I have run the 45, 50, and both color sidewalls of this tire over the past year. It has proven to be very durable, fast rolling, and hooks up well in the rough stuff. The transparent sidewall seems to weep more than the black wall until the sealant sets up. No problems after the initial setup when it comes to holding air. Measures as stated on 25mm internal hookless rims. Other tire favorites of mine are the Tufo Gravel Swampero (love it, just want to run larger than 44) and the Mezcal, (same, want to run larger than 44). This has been a great choice for a 45-50 aggressive gravel tire.
First ride of the season and I was washing my bike afterwards. Found a good sized wood splinter sticking out of my tire sidewall (not the usual pin prick like a thorn or something). Never even noticed it during the ride. I pulled it out and it sealed immediately. Amazing stuff.
I also change out my sealant every season so I can see that it's still in good shape from the prior season. Unlike the first gen Silca ultimate sealant which was completely dried out and useless within months.
Fantastic little device that is a must-have if you ride tubeless, IMO. The mount does appear a bit flimsy at first glance, but I've ridden thousands of miles both on my road bike and on my gravel bike with these things and have never lost a plug or had any issue. (I suppose you could use some electrical tape to add a little extra security to the plug/mount if you wanted.) I've had to use the plug only twice in all those miles, which I think speaks to a good tubeless setup, a quality sealant, a good helping of sealant, and good tires. The times I did need to plug, I fixed the punctures straight away and was rolling quickly. I now ride with two plugs/mounts on both my bikes, attached to the bottle cages, so that I can be ready for punctures and otherwise just not have to think about flats. (P.S. I now race cyclocross almost completely on tubeless tires and keep a plug on my CX bike as well, just in case. So far, so good.) My only complaint is these suckers are sure expensive. But for me it's a little extravagance that gives me peace of mind.
I build vintage racing bikes and prefer tan wall tires for the period "look". These tires are at a terrific price point to help keep my projects within a budget, yet they are attractive and perform reasonably well. There are tires that are longer-lasting and provide better grip, but the overall value of these tires is hard to beat.
