I do long, spirited group rides in the flat plain around here, and would like closer ratios at the high end. A 12t would be nice for tailwindy days as well. If someone made a 13-19 7sp freewheel I'd be all over it, but my only option there is ludicrously expensive non-Hyperglide Regina or Sachs from eBay.
