I've used this maybe a dozen times, so this is more of a first impression review. I'm a road rider. I haven't swapped out my flat bag CO2 cartridges yet, but that's my intent.
So far I've been using it to inflate my tires at home. The instructions warn you to start the pump before attaching it to a partially inflated tire. It's a little awkward trying to connect the running pump, so I deflate the tires and start from near zero psi every time. It takes less than a minute to inflate a flat 32c road tire to exactly 60 PSI. The first few times I verified the accuracy of the pump's own measurement with my fancy digital gauge. It's spot on.
A number of people have noted that these pumps get very hot. At least with road tires and the shorter inflation time, that has not been my experience. Yes, it gets warm, but nothing close to hot. Battery charging time is super fast - seems like about an hour from a low battery state.
Overall this is a very nicely made!
I had been holding out on moving to wax. My new road bike came with a waxed chain and a bottle of the super secret drip wax. I was really impressed with how long the wax lasted vs lubes and topping off with the drip wax was as easy as lube. So I decided to switch my gravel and MTB to wax. Watched lots of "how to" videos and talked to others using wax. The Silica system seemed to make it easy to do. I have done 3 chains now with the system, no problems and can go about twice as long between lubes as I did with regular lubes. I use the strip chip when I do a full waxing which is much easier than cleaning a chain as it is just part of the waxing process. The hanging feature on the system is really convenient and easy to use. Chain stays noticeably cleaner too, besides being quieter. Not sure if it makes me faster as my new road bike is so much faster than my old but probably doesn't hurt.
Had a flat on my Cervelo on the rear, and of course the Orange Seal spewed all over the frame. Since I was running a 50 on there (super tight, I know, Cervelo needs to up their game on tire clearance), I didn't notice the dried on sealant until I had the wheel off the bike a few weeks later. I had just added more sealant at the time of the flat and that had fixed it at that time. Ordered this stuff, and lo and behold, it managed to get it all off, not instantly, but it wasn't that long to get it all off. Impressive stuff, and it smells pretty good!
When Silca first release this it was met with some blowback based on the price, especially compared to brand x options at roughly 20% the price. Might as well compare Dura Ace to Sora. This is priced at the higher end of any TPU tube but there are design/quality/performance benefits and you may appreciate or discount those values accordingly.
I've tried TPU tubes over the years and generally found found issues that prevent me from being comfortable using them. #1 is flimsy/cheap plastic valve, poorly bonded to the tube. This makes them prone to to leaks and without a retaining nut even the simple act of pressing on a pump head to top off before a ride stresses that valve/tube and can lead to failure. #2 is that the valve itself is often bonded instead of threaded and therefore opening/closing can break that bond.
The Silca design addresses every issue I've ever had (and they have a nifty intro video on YouTube covering this). The valve stem is full metal, threaded. If you're familiar with tubeless, you realize that itself is roughly half the selling price of this tube. It's also got a metal reinforcement plate against the inside of the rim and a retaining nut for the outside to secure the tube. Silca additionally uses a special (patented) welding process for the tube seam that appears to be more reliable than competitor's designs.
There's also one "marginal gain" aspect of the design I was not aware of until I researched it more - the tube color (or lack thereof). Those low price brand-x tubes come in varying bright/obnoxious colors, which I'd considered harmless since the tube is hidden inside the tire. That color comes by adding powder to the TPU mix (which is, at base, colorless). That additive actually reduces the performance of the TPU, making it stiffer, less expansive when inflating, and adds rolling resistance. You'll likely never notice the difference, but it does make one wonder why the manufacturer would be adding cost to the product and process that serves no functional purpose and actually hurts performance a bit.
So haters can hate, but I've finally found a TPU tube that's high performance, high quality, easy/reliable, and I'm actually converting all my bikes BACK from tubeless to using these TPU tubes. The higher price, to me, is consistent with the higher quality and performance that I consider necessary. I will concede, though, that I think these may be overkill/overpriced for carrying as a spare tube whose primary purpose is to get me back home, which seems like a perfectly fine scenario for those brand-x options (even if it means I carry 2 in order to be assured that one will hopefully work).
