The original Casey's Crazy Bars in alloy are a fantastic option for cyclo-tourists, gravel grinders (a tired descriptor in my opinion), and city riders - positions galore, wide comfortable sweeps, 22.2 and 23.8 for mountain and road components, lightweight, and 'out there' good looks. Since we got the first handmade sample, we have been working on a MTB approved version. We have gone back and forth with our manufacturing engineers and tested a lot of designs using software, good 'ol thrash and bash, and official fatigue/stress tests in a lab.
As I've stated in a recent post, "We need to strike a delicate balance between intended use, timeless styling, functionality, affordability, and pushing the envelope." This product is no different. In designing the MTB version of the alloy bar there are parameters (sweep, length, position placements, various diameters) that have to stay the same as the alloy version, otherwise it's a totally different bar. We tried a variety of aluminum alloys and each had their own drawbacks: stress concentrations, thickness constraints, cost for the consumer, etc... We decided to go back to basics. This bar has to stand up to mountain riding (full squish, hardtail, rigid), loaded offroad touring, long time in and out of the saddle, fat bikes, bikepackers, adverse conditions, and all the while looking good.
We resolved to go with a plain gauge chromoly tubing. Simple, efficient, affordable, easily manufactured, and extremely durable with a very long life. We could have gone with titanium ($$!), but the bar would have been significantly more expensive to produce and personally, I'd rather have a heavier wallet than a slightly lighter bar. We could have gone with carbon, but I'd rather not worry about my bars breaking if my bike falls over.
So to summarize...steel good.
Chromoly Casey's Crazy Bars are now available on the webstore. They have the same sweep, angles, and extensions as their alloy counterparts. They weigh 860g and are MTB approved.
