The joy of building you own wheels. No project is too ridiculous! Wheel recycling.
 
Due to the cold weather even here in Houston last week I was riding my Giant carbon bike on my trainer when I noticed the tires were really worn and ready to be replaced. Normally that's no issue, but if I do that I will have three bikes with essentially new tires on them. I don't want to use new tires on the trainer, but won't have a choice. I have three pairs of wheels right now, but all are installed on bikes. No extras (in a manner of speaking).

What I do have though is a pile of ka-ka wheel parts. Well actually it is all really fine stuff, but it is just gathering dust. I have a nearly new pair of GP 4000Ss I have been saving since I sold the wheels they were on. So that takes care of the wheels for riding on the road.

I have had a Kinlin XR-200 32 hole rim listed on ebay for about a month with nary a nibble. So as soon as I got off the trainer, I ended the ebay listing. Then I searched the internet for a cheap rear hub. Found a Tiagra 4600 for $31 delivered (Amazon Prime 2-day no less). Next I dug through my hundred or so "spare" DT Revolution spokes for the needed sizes. The requirement was for 16-289 mm and 16-290 mm spokes. The largest I have is a bunch of 286s and 287s. No problem. I checked on the recent poster on the 41 who said that longer nipples don't allow one to use shorter spokes, and found he was wrong as far as DT 14 mm and 16 mm nipples are concerned. Tah dah! The DT 16 mm nipples take spokes about 3 mm shorter than the 12 mm nipples. I found the required nipples on a half-price sale for $0.15 each at Cambria. Unfortunately the shipping cost as much as the nipples, but for $12 altogether I got what I needed. A used Ritchey yellow rim tape is also waiting patiently in my junk bin to be installed. And lest I forget, I saved an old SRAM Red cassette that a new chain was skipping on in my most frequently used gears. Funny thing is I can use it on the trainer wheel without a problem, because I only ride the three or four largest cogs on the trainer due to the high resistance of the Nashbar fluid model I have. They are like new, having been hardly used at all on the road.

$43 new expense all in. I know it is easy to find serviceable wheels that cheap or cheaper at places like Nashbar, but what fun is that? It's like butchering a hog: nothing is wasted.

A couple hours after the missing parts arrive I will have my spare rear wheel to mount one of the nearly used up tires on. And I will have gotten rid of a lot of stuff I didn't know what to do with. I will also permanently install the heavy-duty trainer-specific skewer and not have to go back and forth between it and my regular road skewer any more. Cycling is a great sport, but I have to say it may be an even better hobby.

While everything goes together the nipples don't survive because they don't have good fatigue life when loaded in tension.

You'd have done better shopping around for correct length $0.40 spokes and using the included 12mm brass nipples.

You mean the longer nipple isn't reinforced by the spoke tip extending into the area above the nipple shoulder? Yeah, I know about that. It will be intersting to see how close to the driver slot I actually get when I finish tensioning. I may well get into the nipple tops. And I'm using brass not aluminum. But thanks for the input. It is a good point. For trainer service I am not too concerned that a nipple may break down the line.

Just to bring some closure to this thread, here are photos of my "new" dedicated trainer wheel. Pretty good for $43 new money out of pocket all inclusive. I am really impressed by the Tiagra hub. I think it is gorgeous. Heavy as lead (358g) but very nice looking. I usually use 220 g hubs. But the extra weight is really a plus on the trainer as it provides a little extra flywheel effect to smooth out the pedaling. Very little I guess, but something. Built like a tank. And smooth rolling too after a very slight adjustment. This is going to work out really well.

2 questions:

Did you put a new tire on your trainer wheel?

Can you really feel and extra 140 grams rotating at a radius of 1"?

No and NO! That is the old tire I had on the bike I was using on the trainer. Put new ones on the bike and moved one of the old ones to the spare wheel. I didn't want to put new tires on the bike while I was using the main rear wheel for the trainer. Now I can use the new tires on the road and the old one on the trainer.

As far as the weight is concerned, it is just about keeping score. Once a weenie, always a weenie! No, the idea that the extra weight could help is as silly as it could hurt. But I never forget that you don't get to a really light bike (I'm talking out on the road now) by giving up 140 g here and 140 g there. Kind of like they say about money: "A billion dollars here and a billion dollars there. Pretty soon you are talking about REAL money." Same thing with bikes, before long you CAN feel it. Anyway it is all hobby s$*t. Just for grins. :)
