Biologic just announced a new gadget – the Postpump 2.0. Yep, a seatpost and a tire pump, together as one, compatible with both Presta and Schrader.
While serving normally as a standard seatpost, when running low on air you can pop a pump and stainless steel footstand from the bottom. Biologic designed the Postpump 2.0 for Tern folding bikes, but it fits many others with a clamp diameter of 33.9mm and 580mm height. Total weight is 718g. MSRP is $50 and it’s sold in black and chrome.

For tiny 20″ x 1.5″ tires, Biologic estimates it takes 40 strokes to pump to 50psi.
