Not fragility. Roadbikeaction said http://www.roadbikeaction.com/Bike-Test ... light.html
" onclick="window.open(this.href);return false;" onclick="window.open(this.href);return false;" onclick="window.open(this.href);return false;, "While the Ultralight was at ease on the climbs, its minimal mass didn’t necessarily lend itself to fearless descending. Paying a little extra attention on descents was necessary since it’s quicker to be thrown off its line than a bike with more mass. This isn’t a geometry or design problem; it’s merely the inevitable trade-off that the new super-lightweight bikes have to make."
I think this is bullshit.
Firstly, the BH tested wasn't "that" light. I had the same bike on test.
They had 13.6. Slap on pedals and cages and you're 14-14.5.
I think jumping to a 9 pound bike is a reach relative to the topic (and or 99% of readers)
Handling is far more about geometry, frame flex, wheel flex, fork flex, to some degree wheel weight and tire pressure in most cases.
Saying its "quicker to be thrown off line" is an overreach in most reasonable cases... Quicker to get off line than a slacked out angled 22 pound bike with 36/36 spoke, 1800 gram wheels maybe... But that doesn't mean that this bike is quick to get off line relative to the vast majority of similar bikes within a pound or 2 or 3.
The BH in the form tested is very simply NOT a bike so light that it lacks control.
I rode that bike with MADfibers and Zipp 303 tubulars and it handled pretty well. In fact it has a bit better damping than a few other frames in its weight class and that damping is going to aid control rather that make you quick to lose a line...
At days end, the review sounds like they handed a modern high end carbon bike with a reasonable 14-15pound ride ready weight to a guy not used to the class of bike...
I generally avoid poking at other reviews, but I think this one is off the mark.
I was right at home chasing down motorcycles coming off south mountain on the ULtralight... It's no place near quick to lose a line. I think the only folks that will mention the handling in the fashion the reviewer did are folks very simply not used to the direct handling and stiffness that several bikes in this class have...http://www.pezcyclingnews.com/?pg=fullstory&id=10575
