Personally I'm not big on the "fit". I do have some idea of what is close, and do tinker a bit. But, have now gone from a one-bike person to a two (or multiple) bike person, each with a bit different fit.

At most, if you think of 3 attachment points to the bike. Cranks, seat, and handlebars, then you can set those 3 points with a variety of bikes by changing your stem and seat positioning.

What kind of bike are you riding? I've seen a few other threads about a Giant Roam Hybrid??? One of the things that comes up is the ability to change hand positions. With the hybrid you're pretty much locked with a single hand position.

With drops, one often naturally moves from one hand position to another, from the drops to the hoods to the tops and etc. Sometimes I'll find new and unique hand positions. For example, sometimes simply holding on to the knobs on top of the brake levers, of just hanging on with a few fingers.

Bar ends, and perhaps Ergon grips may help a bit with your hybrid. Also consider touring butterfly bars.

Not the vegan guy He is, however, a strong cyclist. So much is in the rider. And, yes, there is quite a bit of trickle down technology.
