There's a 110mm 7 degree stem on the bike now I have it angled up. It's a "62cm" endurance bike. I used Visio and did a to scale drawing, laying out a 110mm 7 degree line and putting a 17 and 20 degree line intersecting at the base of the original. You can measure the rise and change in reach this way. A 110 mm 17 degree goes up about .8" and gets about .2" closer to you in reach. 20 degrees is right at the 1" mark. If I use a 120mm angled stem it actually can be just a bit further away in reach and even higher than the 110.
