New Continental 5000S Tires - Tubeless Compatible

The one thing I have not found yet is a good way to check the level/condition of the sealant without unmounting the tyre. Any tips from others?

I'm intrigued by this and am going to give it a try with my next tubeless setup:

Reading reviews, the downside is that their valve cores are proprietary, so if you somehow break one, you need to buy a whole new valve. In theory, the valve core should not clog because of the design of the valve. The proprietary valve probably does not meet weight weenies standards either!

Shake. If you can hear the sealant you're good, if not top it up.

Thanks. Inspired by this tip, I found a better answer to my own question: https://www.giant-bicycles.com/gb/tubel ... ck-syringe

I don't think Milkit's proprietary valves are useful - I really do not need the ability to check levels without deflating the tyre - only without removing one. Deflate, remove valve core; reflate - this is all 2 minutes work.

Shaking is not scientific enough for me: I'd like to keep between 25 and 30 ml of sealant at all times in an ideal world.

Those MilkIt, Giant, Odier, etc. syringes will get clogged by pretty much any sealant that uses tiny particles.

Yeah, that’s a risk. I’ll test the Giant one and let you know. Washing all sealant off with water seems a must after each use.

It may seem pretty simple, but Orange seal makes a dipstick. Simply remove the valve core and drop in the dipstick just like checking the oil in your car. The hashed section of the dipstick is about 1/2 inch. Alternately you could use a spoke and use the threaded end for the measured section. If you take a tire that you just filled with your preferred amount and stick it, you will know your level. I find that every 3 months that I need to add about an ounce of sealant in Southern California.

I agree about the mikit valves. A waste of time and money. I never check sealant levels in my own wheels.

@TobinHatesYou since you are orange seal fan boy do you know how long the shelf life of the sealant.

last year i bought a bottle of orange seal (manufactured date is 12/12/2017). i never used it last year but will get some new conti tires in the spring . is the sealant still good?

The best sealant is almost always going to be Orange Seal (regular.) It has the best combination of sealing ability and endurance/lifetime. Some "thicker" formulas like Stan's Race will plug large punctures, but at the expensive of endurance/lifetime and it tends to clog valve stems.

[TobinHatesYou]

I buy the 32oz bottles and they last more than a year. I’ve heard about the sealant separating, but dive never experienced it and don’t know what conditions causes it.

Read a review on WIggle, not a glowing first impression of the TL - leaking sidewalls; got to believe the person fitted them correctly. Anybody else used them on at least a few rides by now?

Would be nice if there was a 4season and/or gatorskin version in the longer term, need more choice, run One Pro's but boy they don't last long (so far).

[bm0p700f]

Well I have a pair that dont leak and none of the ones I have sold (10 pairs so far) have leaked. I assume customers would tell me.

More choice? Gator skin tubeless? The clincher version is like riding on a wet road in the dry why would you want a more expensive tubeless version of that. 4 season are the most unreliable tyres I have ever used.

You dont want more choice but tubeless versions of the tyres you currently use. Switch to another brand. there is already plenty of choice.

Lets list them road tyre in normal road sizes.
Conti GP5000TL -
Schwalbe Pro one
Hutinson fusion 5 Performance
Hutchinson fusion 5 all season
Hutchinson intensive
Hutchinson Sector (there your gator skin tubeless tyre right there)
MAvic Yskion UST
IRC Formula Pro X Guard
IRC Formula Pro RBCC
IRC formula Pro Light
IRC Roadlite
Specialised S-Works Turbo Tubeless
Panracer Race A EVO3
Vittoria Corsa Control G+ tubeless
Vittoria Rubino Pro G+ tubeless
Vittoria Corsa Speed - fragile
Brontrager AW2 TLR
Bontrager R3 TLR
Bontrager R2 TLR
Zipp Tangente Tubeless

Have I forgotten any. really not enough choice.

I have a pair of 25's on hold for me at my lbs, picking them up early next week and will provide fit details and such once mounted, probably on Tuesday. FWIW I've been on tubeless since about 2013 (mixed with clinchers on different wheels, exclusively tubeless the last couple years). I enjoy trying new tires and have so far from a tubeless standpoint used:
Bontrager R3's
Huchison Fusion 3's (I think)
Schwalbe Pro One
Schwalbe Pro
Specialized Turbo
And others that I can't quite remember, so point being I should have some credibility when it comes to mounting experience

[petromyzon]

Meh. He should try installing a set of Compass Ultralights and then complain about weeping sidewalls.
As he/she freely admits they sent a tyre back after getting a single puncture on it I'm not surprised they have taken to a large website where they did not buy the product in question to vent their misunderstanding of probabilities and risk.

[bm0p700f]

Wiggle could delete that review and they would be right to do so. If the tyre was not bought from them then no review should be left on there site.
