can you ride in the drops at all? can you do it for 5 minutes straight? 10? an hour?

that's how you start. once you're flexible and strong enough in the right places do to that, you might start to feel cramped. that's when you look at lowering your bars, changing to bars with more drop, different stem, etc.

if you're not flexible enough to ride in the drops a lot right now, don't lower your bars yet. it won't help.

also, you could have saddle issues riding in lower. your hips will rotate and weight will be carried differently. it will hurt your junk if your saddle isn't right, or the angle isn't.
