Same bike, I just throw the studded tires on. Depending where you are, you may or may not need them. See how much clearance you have at the chainstays near the bottom bracket and at the fork to see how much of a wider tire you can fit. If you area uses lots of salt on the roads, you might not want to use your nice bike during slushy, snowy or snow melt commutes. Salt will cover your bike, fenders help a lot, but the salt can really damage the finish on polished aluminum and help to seize components - pedals to cranks, cogs to hubs, and bottom brackets to bottom bracket shells.
