Default Re: Options to reinforce frame drop outs?

It has been proven that aluminum can be every bit as tough and strong as steel IF DESIGNED for the application.
Steel frames have a better safety margin when subjected to the extreme vibration a motor causes than aluminum frames.
The high frequency of two stroke vibes seems to affect aluminum more than four strokes, and can cause failures that pedal use would never cause.
Just my two cents, but I prefer steel for ht builds.
I would use aluminum for a four stroke with no worries aside from normal vigilance.
If more is better, then too much is just enough.
If you can't afford it, build it yourself.
