Just found you a new one.
Opus Sentiero Cross bike
dropouts have Disc + Rack + Fender mounts
Tiagra drive train 9sp and road compact double 50/34 so one could easily swap the RD and cassette to use a MTB 11-34 cassette.
Not sure what is the fattest tyre it can accept. I found it at my LBS, so I'll go back with a caliper along with a test ride, see how it does
add: at least 700x45mm with some clearance left over. Probably up to 40mm with fenders will fit just fine. frame was too large for me, sigh.
