Was scouring a few suppliers the other night, looking for vapourware, and noticed a couple of other tire/tube manufactures are doing similar style of tubes to Tubolito. I invested in my first set of Tubolito's on my 700 x 40 non-electric gravel bike which was until now tubeless. Nothing against tubeless, and I still run tubeless on my fat bike, but I am thoroughly a fan of the Tubolitos. The gravel bike when aired down feels just like tubeless.
I have built very much upgraded wheels for our Como 5.0 and Vado 5.0, more for a strength perspective (and because I can). Took the Vado to 27.5 so I could fit in some Super Moto tires. Very comfortable, and even more so with the new tubes. Fortunately we don't deal with many thorns in our riding area, but I do carry the Tubo flat repair kit just in case. Will change my Levo over to Tubolito too when they become available again.
