I've been kicking around taking the fenders off my Norther for a few weeks now so I could slap my 47mm tires on. Really glad I finally did as my local shop did a ride yesterday. The plan was 10ish miles on mostly pavement but after the only folks who showed up with very much bicycle people we opted for something more like 25 miles with about 20 of it gravel and dirt and the woods. I'm the bike in the lower left, but we did cross this excellent old railroad bridge.
