Say what you will about the performance claims of polyurethane tubings. Are they truly as fast and light as brands indicated that they are? Should you really consider switching from latex or ultra-thin butyl? That’s neither here nor there, because Tubolito’s brand-new X-Tubo City/ Tour inner tube isn’t proceeding after concert. These are purpose-built to tackle another issue: flats.
Instead of moving the super ignite itinerary, the X-Tubo City/ Tour travels the super durable road with some sort of ” extremely strong ” variant of Tubolito’s trademark orange polyurethane material.
” With all of the inner tubes Tubolito manufactures for themselves and their competitors, the different genres( i.e. street, CX/ gravel, and MTB) employ utterly different TPU formulas ,” clarified Tubolito’s US media relations agent, Logan Vonbokel of Haute Route Media.” The X-Tubo also use a wholly different TPU formula when compared to other modelings, “whos also” how they are able to offer it at a lower cost phase compared to some of the implementation of its oriented tubes that require a much higher level of manufacturer accuracy .”
As you’d expect, the X-Tubo City/ Tour is quite a bit heavier than the company’s other simulates. Whereas Tubolito’s standard gravel tubing gratuities the scales at around 60 g, and the standard City/ Tour at 91 g, the X-Tubo City/ Tour is 130 g. Nonetheless, that’s still lighter than standard butyl rubber tubings — and heaps lighter than thorn-proof butyl tubings — and there are no restrictions on what type of brakes can be used, either.
That weight gain hints an increase in wall thickness in addition to the chemical formulation itself, but either way, Tubolito claims the changes dramatically improve the puncture resistance of the X-Tubo City/ Tour — so much better so that the company is offering a one-year warranty against any each type of flats: snake gnaws, glass, nails, tacks, whatever. Tubolito requires you to register the tube within a month of buy, but that seems like a small price to pay. Air retention is likely excellent, too.
Despite the heady claims about puncture resistance, the X-Tubo tubes are still fairly light and compact.
Of course, this doesn’t mean you’ll never flat while using the X-Tubo City/ Tour( surely Tubolito has contracted an actuary to calculate the financial wisdom of such a policy ). There is still questions such as how long it’ll take to get a replacement tube from Tubolito( and how ), what these things go like, and — most importantly — whether they’re even as flat-proof as Tubolito claims.
I’m personally super plotted to try these, although Tubolito regrettably is initially merely offering them in a single 700 x30-50 mm size( but with Presta or Schrader valves ), so I can’t use them on my Urban Arrow daily driver.
Retail price is US $30/ PS23/ EUR2 5. Australian pricing is to be confirmed.
