It's been five months since I switched to tubeless tires. I've finally gotten around to adding sealant to them. Here are the steps I took:

1. Took the front wheel off the bike
2. Remove the valve core (*)
3. Position the wheel so the valve is parallel to the ground
4. Screw on the tip of the Stan's ToTube sealant injector
5. Add sealant to the injector
6. Inject sealant
7. Put the valve core back in
8. Inflate the tire
9. Put the wheel back on the bike
10. Repeat for the rear wheel

(*) I should have deflated the tire first so the air won't blow off the valve core.

I am all thumbs, so I was naturally very nervous. In the end, everything worked. I did have to clean the garage floor as sealant was spilt all over the place. At least it will be a lot easier from the second time on.

5 months is a long time. Did you check to see how much liquid sealant you still had? Of course it varies with tires and sealant types, but I'll go about a month between checking sealant levels. I probably top off about every other time I check. I use a wire as a sort of dipstick. Rotate the valve stem to the bottom and wait a bit for sealant to settle, then put the wire in and pull out to see how much I have.

Also, why take the wheel off the bike?

I don't know anything about screwing on a Stans injector, though I think I know what that means. In my case I just have a syringe with a tube that fits through the valve stem. I position the stem at about a quarter the way up. I give the tire a squeeze and slowly release the squeeze as I squirt in the sealant. That keeps from blowing air and sealant back out.

We all have our own way and you'll figure out what works best for you. And I'm sure you'll get to where you don't have sealant all over the place.

With Orange Seal Endurance, even here in north Texas when it gets plenty hot in the summer, I generally don’t worry about adding sealant until 4-5 months or more. In fact when I’m riding a lot it’s not uncommon for me to wear out a pair of tires without ever checking or adding sealant.

I don’t bother taking the wheels off either.

x2 If the tire doesnt wear out, something destroys it, or I get a puncture that calls for adding in more goopitygoopgoop.

I was first going to check the sealant level in 3 months, but I asked the LBS and they told me that I should be okay as long as the tires hold air, so I procrastinated until today. Not that the tires started losing air. Just that I somehow felt like it was the time to get to it. Not scientic, I know...

And yes, I will deflate the tire first before removing the valve core.

I sure made a lot of mess this time. I'm at least more confident going forward.

I use the regular version of Orange Sealant. Do you two know of any cons with using Endurance vs Regular?

Troul 

the regular stuff runs thin & might not seal up holes that are on the larger size for what it is expected to address. Additionally, the service intervals in between fluid top-offs/checks is less frequent when using the regular version.

If you are going to hold to the tight service schedules, you might be better using the other one... if punctures are a nuisance.

Did you check for and water from old sealant before adding any? This is Bontrager sealant after 6 month. I added some at 3 months.

It’s been a year, probably need to check fluid levels. With GP 5000s I only lose a lb or two between rides and the tires have proven to be bullet proof. Can’t count how many times I have ridden through broken glass without a flat. Amazing tire technology.

Same here, even though I got less than 2 months with the regular Orange Seal I am going on 5 months with the Endurance formula and still good.

I originally used Stan’s Race but found it didn’t always seal quickly. I read about Orange Seal, and haven’t looked back. I’ve probably run both versions. I know the last couple of bottles have been Endurance for sure. But the first few bottles could well have been either. Probably have 35,000 miles or more since switching. Pretty sure I picked up at least one or two bottles of regular over the past 4 years. No complaints from either.

Yeah I'm very happy with the GP tiries in general. Rode three sets of GP 4-Seasons in 7 years with two flats. Now I've been with the GP 5000 AS TRs for 5 months, and no flats so far.

Orange seal endurance for me as well, and 4-5 months sounds about right.

GP 5000 S TR is the best tire I've ever used, hands down. That said, I had an unfortunate run of flats with them earlier this year (3 flats in 2 weeks, each one trashed the tire - in all cases it was gashes caused by broken glass so I don't blame the tire). I couldn't immediately source more GP5K's so I switched to Specialized S-Works Turbo T2/T5 and have been very happy with those.

rsbob 

Also have to recommend Schwalbe Pro Ones. They too have proven to be trustworthy runners.

Thanks guys! I will most definitely get the Endurance when my current bottle runs out.

Orange Seal Endurance lasts longer but doesn't seal as well as regular. I used to use Endurance, and with Seattle's temperate climate plus storing my bikes indoors, it seemed to last half a year at least, so I switched to regular this riding season. The season's winding down so I'll probably be removing the excess later. Doesn't seem like I need to top it off yet -h I have the OS dipstick but can't use it to check sealant levels because I also installed Vittoria Air-Liners this year.

msu2001la

I've used both Orange Seal regular and endurance in the past. I didn't really notice much difference.

daihard 

Thank you! It really helps to get another rider's experience in Seattle. I also store my bike indoors. I will talk to my LBS for their opinion, but at this point I'm leaning towards continuing to use the regular version.

[ADD] I like the dipstick that comes with the Orange Sealant bottle, too.
