I'm new to bike touring and am planning some multi day test trips along the Katy trail (I'm at the trailhead in Saint Louis) as soon as the weather breaks. If all goes well, I want to do a long tour this summer.
The thing is that the Katy Trail is an old, converted railway line that's made mostly of fine gravel with some rough patches. I'm thinking it would be better to go with knobby tires but wonder what the forum thinks? I could also use some recommendations on general road touring tires in 27".
My bike is a mid 80's Schwinn Voyageur touring bike if that helps.
