Ben, this is EXACTLY what happened to Sean at Track Day North a couple
weeks ago.  Strangely enough, this is also the second time that he's
sheared a hub!

I wonder if just preemptively replacing the ffront hubs once per
season would be the easier/cheaper solution (for track A1's) rather
than "upgrading" to A2 spec.  (I can get new hubs for $28 Cdn. jobber
price through a friend).  I've directly compared A2 to A1 hubs and
they're only a tiny bit bigger, so I'm not so sure you'd be gaining
much at all in strength/fatique resistance...

What about heat treating the hubs?  (or are they already treated?)

Later,

Mark.
