Try not running your tyres at max psi. Fine if you're riding on a perfectly flat surface but not on our roads.
Anyway, ^this. I opted to run 23s at 90psi front and rear this morning, because it was pissing down, and there was also the possibility I'd be in the saddle for 7 hours (*that *didn't happen, but the comfort would've been nice had it done). Absolutely no problem smashing into speedhumps repeatedly on a 10% descent at ~35mph. Very repeatedly. Then again, I'm like totally fucking awesome at riding a bike and shit, and float over road irregularities like the fucking Saviour walking on water.
