I've snapped several.

Me too, I don't have positive memories of square taper bb's on mountain bikes, more than once I got hurt from broken bb spindles.

I didn't break one myself. But I've seen it happen to others. Luckily the poor guy wasn't clipped in.

Mine were all from my courier day.

How many spindles breaking in one day as a courier does it take to get the hint?
This job is not for you.

I still remember the big stiffness increase going to ISIS. Then again from ISIS to GXP/HT2. No more chain rubbing the front derailleur under hard pedalling.

But I'm pretty sure we're past limits of detection going from GXP/HT2 to BB30.

Yup, both of those.
May as well go back, no more front derailleur to rub against anyway.

Now I'm all paranoid
I like the FSA tempo cranks I got and I like the shimano square taper unit - it screws in using metal on metal which I like, it's very solid feeling, it's very metal all over. It has no play... There's a lot to like but now you all made me sad

Ignore the BB shamers, your square gaper is beautiful

It'll be fine blaboon, all these broken bb's were done playing silly buggers I bet. When I was a courier I was 100kg, fit and strong, running 48:16 gears... Something had to give.
