[MENTION=124730]SJX426[/MENTION] - You know your commute better than anyone else, if rolling up those fatties wasn't quite enough adding the suspension fork is a logical choice although it does change the geometry of the bike as it was not designed for a suspension.

I ride a Diamondback rigid mtb that was designed for a suspension fork and uses a suspension corrected rigid fork and just changed the 2.3 tyres to some slightly faster rolling 2.2's and these feel great at 45 - 50 psi... they are Bontrager Jones ACX folding tyres and these tend to be lighter, more supple, and deliver a much better ride than most wire bead tyres.
