Unless you need to have a bike to fit some kind of class regulations, forget what other people might call it and have fun playing around with parts to see if they work for you. In the late 1970s my Carlton Continental ended up being what people today might call a gravel bike but to me was just an experiment in available parts to get the best out of riding on and off road. Today I buy very cheap old bikes to raid for parts and will put up with inconveniently placed levers and gearchangers just to try out some different bars.
