Schwalbe SV18 Inner Tube
Best lightweight tube for road cyclists using deep-section aero rims.
These tubes are built for riders who prioritize weight savings and rotational efficiency on the road. The extra-light construction noticeably improves acceleration, though you sacrifice a bit of puncture resistance compared to heavier, standard options. The long valve stem is a thoughtful touch for deep-section aero rims.
