BD: TYRE VALVE ELBOW
I carry an elbow in my jacket pocket these days.
It saves me having to lie down on the ground to check the pressures on a lot of modern motorcycles.
With so many bikes now having 200 section rear tyres the critical task of checking the rear can involve a convoluted 'swiggle' with potentially stripped threads on valve stems. It's just hard to get the air gun inside the wheels, not to mention the seepage.
These units are $15 and in stock at motomail and save a lot of trouble.
I can also vouch that it will save you a lot of unpacking if you have it handy to show the customs guy if you are traveling by plane to a job. Show them BEFORE your kit goes through the x-ray machine.
