Silca Ultimate Sealant, 1000ml
5 rating
by Steve F
Saugus, MA
Much easier to work with.

I'm using Reserve Fillmore valves so I wasn't able to inject this stuff but I still used a sealant injector to get it into the tire without making a mess and it did not clog. I've already had a small puncture that sealed but it did take a while, it was close to the sidewall and I probably didn't have enough sealant in the tire to be honest. I didn't look at the recommended amount for the size tires I'm using so I should have added 15-20ml more. Assuming this stuff lasts at least a few months and the fiber foam stays suspended in the sealant rather than gathering along the tire bead making it less effective then I will buy it again. It is expensive but so far so good and it is a vast improvement over the original stuff as far as usability goes.

Dynaplug Racer Pro Tubeless Tire Repair Kit
5 rating

Perfect tool for tubeless tires

Upon receiving the dynaplug pro repair kit I threw it in my seat bag and was off on a ride the next day. My buddy was running tubes and within 15 minutes he had a flat. Pull the wheel, fight with the tire, pull the tube, reassemble, reinflate-15mins pass. Back on the bikes riding and 2ish hrs later I get smacked with a flat. Significant gash about 1/8' long, tire sealant leaking out. Position the hole at 12 o'clock push a dynaplug in, push a second one in right next to it, position the hole at 6 o'clock for a few seconds and reinflate. Holding air no problem, back on the bike in 3 mins and finish out our ride no problem at all. Got home trimmed off the excess plug and been riding it for the past month.

Quarq TyreWiz 2.0 Air Pressure Sensor for Presta Valve
3 rating

Much better, but not quite there yet

The Quarq TyreWiz 2.0 Air Pressure Sensor for Presta Valve is an improvement over version 1. There is no "wrong side" to view the indicator light, the risk of leaks due to slight manufacturers' variations of threads of the valve stems eliminated.

However, the adhesive strip material that bonds the body to the wheel does not work well with the curve of the road carbon wheel. Also, threading the inflator unto the stem has loosened the securing nut which caused me to lose a canister of CO2 on leaks at the Tyrewiz.

I still have in on my road wheels. Just gets a little getting used to.

Useful, somewhat improved, could have been much better

I've been a fan of Tyrewiz ever since they first came out, because it helps me keep tabs on my tire pressure and keep it all very consistent. Sometimes I'd feel the rear of the bike step out just a hair. In the past I'd stop and give the rear tire a pinch to make sure I'm not imagining things. With Tyrewiz, I just glance at my cyclecomputer and keep rolling, no big deal. It was also fun and educational to see my tire pressures go up about 1 psi as they warmed up riding in the sun.

Like another reviewer, I have mixed feelings about this 2.0 model. For starters, the price is very high and on top of that you have to measure your and buy special valve stems. Those valves are a significant extra cost, can be difficult to find (I waited for months in one case) and you need to use a special tool when you're adding sealant through the valve stem.

Also, the battery is unchanged. This is a big miss, because the old battery never lasted long enough on the 1.0 model. If you have just one bike, maybe no big deal, but if you have a few it feels like you're constantly swapping them out. I really wish they would have taken the opportunity to switch to a longer-lived battery. At least the batteries are easier to change than before (see below).

Depending on what rim you have, getting these to sit nicely might be a challenge. Some rims (like the Light Bicycle AM930S) have rippled internal diameters. If you have one of these rims, you'll need to make a run to the hardware store to buy some rubber washers to fill the valley between spoke holes.

Cyclecomputer support is still kind of hit and miss. Garmins only support Tyrewiz through the ConnectIQ app. This app used to be extremely flaky. It seems to be working better now, but I'd like to see real factory support from SRAM on this. On Hammerhead Karoo, the support is quite good, but you have to consume a whole data field for each tire. I'd really prefer to see one field service both tires simultaneously.

I'm also concerned whether the protocol and pairing will work correctly if other Tyrewiz riders are in the vicinity. Rumor has it you might pick up someone else's tire pressures, which would be incredibly annoying.

On the positive side, this form factor seems far more robust than the goofy "flag" style from the 1.0 product. I actually had the flag rotate once and snag on something while descending a flight of stairs, breaking the valve and causing an instant flat. Not cool. This isn't an issue at all on the 2.0 product.

The 1.0 product was really fiddly the change batteries, and the battery contact points were also super fiddly. I used to have to frequently use a jeweler's screwdriver to gently bend the contacts so they'd keep the battery connection alive. Knock on wood, the 2.0 version is very easy to change batteries and the contacts are working better.

As another reviewer noted, one downside of the 2.0 form factor is that using tubes with these is out of the question. I never tried tubes with the old version, but given the "flag" form factor, they should work fine.

Overall, these Tyrewiz 2.0's are better than the 1.0 versions, but they're more expensive and not as much better as I hoped for. The value proposition is kind of meh, so I'd only recommend these to someone who really wants live telemetry of their tire pressures.
