Great race day sealant. Does not last months, rather weeks.
I have used the silca first and update sealant and its refill for over a year on gravel, road and MTB tires. Had great luck while the sealant is fresh. After weeks, sealant is exhausted and leaves a huge mess throughout the tire.
If you leave the bike stationary for a week, you'll find a large ball of coagulated sealant at the bottom, which results in unbalanced wheel and fun/terrifying speed wobble
As mentioned by multiple people, stem and valves needs constant cleaning
.
It's perfect if you use the same wheelset on daily bases and wear through tires every few months. Beyond that, i would stick with something less sticky
My gravel bike serves double duty as my year round commuter as well. While these tires don't have the greatest puncture protection, they're a good value compromise since I don't have multiple wheelsets or a MTB and I like to enjoy some off-road fun occasionally and these perform really well on light to moderate gravel and easy single track. Though the protection isn't amazing, it's not horrible especially for the price, and they tend to seal up reasonably well with Orange and plug easily with cheap bacon strips when the sealant isn't enough on its own. I've found them to roll nicely on either paved or not, unlike some other gravel tires I've tried - looking at you GravelKing SK's. They're not too difficult to mount tubeless, though I do find I need to top them up every couple days. Panaracer, Goodyear, and Schwalbe tubeless tires that I've tried all held air a bit better, but had other tradeoffs I didn't like. Durability is also decent but not amazing - I've gone through a few sets of these and they tend to last about 2k - 2500 miles. I'm 205lbs so that's about average for me for tires. The Goodyear Connector I tried was going strong at 3500 miles until it got a large cut, but it felt noticeably slower than these Terra Trails. These are a bit of a Jack of All Trades; don't do anything really great but are solid on just about everything. Being that they're on the low end price-wise of tubeless gravel tires makes these my go-to.
I have Campagnolo Bora Ultra carbon wheels on a couple of my bikes. On a hot day the valve of the front wheel pushed through to the inside of the wheel causing an instant flat. That valve had a conical kind of triangular shape which enabled the failure. The ENVE valves are, by comparison, have a long and rectangular base which fit the rim valley perfectly and, once installed, allowed me to pump up the tires with my old Silca pump as quickly as pumping up a tubed tire. This is especially important as on the road puncture management with tubeless tires can be especially difficult.
The Gravel H tires are the first 45c tires I've had experience with so a big caveat in terms of a comparison to other 45c tires. I chose this one for a durable and long lasting do-it-all and so far it fits the role.
Grip is good and handling is more than adequate. A little slippery on slick wet mud as expected. On dry bumpy terrain it excels in smoothing out the edges of the rocks.
It is a heavy tire, no getting around this. I noticed this as coming from 35 and 38c tires, these take more effort to spin up.
