Ok, so, it's almost Xmas and we are FINALLY ABOUT TO GET SOME SNOW hopefully. My mountain/commuter/winter bike is this guy, a Surly Ogre with Maxxis Crossmark 29x2.1" tires:



It'll soon have a Nokian Gazza Extreme 294 and my dilemma is whether to try to fit it under some fenders or not. I have some 29'er fenders, but they barely clear the Crossmarks. I know the gospel is that full fenders are a must for winter riding, but I see many photos of people's bikes going without and I'm not sure if there are any fenders that could even clear a studded 29'er tire.

So what're people's thoughts: lose the fenders or the winter tires? Or is there some wondrously wide fender out there that'll let me run both?
