Hey guys, I have been interested in CX for a while, but only went to my first race a week ago. It was enough to set the hook. There's one more race this season, and I'm thinking about jumping in. I don't have money for a second bike, and I don't know anyone with a spare cross bike anywhere near my size (I'm a big dude), so I'm gonna jump in on my FG rig. I'm gonna grab some tires from a friend, and throw a freewheel and rear brake back on.
Now to the advice: I'm currently running 46/16 gearing, which is beautiful for my daily urban riding, but I'm hearing that it'll be way too steep for SSCX. What size freewheel should I grab?
The tires I'm borrowing are 700x35 Bontrager Aramid HD. They gonna work?
Also, I've never tried CX at all. Anything I need to know that friends may not have told me?
