You people with your home made wheels have been an inspiration. Now I couldn’t afford a disc so I made my own. I can’t afford a new crevelo with wheel cut out so I thought could I build my own? Well I’m not that ambitious but it got me thinking and here is my question, what would happen if I coverd the whole rear triangle of the bike with this monokote stuff, what if I covered the main triangle with this stuff, would this have a positve or negative effect on aerodynamics.
You are a very knowledgable forum, as anyone got any advice before I waste some more money.
- watch where your heels go when you’re pedalling.
- do you have water bottle cages in your main triangle?
Crosswinds would probably see a higher coefficient of drag on that kind of bike. Might help if you’re only riding on the track.

You would look like a dork… 
Sorry. Couldn’t resist. We can’t all be Bunnyman.
You would definitely have handling issues in crosswinds, my friend.
the old Trimble bikes had a solid frame, basically a double diamond shape covered by carbon composite material with a solid rear triangle like you are suggesting. Seemed pretty heavy but I know a guy using one currently. I can imagine it would be a beast in crosswinds.
Thanks for your constructive reply. So that’s how we make advances, if it’s going to look stupid then don’t bother, even thought it might be faster.
I don’t see why it would be any worse in a crosswind. It would be covering a portion of the bike that allready has a disk on it plus a couple more square inches. I don’t know why people would discount a new idea based on it looking stupid. Probably nobody here has any experience with covering the rear triangle. By having the leading half of rear wheel covered may make the use of the disk not important.
I would however make sure that it is legal to race with. It may be considered a fairing which may or may not be legal. That is something for the rule experts. Maybe someone that is a referee can answer that question.
If it is legal, (or even if it isn’t) I say go ahead and try it out. Let us know how it works and send some pictures too.

Pertaining to the legality of the rear triangle coverings.
In my opinion, a P3 would fail to pass this rule so it is open to interpretation.
5.11 Bicycle Specifications.
e) There must be no protective shield, fairing, or other device on any part of the bicycle (including frame, wheels, handlebars, chain wheel, and accessories) which has the effect of reducing resistance. Aerodynamic carriers for food, water, and or cycling provisions may be attached to or be an integral part of the aero-handlebars if they meet the following guidelines:
Here is another rule that could make it legal.
5.12 Untraditional or Unusual Bicycle Equipment.
Any unusual bicycle construction or equipment to which the specifications in Section 5.11 cannot easily be applied shall be illegal unless prior approval is received from the Head Referee before the equipment is used in the event. Any violation of this Section shall result in disqualification.
