Bullhorn w/internal routing

Hi all, just wondering if anyone knows of any good options for an internal routed bullhorn bar? I'm putting a retro TT machine together and was thinking of just getting some Nitto bars, but internal looks so much better...

Depend on clamp.

If 31mm can run Deda Chrononero lowriders.

Do Mavic do internal retro bulls?

internal routed bullhorn bar... ...retro

?

erm..drill?

See exhibit '3TTT Moscow', but my idea of a bullhorn, at least in this case, is a cut down Cinelli 64/66. Unfortunately I'm not prepared to risk drilling them, otherwise this would be very easy to solve...

Buy 66s. Fit brake. Cut. Work out where holes should go. Drill guide holes. Enlarge said holes with larger bits. File edges of holes to allow the cables to exit at an angle.

I am the second worst mechanic on the planet and did this at least three times in the 80s.

I am (probably) not dead.

?

Is this retro?

Nope, modern to old twats like me and I have a shoddily drilled pair of those knocking around somewhere (not my work), I rode them for a couple of seasons and am still not deceased.

I have some Cinelli Tempos for sale, factory drilled.

I had a pair of no-brand bullhorns that came drilled for a brake, with a little guide too, had to spend some time filing the crap out of it until it was actually big enough to fit a cable outer through, bar wasn't reinforced in any way where it was drilled, pretty sure if you buy some bars you like and drill'em you'll live to tell the tale

I think I may just take you up on that...

I know I possibly am being over cautious with the drilling, but I am the worst mechanic on the planet.
