The Schwalbe SOS Pump is a small, handy, and enormously stable emergency pump, perfect for the road. It measures only 12.9cm long, fitting easily into a jersey pocket or attaching directly to your bike frame. This pump is also suitable for tubeless tyre inflation and includes a frame holder. A smart feature is the lockable pump handle by rotation, which clamps directly to the valve without screwing, preventing abrasion and ensuring an airtight seal. An additional seal protects the pump from dirt. The pump has an anodized finish.
