Bullhorn Handlebars(2 posts)

I find that I rarely ride my bike with my hands down in the drops. I rarely see anyone riding in the drops for that matter. I find riding on the hoods to be somewhat uncomfortable since there really isn't a flat section that fits your hand. I was considering switching to a bullhorn handlebar. I'm not a racer, so UCI rules don't matter. I'm not into triathalons or time trials so I don't want an aero bar. I was just going to use my regular Dura-Ace STI levers. I was wondering if anyone else has tried this set-up and if there is anything I need to consider before trying this.

It will work fine, I've seen people do it. In fact, I will do it as soon as I get the cash for some new bars. Here are 3 things to consider:

1. I *think* bullhorns of a given width require a slightly longer brake cable and a slightly shorter shifter cable than a dropbar of the same width. (I think, others can correct me if I'm wrong). At least it seems that way logically.

If you envision the cable path on a bullhorn, the brake cable has to basically travel to the end of what would be the tip of the hoods on a drop-bar, and then has to hook downward. On a drop-bar, the brake cable would stop a little before the tip of the hoods. If your brake cables are tight it *might* be a problem.

2. That also brings up the second issue. If you want the brake cable to wrap under the handlebar tape, you have to make a REAL SHARP bend in the cable at the tip of the bullhorn, right after the cable leaves the lever. That's because with the levers hanging under the bars, the brake cable would naturally leave the lever at a upward/ forward direction. (I have installed aero brakes on a set of bullhorns). In theory this can cause swishy braking. Whether or not you will notice this is another issue.

Some people fix this by letting the cables swing out into the open air, ala non-aero brake-lever style. I think that's ugly, so I go with the sharp bend in the cable.

3. Also something to consider: Bullhorns come with varying drop. You may want to get a pair with some drop. Because you will be losing the option of the drops position, you may want to find a position on the bullhorns that is in between what you would have with the hoods and the drops. Remember you can always ride the flat of the bar next to the stem If you want a more upright position.

Even if all you want to do is imitate your hoods position on the drop-bars, you still want to get a *slight* drop in your bullhorns. That's because the hoods on a pair of drop-bars in slightly lower than the stem clamp. If you get a pair of bullhorns without any drop, it will raise your position.

Sorry that turned out to be a long post.
