Nextie 36" carbon rim

How did you manage getting the stretched inner tube on?

It’s my first 36" so I never done it before but it was suprisingly easy (or maybe I got lucky… )

I just inflated it lightly to get it into shape. Just as I would do with a regular tire/tube change.
Then I put the valve through the rim and then I slowly stretched the tube around the rim. Afterwards I carefully made sure that the tube was not twisted anywhere. While slowly rotating the wheel I lifted the tube a bit off the rim to make sure it was as evenly stretched as possible. Last step was obviously to mount the tire itself without pinching the tube.

The reason why I chose this tube is the post quoted below (SV19/AV19 is likely the same except for the valve). He also shares some interesting other points about mounting and using stretched tubes.

I’ve been running Schwalbe AV19 29er tubes in my Airfoil KH36 single speed for 4 years now, several centuries and thousands of miles now and I have found a couple of things that make the 29er tube work well for me. I’ve installed several of these for friends too using this technique:

Only negative I have to say about my configuration is that a valve length of 40mm is a bit short for the Nextie rim. Look closely at the pictures and its quite obvious. If you are unlucky your pump might not be able to get a proper connection to the valve.
