Breezer style dropouts?

What are your opinions on breezer style dropouts? I am looking to use them on a wooden bike build because of the good surface area for bonding. Is there any reason I should NOT use this style droupout. Yes I know that I cannot hook up a trailer to breezer dropouts (I have no intention of hauling along a trailer in a road race) and I have a Scott AFD Pro (with breezer dropouts) and I CAN use it on a trainer - with the right skewer. So let me know your opinion on breezer dropouts - refraining from repeating the above limitations.

BTW I am not using bamboo - solid wood.

Cheers!

you will have a butt joint bond in tension, which is not good. You want to arrange for your bonds to be in shear, with enough surface area to withstand the loads.

I use them on steel frames because it allows flexibility in angles, and I think they look cool.

On a wooden bike...? As Unterhausen pointed out- joining might be an issue. If you just "glue" them on to the end of the stays- I don't want to take the first ride.

I can think of a couple ways to join them to wood- one would be to weld stubs to the hood and insert them into bores in the end of the stays. Splitting of the wood might be an issue. Another way might be to have the seat and chainstays in a continuous loop, and counter-bore the sides of the stays and insert the dropouts. Be a little tough to remove the wheel though?

I think I'd prefer a flat plate dropout bolted in sheer to the sides of the stays.

Should be shear- not "sheer." You can see right through this.

True, thanks for pointing that out. I'll probably end up just using normal dropouts glued to be in shear. I'll post some picks of the frame when I'm finished.

Cheers!
