Easily top up tubeless bicycle tires with sealant through the valve using these 3D printed funnels. No more spills or blocked syringes! I provide funnels for both Schrader and Presta valves.
Last winter I switched to using studded Schwalbe Marathon (HS 396) tires for winter commuting, and I have been wondering whether I can set them up tubeless. My reasoning is that I really don’t want to deal with a puncture in the winter. For one, road side repair is pretty much out of the question because my fingers would freeze off and the patch would probably not adhere in sub-freezing temperature. Considering that I usually dress fairly lightly when I cycle in the winter, the prospect of pushing my bike home is not very appealing.
