Re: "I build me a disc" DIY Aero Wheel [Rambler]
The wheel I started with is reasonably light, made by XERO. Might be cheap Alum never did brake that well actually. The front of the set was wrecked in a crash. So good to experiment with. I have been wanting a clincher disc, and the older used HEDs looked really heavy/funky.

I used a tubie tire and some clear poly. I had to use 2 full cans. As the foam setup I removed the poly - it will expand and cure better with air both sides.

Foam $15
Spackle $10
Carbon Wrap $60
I bought a 1/3 sheet sander too

The problem with the foam work is that it is not deterministic. It's up to the PU foam gods as to how it turns out. The featherweight spackle is trick from the model airplane wing guys, and saved the project. Lightweight spackle is a latex based, with super light filler, so easy to work with and sand etc. Even so the spackle added 150-200 g's straight up! I had to use the whole tub, and it was a good sized tub.

I have to weigh the whole deal now, with tire, etc.

HED Jet 9 clincher all in is 1550 gms * story about this wheelset.
Zipp Tubie 900 Disc all in is 1500
Gipemme (sp?) Aero/Deep Alum wheel 1750 gms
Shimano C50 Tubular - will be lightest of the lot.

The HED wheelset/disc combo is actually for the GURU build, still in the works. I got these baby blue Michlens on special, and that rear tire is painted :O - paint color is perfect, but adhesion didn't work!!

Edit - I rode it like 500meters last night, it makes the WHOMP WHOMP sound 100% just like the Zipp. Will give it a shakedown today - in the rain
