New Gearing for the RB-1

An experiment: I swapped the 13-26 cassette for a 12-28. The short-cage Ultegra derailleur handed the oversize 28 cog w/o problems (26 teeth is max). The 12-tooth small cog is overkill, so I need a 13-28 cassette now. I do have one of those, but it's the ugly brown HG50 model...
