More on weight lossZip-a-Long

Well, the Mavics have held up well with their reduced spoke count. Rode about 75 miles (2 rides) over the weekend, and they held up well. In fact, I have managed to true them a little better, so that they are almost perfect now. I was tempted to reduce the drive-side count as well, but thought that with the power that side, it might just cause torque problems, which would be tedious from a truing point of view.

While I was at it, I took out all that pointless rim-tape - you only need the bits over the spoke holes - I really don't know why they put the rest in there. Does anyone do a "ladder" shaped tape, with material only where you need it over the holes?

Anyway, it's a real nice feeling knowing that you are riding on wheels that are actually based on what you need, not the need to be litigation proof for some 250lb clydesdale.

Anyone got any suggestions for how one can determine the number of spokes you actually need on a given rim (other than by riding to failure).

Anyone know where one can buy hoops that you can drill out yourself, rather than being stuck with the number of holes already in the rim from the factory?

While you are at it, don't forget to drill out your frame. It was also probably overbuilt to the litigation proof standards as your wheels. If you put the holes right, you will perform better in cross-winds, which is the down side of most wheels. Then with your lighter wheels and drilled out cross-wind friendly frame, you could win the Tour next year! Think about it, even Armstrong, with that cool John Cobb fork doesn't have a drilled out cross-wind friendly frame!

Get real. If you are looking for super lightweight, why would you do anything with cosmic elites. They are tanks to begin with. Why not just build up a King or Hugi hub with a 28 hole rim and revolution spokes. If the weight you saved taking out spokes is such a big deal in your performance, why not look at relevant weight loss in a wheel. Use alloy nipples instead of brass, get a lighter tire/tube, and for god sakes don't use an aero profile rim that weighs a ton. Rotational weight is the key to fast wheels. The spokes you took out have much less effect on rotational weight than a tire or rim. The moment of a spoke starts at the center of the wheel and goes to the rim. That makes the few grams spread out over the distance of the spoke. Weight on the rim and nipples is at the far extreme end of the radius and have a greater impact on the rotational moment. All you have done is make your wheel flexier and increased the chance of hub flange failure from empty spoke holes. Good luck.

PS Please don't ride these wheels in group rides. It wouldn't be fare to take someone else down with your moronic mods.

how about just training harder and eating better. and buy some pro jerseys, after all, if you don't look good how can you go fast?
I second that ... PLEASE NEVER Ride them on a group rideInTheMiddle

If you want to crash yourself go for it... but as spookyload said, please be responsible and respect the fact that others may be impacted by your experiments.

Even non-modified parts fail at times... don't be stupid and help them along !

I guess that proves the durability of this approach. As suggested by others, start drilling out your frame ASAP. I bet it'll last 1000 miles! Why, that's virtually forever!

I seem to recall someone mentioning a study proving that the tire bead is not really what holds the tire on. Perhaps some more weight could be saved by strategically removing unnecessary sections of that. While we're at it, you know, a front tire lasts just about forever, and that means you don't really need all that rubber. you can save a few grams at the important outermost edge by using a well-worn rear tire up there. Perhaps you could send him one from your large collection.
Careful...someone may not see the sacasm in that postFez

and might actually take a new tire, remove some excess rubber and actually ride it.

all across the board.

Thanks for all the really helpful, intelligent, thoughtful comments, they really are most helpful.

I have learned just HOW HEAVY my mavics are, which I hadn't noticed - thanks for the illumination. Can you believe that shipowners haven't brought them all up by now - they must be much cheaper than anchors, and just as effective.

Thanks also for all those people who are terrified to think even a micron outside the box - that should surely ensure that progress is nice and slow.

But most of all, thanks for your sevices to the keyboard indrusty. It's folk like you that have absolutley nothing to contribute, but still bash away keystroke after keystroke, unable to contain your "holier than thou" criticism back that are holding those guys together out there - special respect to you.
how's this for outside the box?Damn

Why don't you remove your saddle and just poke a hole in a tennis ball and put it over your seat post? That way you can remove the saddle clamp and bolt too.
Do you really need a front brake? I thought not.
With training you won't need the tennis ball either! [nm]niteschaos

And it's not pretty. The "box" is reasonably well defined and it's pretty obvious what happens when you step outside it. You can defend this sort of foolishness all you want, but it really doesn't deserve the protection. After over 100 years of the evolution of bike parts, the "don't go there" places are pretty well known, but people just can't resist returning for a visit, hoping it will turn out better than the last time.

...not sure of the molecular weight savings but after the big win you could take a big "drag" off of the tire and sound like a "munchkin" on the podium. We represent the Lollipop Guild....etc...

Whoa...it could work...now...down to the laboratory...walk this way....

Drilled out parts = BAD, I watched a guy eat it on a descent (mountain biking) and wake up three fours later in the ICU. He hasn't riden since. On a second note: one year Telecom ran nitrogen in their tires during the tour, I wonder if it helped? And why nitrogen?
