There is the Cycle Depot in Jefferson City, which is really not that far off the Katy and they do repairs. I had them true a wheel and replace some broken spokes one time while biking the Katy. They did this while I ate lunch at the café next door. This site list other bike repair shops in Boonville and Sedalia so there are other options also.
