Cool, I'd turn the extension clamps so that they are under your arms and don't protrude.

Where are the brake levers?

Cheers

Interesting. Arm rests look really uncomfortable.

Perhaps "DIY Aero AND Die" would be a more appropriate thread title :D

Hey Jeremy,
I agree with the other poster about the armrests. I think that they might 'give way' when you need them most (putting the most pressure on them). Remember the fatigue life of Al, and that stuff looks pretty thin. Would it not be better to just get some sculpty or air hardening clay to make a mould for your forearms, then make a negative cast with something cheap like plaster, or bondo, and then make some longer length, form fitting cups with CF. This way padding needed is minimal (since it is custom to your arms), and it should provide a little more control; as it provides a positive 'locked in' feel (rather than sloshing about). Nice job on the welds, by the way...Im going to have to learn to TIG one of these days.

Yeah maybe, but the elbow platforms are steel:




And the majority of my weight is actually on the aerobar underneath, not the plate itself. As mentioned will get some 1/4" neoprene or other Cee Gee padding material to cover the bolts.

Sorry about that...I did not realize that you went steel. I once tried to make some homemade 'crampons' from stainless plate (1/8"), and was sadly disappointed by the performance. Within 100 yards the teeth were all bent and pointing in different directions. What I failed to do was introduce any stiffening channels stamped into the structure (what do you expect when all you have drill with a cutting wheel). But I digress... Nice job on your bars.

now get some sheetmetal and shape some aero fairings for the back of the 'basebar'

and shave down those extension clamps somehow!

That one should be easy...Just make sure that the extension is right, and then glue it. Get rid of the clamp all together...no reason for it.

For the fairings, get some Great Stuff and put it behind with something to shape. Cut it to shape, and slap some cheap glass on top and paint. It should also add to the 'integrity' and 'stiffness' of the structure; thus conforming to the rules.

I like it!

My only nit to pick is that I think I would have made the extensions just slightly wider apart...so they line up more with the outside of your forearms...just to get a little bit more "handgrip" separation. But, I realize that's mostly a personal preference.

Let us know how the testing goes...

The silver tubing is 25.4, I was considering using brake levers (probably cyclocross levers) and put them where the silver tube clamps are now = double duty. Brakes would then act as the tube clamps.

However, I decided that these 25.4 tube clamps + visions looked more badass. Also didn’t find 25.4 brake levers too easily.

Plus, really wanted these Hed Flip lites, but they are $200 retail and they have the same clamp issue, so figured I couldn't be that bad:

Have you considered countersinking the screws on those arm rests? (And using screws with flat tops.)

I considered it. The plate is very thin. Wouldnt be able to countersink too much. If I make a set out of carbon, I'll probably do that though.
