you know last summer I was riding the drops a lot more, over the winter I've been riding a MTB with flat bars, and getting back on the fixie with track drops I'm finding it a little bit difficult to get used to. I think it's partly about flexibility. After a winter of short rides in an upright position, I'm just not as limber as I was.
Raise the bars a little bit, and give it a little time. When I first started riding road bikes again after years on the flat bar I was surprised how often I found myself dropping into the drops. I especially like them for climbing, and for descents although I haven't tried bullhorns which are supposed to be great for climbing. ANother reason I haven't been using the drops as much yet this spring is I'm a bit out fo shape. When I'm feeling good I like to grab a fistfull of drop and sprint around, but right now I'm happy to just spin it out.
