Everyone can point and laugh because I personally still have plenty of weight to loose. But I wanted a second wheel for dedicated trainer use, so I was in the market for something. I ended up demoting my current wheels for the trainer use and got some take offs from the top of the line allez to use as my normal wheels. Compared to my stock setup these are the cost and weight savings.

The big weight savings for me was the conti tires versus the stock ones, cost $65.
310 grams each stock to 205.... saved 210 grams
Then I got ultralight tubes, $20
119 grams each stock to 55 each... saved 128 grams
Decided to go with velo plugs instead of rim tape, $13
19 grams each strip to 5 grams per wheel... saved 28 grams
Then picked up a dura-ace cassette off ebay for dirt cheap, $45
270 grams stock to 170 grams.... saved 100 grams.

466 grams savings in for a total of $143.

I could have gotten them set for half the money with no weight savings, but I figured why not try and make them lighter?
