Great product, fast shipping.

The website was easy to navigate and the color selection for the products made it easy to customize my project. Great work!


So I had other bullhorn bars, and thought these ones were going to be pretty much the same, but I feel like these ones are perfect for me. The minor size differences made a huge difference for my comfort and I love them! Great bars


Bars were easy to install and now my single speed pigeon is more comfortable on the longer rides.

Bullhorn bars

Absolutely worth the purchase. With just a single gear there are times when you really need to get after it. This style of bar allows you to get in a better position to really "crank" on your pedals.

Just what I needed

I ride the 6061 Black Label and was using the aggressive pista bars for a few months but decided to go ahead and purchase bullhorns as well for different terrain I come across during travels. They're a good diameter and shape and get the job done, no complaints. At a reasonable price and supporting the same company for components like this, you can't go wrong.


Super nice experience, you have a very good service and you deliver quickly. I am super happy with my purchase and I continue to see your products. Merci Beaucoup guyz ! Carlos Vargas from Montréal Qc. Canada

Great for climbing hills

Bought silver bullhorns for my State 4130 Core Line Matte Black 4. I've logged about 300 miles on it and have had zero problems. Their construction has been sturdy enough to not flex when I'm climbing hills while gripping the bar ends.
