Bullhorns and hydraulic brakes

I'm very tempted by a Charge Mixer - it's a sort of retro/hightech alleycat racer type of a bike, with 700c wheels on a Tange Prestige frame, hydraulic brakes and Alfine internal hub. For anyone who's interested it looks like this -



- which would be a pretty good reason to buy it even without the positive reviews and word of mouth. Eg http://www.bikeradar.com/beginners/g...mixer-08-28772

However, I think that I might want to convert the bike to a bullhorn if it's possible to do so. I suspect that the only way I can do this is to keep the current levers and find a set of bullhorns that will take them, with or without shimming. Comments, better ways, potential issues?

AFAIK you can't use those levers on bullhorns, and also you can't get hydraulic levers for bullhorns.

What I would do is use some MTB bar ends, like these:


They come in a variety of shapes and sizes for you

Why not? Just bar size?

It's the obvious very poor second best, yes.* The point of hydro disc brakes is fast braking. I want to have that instantly available from my main riding position.

* I hope that doesn't sound snarky - I appreciate the answer!

That, and also they are different curves, the bullhorn/road levers curve inwards, so they can be used from the bullhorns, whereas the flat bar levers are curved outward, so they don't hit the bar when braking

Yes. But diameters can often be matched with a shim, and there are bullhorn-ish TT bars that *are* flat, eg



- although I'm not sure that bullhorn is the right name for these. What really scares me is the thought of a hydraulic problem because of the changed angle...

Unfortunately, you can't shim a 22.2mm lever (MTB standard) to a 23.8mm bar (road standard).

Which leaves the alternative of cutting away the clamp and relying on two ton epoxy. So I'm into at least moderate hassle here! Otoh, 2TE is probably stronger than virtually any handlebar tubing.
