The RHM 02 has flattened tops, which were actually very comfortable (I put them on a bike I built for my brother, and now I want a set for me). The RHM 01 did not. If you are really on a tight budget, Ribble seems to have some of the best prices on Deda stuff. I didn't look at the numbers, but my recollection is that they are a very short and shallow bar.
