Tube Failure Caused Crash?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

"In this scenario I assume the rider usually operates the brake levers with palms. A situation that calls for even just moderate application of the brakes (and/or grabby brakes) could cause the rider's weight to fall still harder onto the brake levers and result in a positive feedback loop that eliminates all possibility of any brake modulation. Worst-case scenario would be an endo. For the performance-minded there are many reasons not to turn up drop bars like this--not the least of which is the risk of un-weighting the front tire, but I think if levers can be installed in front of the handlebars to prevent the aforementioned feedback loop then for utility riding you might as well give this a shot."


So the cause is explained by physics. I will need to reposition my brakes keeping a handlebar height comfortable for my neck. May require new handlebars or a riser of some sort.
The ergonomic reasoning behind drop bars is that you can put a lot of weight on the “hooks” without issues. On really hard descents (8-10%) with lots of braking, I’ve noticed that my arms and shoulders will start fatiguing quite quickly. I think many people underestimate how much force goes into your hands when you brake hard. Pretty much your entire body weight is slowed down through your hands, with a minor amount from the pedals and saddles.

I agree that you should look into a riser of some sort. Something like this: https://www.performancebike.com/delt...d3318b/p335420

Flat riser bars that are cut down to road bike widths may also be appropriate, but you’d need a different brake/gear setup.
