"Multi Tool3-8mm hex keys, Torx T25, screwdriver and valve tool""
Why does Schwalbe offer a multi tool? Because we wanted to have a handy tool 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 need to take out or tighten a valve insert.
