For Zipp 900 clincher owners who are fed up with the tiny valve opening and limited inflation option

My Saturday morning project.

Had to do a similar hole expansion to get my old 404 disc wheel cover to go over my Edge 65 w G3 power tap. The drive side fit perfectly, but the center of the non drive side did not have a large enough diameter to go over the G3. About 15 mins of careful work did the trick.

Nice work... I got rid of my 900 clincher because of the stupid hole that was too small and to close to the rim.

Man that is very cool. I am utterly paranoid of all the strange forces placed on the valve when trying to get the crack pipe on and off in such a small space. I'm going to do that surgery for sure. Awesome!!

Why Zipp designed the wheel that way is perplexing.  There's no effective way to use a tube that's not 30mm (which you'll never find, especially in latex).

 

I almost want to fly up to Zipp's HQ in Indianapolis, find some of their engineers and punch 'em in the nuts and shout "You Know Why!!!"

At Bob. ... Too funny! I usually feel that way about Microsoft software, but this fits the bill too.
