WTB: Beater Cross Bike (lend/lease/buy/trade)

Just catching the bug to enter some cyclocross events. My road bike is 61cm, and the rim brakes won't let me put anything larger than a 28 cm tire on. My MTB is a 27.5+, so it doesn't make sense to ride with that either, if avoidable.

Looking for a heavily used 58 or 61 cross or gravel bike. (I'm 6"2") As long as I can get clearance for a 32~34 tire on it, I should be fine.

Something in the basement collecting dust while you ride your new all-carbon, rocket powered, handbuilt cross machine? Project gone awry? Send a PM!
