Revolutionary. If we have a household.
"Like the brand's other chambers, for tubolitos to perform at their best, a number of parameters must be met. 1. A super-clean tubeless-ready rim. 2. A super-clean internal tire. The slightest 0.1 mm² chip and you're guaranteed a puncture. 3. Avoid extreme chamber tolerance. Here, 47 mm. If you respect all that, no problem (for me, anyway). 600 km of gravel, on rather rough tracks in the Pyrenees, at 1. 5 pressure, no puncture to be deplored. (Probikeshop made a mistake in the description, these go up to 47 mm. )"
