figuring out rise on stem(7 posts)

I forgot what the degree of the rise mean. If I want the handlebar to be level(i think that is the word to use) what degree do I need for a road bike. Also, do i need to buy the same make for stem and handlebar? Does the size of the headset determine the stem size?

thanks

No need to match manufacturers, though you do want to check diameters. Your LBS should be able to tell you. On most road bikes (with approximately a 73-ish head tube angle) a -17 stem will give you the appearance of perfectly flat bars. I've got a -7, and it gives the bars the appearance of rise, though not so dramatic as a 0 or plus stem.

Your final question confuses me: Does the size of the headset determine the stem size. You mean 1" or 1 1/8"?

Yes, I mean one inch threadless headset. Also, what is an 80 degree or 90 degree rise mean?

Thanks
Usually a stem with a '90' degree rise.....gogene

....will be perpendicular (90 degrees) to the steer tube. An 80 degree stem, also called a -10 degree stem, will have a "rise" that is more horizontal than the 90 degree stem. A stem that is horizontal, as Jtolleson pointed out, is a 73 degree stem, also called a -17 degree stem. There, isn't that clear?

You don't need the same brand.

You do need the same clamp diameter, where the stem holds the bar. Standard sizes are 25.8 or 26 mm. Oversize is 31.8mm, stem and bar must match.

This chart shows you how to pick a stem with the appropriate rise and reach you are seeking.
