According to their website, "the Bar Mitts are specific for Shimano brake shifters. Campy and SRAM will be available soon."  I don't think that they will work for regular drops.You might want to contact them to ask.

For those of you with straight bars, here is a link to climitts that will work for you (http://www.sidetrak.com/Catalog/cooldays.html).  We sell them in our shop (they do have wholesale prices for your shops).  One of our volunteers has been using these for several years, and he says they work great, even during 5 degree days (with full gloves, of course!).  I just got a pair, and they seem to be good so far.  Time will tell...
