Everyone should have one of these to carry on their bike. This extension hose will allow you to put air in your tires no matter what kind of air chuck you run across on the open road. I keep one under the seat so I always have it with me. This hose and short rubber valve stems are all you need.

Or, you could replace your stubby and annoyingly hard to reach OEM rubber stems with the easily reached 90 degree steel ones I posted 2 years ago, and not have to carry around any just-in-case band-aid solution to a problem that shouldn't exist in the first place. Unlike your statement when we were discussing this years ago, you have nothing to lose, and much to gain. To wit, I used that exact part you listed there because I couldn't reach the stock stems with any of the chucks I owned. About 6 months in, I went to use it while on a ride in VA and it had developed a leak at the hose/fitting juncture. Luckily it was a small leak, so I was still able to re-inflate my tire.
To be clear, I have no problems with the short rubber stems in principle. The problem is that they are very hard to reach in this particular application. In fact, in over 30 years of riding it never even occurred to me to try any valve stem alternatives; I mean, why bother? But on the Tenere, it's an imperative IMO.
These stems will last forever, fit fine with no alteration of any kind, can easily withstand the extra weight of TPMS caps should you so-desire, and are easily reachable with no added attachments or specific chucks.
