff.    I've had rides saved with the RACE variant.   Much more aggressive at sealing punctures.

Interesting; haven’t tried it. Any negatives to speak of? Dries faster?

Can't inject it through valve, too likely to clog (must be done the potentially messy tire-off way)

About a third more expensive ($11 per quart) - probably only worth it in certain scenarios (thorn city, aggro rider in rocks, paper tires, race day etc.)

Other than that, no. (Stans claims it stays liquid as long and so far I believe it) Good stuff IME
