Actually there are frame designs that do not require the chain/belt to go through the triangle. The current Gravity FSX. or don't have a triangle. Like the old Trek 9000, or the 94 San Andreas.

But those frames with rear suspension present a different problem and that would be keeping the belt tensioned. The new trek belt drive bike has a tensioner but I think that's intended for a wheel that stays in the same place.

The point being, you could design a non suspension triangle the shape of the FSX and you wouldn't need a break or have a removable part in the triangle. For that matter it would be totally feasible to use a single side rear end much like BMW motorcycles.

In the wind
I borrowed my friends trek soho for a week to try out the belt drive/igh thing and loved it. Very nice and low maintenance, a big plus for winter commuting.
My only dislike is the difficulty in rear wheel removal. I think fixing a rear flat would probably be easier to just patch it in place.

Sure. But the post I was replying to asked about retrofitting a belt drive to an old bike. At first glance nothing looks particularly special about the frames used on belt drive bikes, but of course there is a key difference.

I have a belt drive with a Rohloff hub. It's not any harder to remove the rear wheel to fix a flat. It's easier than some derailleurs with a strong spring (and no grease).

This odd example doesn't have any left-side stays, but no reason it couldn't.

Genetics have failed me
Same here. I also have a Rohloff with gates belt drive and disc brakes. Popping out the rear wheel is no different and definitely less messy then my other bikes with rear derailleur and dirty chains.

My Harley has rear suspension,and the belt doesn't need a tensioner. In fact,none of the belt or chain driven motorcycles have tensioners(or derailleurs). The suspension's movement arc is just taken into consideration when it's being designed to maintain drive tension.
