Converting from drop bars to bullhorns with bar end shifters?

I hate drop bars! Hate; hate; hate! But I love my Shimano Ultegra gearset. I had a bike with bullhorns before, but the shifters were friction, and set next to the stem. I want my brakes and shifters at my finger tips. The only compatible equipment I've found are these Dura Ace 10speed bar end shifters; but I haven't found any example of someone actually using them on regular bullhorns, instead of a triathlon setup. I can't be the only one. I'd love to hear about anyone who might have successfully done a conversion.

There are bars that regular dropbar Brifters will fit on. Hte Brifter sits flatter like an MTB brake but the actuating of the paddles might take some getting used to.

I've tried that. While it looks promising, I've never been happy with the result. On the bars I've tried, the brake lever doesn't get enough stroke before bottoming out against the bar. Maybe if you do a flip & chop. Or is willing to tolerate a high maintenance / low clearance system. Or a deliberate mismatch like v-brake levers and caliper brakes.
Then there are cables. On brifters cables expect to exit back-and-up. When sitting underneath a bullhorn they need to go back-and-down - if you want the cables under the bar tape. And that often results in high friction. More doable on the older types of Shimano brifters where the shift cables run exposed.

Have you considered putting interrupter/cyclo-cross levers on the straight sections of your dropbar?

Cheers

Fit the bullhorns, then fit the STIs so they are facing down, and the levers are under the bars. I set up a pair of bullhorns like that with road brake levers on my fixed gear originally, and actually, they were very comfortable and importantly the levers were very accessible. If you get the right bars with an upturn at the ends, you should be able to adjust the position of the levers so you still have plenty of pull for the brakes and no intereference with the shift levers.

It's not the drop bars I hate- but the positioning of the brake levers with the normal "brifter" setup. Therefore I convert everything to bullhorns.


For shifters it's DA bar ends. Brake levers are cross type (interrupters). This levers allow one to run the brake cable rearward to follow the shape of the bars. I've also used this same "cross lever" for linear pull (v-brake) and road calipers. Plenty of travel for both, and good power and feel for either. I run both brake and shifter cables under the wrap to exit near the stem.


I'm probably at 20 or so like conversions and couldn't be happier with shift and braking performance. It is flawless.

TRi bikes is why they Make them .. Racing. all other uses are trickle down.

I couldn't stand Bull Horns withut the Tri Bar and elbow pads

but that was 20 years ago..

Now Im Using Trekking Butterfly Bars .. you would use a thumb shifter conversion there ..

the guts of your bar end shifters and these : https://paulcomp.com/shop/components/thumbies/

let you use them on other bar types.

You could mount your bar end mechanisms on these and adjust the shifter angle to suit:

Sounds good. I've never ridden a bullhorn bar but I liked the idea since I rarely ride in the drops. I was going to flop and chop but read that bar ends usually won't work since they need a straight section. I have DA bar end shifters. I was going to build a bike up for duathlon racing (I'm no serious racer, but just to have some fun) with aero bars, but after trying out clip on bars I'm not sure I really like the handling plus it's added weight when I am trying to make the rig as light as possible.

I guess I say all that to ask a question... if instead of using aero bars if I just used a bullhorn with bar end shifters, are there levers that will work that still place the brake lever on the end of the bullhorn instead of back towards the center. And have the cable coming out properly run under the tape? It would be nice to have everything on the horns of the bullhorn imo. Does anything exist to do this with?

I've used interrupter levers on a couple of bullhorn builds with great success. I incorporated them with a bar end shifter for a 3 speed Sturmey Archer on my Nishiki.
Here is a short video demonstrating how I did it.

there are parts made for Tri-Race Bikes to do that too..

proper reverse levers & downtube shift levers on the side

I already have bar end Dura Ace shifters though, I am wondering if they have any reverse brake levers that bolt around the tube and not into the bar end. Well I have "proper reverse levers" too, so I guess I could go either way. But bar end shifters would look a lot nicer than mounted on the side... and brake levers that clamp around the tube is a pretty normal look as well. With the vast selection of reverse brake levers I can't believe there isn't a single one that is clamp vs inside the tube end, ah well.

Dan - I'll check out the video sometime at home. Youtube is blocked here at work.

Oh I see what you did there now Dan... the cable is installed 'backwards' (?) to get it in the other direction, I didn't know that could be done that way. And I didn't think of the interference between the two, and routing the cables. I might have some issues there with the bullhorn bar I have, I don't think there are grooves like that in mine.

My bar isn't grooved either, the cables sit outside.
For a 3 speed, having the shifter backwards like that works fine, not sure how convenient it would be for a 10 speed derailleur system.
I had to do it that way to get the cables to play nice together.

Could you post a photo or two of your example? That would help me a lot.
