I find reviews mostly meaningless. Handling is primarily determined by geometry, wheels, tires and air pressure. I would love to read reviews that have been done blindfolded, without the reviewer knowing what he or she is riding. But it's not happening for obvious reasons. Also, everyone seems to be able to give reviews about wheels and frames and whatnot, no matter how technically proficient he or she is. Today's disc bikes are so balanced and differences in handling are so small. I had a look at the geometry chart of the SC-R48D and I was already pretty sure I knew what I could expect in terms of handling. Of course, I may be wrong but then I'm the first to acknowledge that. To be perfectly honest, the main driver why I ordered it is because of its simple look, round seatpost, external cables (I have plenty integrated bikes), light weight and EPS molding technology.
BTW, the frame head tube is tapered 1 1/8” - 1 1/2”. I thought I read here that the upper section is 1 1/2” which it isn't.
