shortening reach

Trying to shorten the reach on my recently acquired bike to match my main ride. Looks like I need a 90mm stem and a short reach 70mm handlebar.
Will these shorter components negatively effect the handling?

It'll feel twitchy. Less hand movement required to provoke the same reaction from the bike.

Another option could be to try a rear swept bar but I'm not sure if it would change that twitchiness much.

What size is the frame? A 90 mm on a smaller frame (say, 54 cm or smaller) wouldn't be out of the ordinary. And while it may not be optimal, the body adapts very quickly; you might notice it for a few rides but then you won't really think about it.

I doubt it will be noticeably or uncomfortably twitchy. Putting a shorter stem on is no different than riding the tops or last few inches of the drops. If anything, you'll have more control since you aren't reaching.

This is really one of those where you need to answer, it depends... crappy answer I know...

The geometry of the bike from the designers point of view will be perfectly balanced at a given weight distribution point. That is typically with the saddle set at center of the seatpost clamp and at a certain stem length. Colnago for example design their bikes with a longer stem (I believe their reference is a 120mm stem), Look design with a shorter stem (I believe they use 90mm as reference). Commonly that's a 100-110mm stem. The short you go from this point and the further you shift your weight distribution forward, the twitchier the bike will feel (which may or may not be an issue for you). The further you move weight distribution backwards and the the longer stem you have, the more sluggish the bike will feel, again, may or may not be an issue.

In general, staying in the range of 80-120mm is a non-issue.
