Spank Spike, with or without Vibrocore, is the stiffest 31.8mm aluminum bar I’ve ridden. The 35mm Carbon Chromag BZA is still the only stiffer bar I can think of. Vibrocore definitely makes a comparative difference to vibration damping - of particular benefit to someone who wants the stiffest possible bar while paying less of a penalty through their hands - but it’s not a product on the same planet as the Fasst Flexx, which is actually forgiving.
Someone looking for the most “comfortable” solid bar is, in my opinion, best served by an aluminum Renthal bar, aluminum SQLab bar (if they want more sweep), or the OneUp (based on an aggregate of other folks experiences).
I actually did a [**back to back review**](https://nsmb.com/articles/save-your-hands-spank-vibrocore-bars/) of vibrocore a while back.
