This bar, "Casey's Chromoly Crazy Bar" has been absolutely amazing on my bike (see my signature):
Casey's Chromoly Crazy Bar, Noir
I've used a flat bar w/'bull-horns' and most recently a "trekking" (aka 'butterfly') bar, but neither have come close to my Casey's Chromoly Crazy bar. I've been using the trekking/butterfly bars for a couple years now and they have been great - they were a definite improvement over the flat bar w/bull-horns.
However, my new Casey's Chromoly Crazy bar has proven to be a
huge improvement. The very comfortable (natural-feeling) grip section works very well with my commuting ride and i really like the "aero"/bull-horns (?) which allow me to stretch out on long, straight sections. I also like the junction of the "aero"/bull-horns with the main bar because it provides another "natural-feeling" placement and i find myself resting there the most.
Installing the Casey's Chromoly Crazy bar did require me to use a quill-stem adapter which added some cost, but overall the whole project was less than the Jones H-bar alone which i also strongly considered.
I was initially hesitant about the Casey's Chromoly Crazy bar because none of my local bike shops stocked it (or had even heard of it!). In fact, there are not many here who have used/tried/heard of it. But, for me, it has been a great decision and i'm loving 'em!!!
No, i don't work for Velo-Orange - i'm just very pleased with the product and hope others can experience the same enjoyment with them that I am.
