Multi tool with valve functions. Is it necessary? Multi tools are available ten to the dozen. Why then must Schwalbe offer such a thing? Because we wanted to have a handy tool in the pocket that integrates the functions for valve inserts (SV and AV) and valve extensions. Especially in times of tubeless, puncture protection liquids and screw on air pumps there is more and more of a need to take out or tighten a valve insert.
3, 4, 5, 6, 8 mm hex T25 Torx, slotted screwdriver, SV valve insert, valve extension SV, AV valve core.
