I'd be scared to ride in the snow with that saddle up so high myself though. I took the saddle/post out of the bike I was riding today in the snow, just so I could be that much closer to the ground when I fell (which I didn't, thankfully)
The bike looks cool with the snow on the tires. I have read about studded tires for motorbikes. A person could stick some roofing tacks through an old tire - if I lived there I might try it. The motor bike guys used to race on the ice.
Yeah, there is one on there. They do look cheesy. Ghost rings are way cooler IMO, or just proper tension if you can get it.
There is a cool topic somewhere on here regarding ice biking, with lots o links.
Now that you guys mention it I might take the chain tensioner off. The chain does slip over a little and rubs on the metal part of it slightly. I just put it on cuz it said to in the instructions. It does keep the chain nice and snug. I'm not sure if there will be too much slack if I take it off. I'll have to check it out sometime. Might be better off if the chains not rubbing.
