The tire clearance in the front and back is very much dependent on the fork and the chainstays. I have been lucky to run 700x38c on some of my setups, the front fork being the more limiting. Trial and error approach is best for most optimal results as you are building a sub optimal setup.
Very nice specimen. Have always liked Kastle Bikes. Still have a faithful Trekking Pro model from about that same year with the same paint and decal pattern.
Looking for help to ID this steel frame. It’s got ritchey dropouts and have taken pictures of the most prominent features of the frame. Seems to be TIG welded and decals on the top part of the Downtube that have been removed but still with some remnants that I still cannot make out.

I am glad I found this thread on Dan Falvey and Kastle. It was a unique bike brand, there was always something that set it apart from others.
