There is. I am anxious to give them a try, but as of now, the roads are just crappy enough to keep the trainers on. Air Brakes are installed, and they get a ride today.

Have a good ride.

I was referring to the valve stem knocking on the valve hole on the rim issue. It's annoying as all get out.

I guess I will remain one of the few who use the retainer nuts. :)

I'll pretend I didn't just hear that.

In addition to violating the terms and conditions of the 41, it also violates the actual rules. THE ACTUAL DAMN RULES.

On carbon rims simply cut a short piece of electrical tape, cut a small slit in it for the valve. Place the tape over the valve and onto the rim. Annoying 'knocking' sound gone.

This method may cause Bdop to continue drinking the cheap local brews rather than the expensive imports he so richly deserves.

Thanks. It was great, and the Air Brakes were awesome. Highly suggested.

I was also referring to your Valvinators as far as the knocking goes. As stated, the roads are just crappy enough to run the trainers, and not the deep sections.

To be honest, my first attempt to eliminate the knock was to cut a piece of drinking straw and slide it over the valve stem and into the rim. It worked pretty well but they would fall out from time to time so after a while I sought another solution.

here's an idea from those inventive Spaniards;

My Vittoria latex tubes came with a clear plastic sleeve over the valve stem - the same concept as Bdop had with the drinking straw. They fit pretty tight and don't slide off on their own. I like them.

Yep. I don't give a F. :thumb:

I leave them both on, the weight difference isn't big enough to matter.

The whole world is going to hell in a hand basket, and we got anarchists here in the 41. For shame sir.

I used the nuts on my box section rims, makes it easier to get the pump head fully on (or at least to be confident that I have done so). I got some RS80's when I killed my Mavic Cosmos, and the nuts don't sit properly against the rim. I do use the caps. The couple of grams is worth the insurance against the (small, but has happened) chance of bending the end of the valve stem. I also use a seat bag and carry a frame pump, so I guess I agree with Patrick above about the rules!

For a cheap solution to that ^^^ you can go to the hardware store and pick up heat shrink and your wife's blow dryer. That should last a long time and very easy to install.

The problem is when you flat and have to change the tube. It is a quick fix but not a permanent one.
