Tom, I didn't fracture one of these but I did bend the rails - and I weigh 60 pounds less than you do! In my case, the rails bent when I "landed" after hitting a bump at speed and going out of the saddle. I think these saddles are nice for display purposes and perhaps limited time trial use, but I wouldn't use one for regular riding. Best regards, Fred Rednor - Arlington, Virginia
