Effect Of Long Stem?

I am thinking of replacing a 100mm stem with a 120-130mm stem, to get more reach on a small frame.

What is the effect of a long stem on handling? Any deterimental effect I should think about?

This is on a 52 cm 1992 Cannondale R1000 road bike. I would also eventually switch from downtube shifters to brifters, which would extend the hood position another 1-2 cm further forward.

Is it a 1" quill stem with zero or negative rise, by any chance?

At anything much above walking speed, leaning is by far the largest component of steering, so stem length is a negligible contributor to handling. If you end up with a better-fitting bike with a longer stem, that's an unadulterated win.

That does it. I'll look for a loooong quill stem. I like everything about this bike except the too-short cockpit.

Does one lean when on rollers?
