I have a 2013 Trek 7.2FX (25" frame) with a 90mm long stem and a 10 degree rise.

The handlebars feel like they're too close to me, and I'm kicking around the idea of getting 110mm long stem with a 20 degree rise.

With a 72.5 degree headtube angle, the steering is very "twitchy" (sensitive) in stock trim.

My question is: will moving to a longer stem and a higher rise perceptibly effect the handling/feel of the bike? If so, what could I expect?

Thanks for your input!
