4mm = 1/8" A
very small difference. The Cannondales have very long stays and shouldn't have any problem with the flex. My 2003 T800 comes with a 132.5 OLD so that you can use either a 130mm or 135mm hub. Yes, it's only 2.5mm difference but that's only 1.5 mm narrower than 4 mm. That's practically a hair's width
It's not an issue. I've even retrofitted a 130mm road hub into a 2.8 Cannondale frame. That's the really, really short Cannondale frame. No issues.
