Just out of interest , I was curious as to where and why peoples frames have been breaking . If you have the time ... please describe your frame brake here . It may turn out to be usefull info for us all . 1: Be exact as to the location of the break ( don.t just say ... the down tube ) . Did it break an inch away from the neck ? an inch above or bellow the front mount ? on a weld where the ... and the ... join ? the exact location . 2: And then your thoughts as to why it broke . engine vibration fatigue ? sudden shock ( like going over a big jump ) ? constant riding down rough roads ? loose wheel , part fell off ? crash ? Poor engine mounts or mounting ? I drilled a hole neer there ? 3: What kind of frame , and the type of material its made of . Steel , Aluminum , Chromolly ? Brand ? The store i got it from ? Old ... New ? Rusted out fixer-upper ?
