Airing down is now a breeze with the Indeflate by Maxtax.  No more bending over of long periods and you can inflate or deflate two tyres at the same time. 

Features: 

• Unique dump-valve mechanism that automatically equalises the pressure between the two tyres.
• 700kpa (100psi) combination pressure gauge
• Clip-on valve chucks
• A Schrader valve on one end of the dump valve (the same as the valves on your tyres) makes it easy to connect to an air-compressor to inflate your tyres simultaneously too.
• A durable carry bag
