I am rebuilding my old road bike, and I really want two things: an internal 7- or 8-speed hub, and bullhorn handlebars.
Unfortunately, over three days of searching on the web, I'm finding that there's no standard setup for having both brakes and shifters on bullhorns, and most people's solutions are jerry-rigged, one-off solutions for their particular setup.
I think I've come up with a solution that I'm happy with, but would love to hear your comments.
- Basic cheap Origin-8 bullhorns, 24mm, 20.1 mm Inner diameter
- A JTek 7- or 8-speed bar-end shifter.
- A single time-trial style brake lever for the other bullhorn, like one of these Crane Creeks for the front brake.
- One (or two?) cross levers like these Soma levers.
The idea is that, in the hands-forward position, I'd have access to the shifter and the front brake, and in the upright position I'd have access to the other (or both) of the brakes.
Mostly this is a compromise because the bar-end JTek shifter seems like it is the only shifter that would work with bullhorns and an internal hub. Since that takes up one of the holes, I can only have one other brake on the other horn. I've read about Paul's Thumbies, but as far as I can tell they wouldn't work for 7- or 8-speed internal hubs.
Also, because I'm a newbie at all this, I can't work out whether the cross brakes work as interrupter brakes -- that is, whether I'd be able to have a second lever for my front brake. Also, do interrupter levers even work on center-pull brakes?
So, any thoughts? Any better way to have both the shifter and brakes on the bullhorns? Do the components listed above all fit together?
Thanks! First time trying to do bike work at this lever, and I've been in a paralysis the past few days with all the (mostly incompatible) options, and I'm trying to finally settle on something!
(There's also a nice setup here with bar-end shifters and what look to be timetrial brake levers, but I can't find any information on what the levers are.)
