The Jam.

Mini pumps are great for fixing flats in the field but we have seen (and experienced) many-a-damaged valve from the leverage of herky-jerky motions during operation with the bike precariously on its side. Blackburn's Core Slim Mini-Pump has a pull-out hose that puts less stress on the valve. This slimmer version of the Core Pump features a thread-on Presta-only specific head and the short pull-out hose provides an effective damper between your pumping motion and the valve so you are way, way less likely to damage it. The pump includes a machined valve core tool right in the pump's base so if you need to add tubeless sealant or tighten a core, you can easily do so. Also included is a frame mount that puts the pump right under your water bottle cage so you can easily tote it around.

  • A mini pump with a hose to get you going after a flat
  • Includes cage mount hardware to hang on your frame
  • Pump head threads on to presta valves only for a sure connection
