I was looking at Stems and noticed that they have verying lengths. How do you know what the right length Stem is you need. I have a SL and on the site it suggest a 110mm for my height. I was just curious to know how you guys/gals find the right lenght.

And what is the ride difference between a 5 deg. and 15 deg. other then 10 deg and a more upright riding position.

Thanks

It's personal preference. The best thing to do is to go to a good LBS and have them fit you. They should choose the stem length and angle that will allow you to assume a "correct" riding position. Riding positions vary from rider to rider, based on riding style, age, medical conditions, etc.

Your goal is

Basically your goal is to create a proper "cockpit" on your bike which includes seat height/position and bar reach/height. Given that you will need a certain frame size depending on your standover height, reach is adjusted by choosing the correct stem length after you've dialed in your position over the pedals.

There are a lot of variable to play with up front incld.... riser bar or flat, stem spacers, & stem angle/length. When I got my bike, I had them change the length of the stem because I felt like I needed to stretch out more, but some people like to be more upright. Depends on what you're used to and the type of riding you do.

Stem length effects steering, and by extension how you bike handles, in a big way. Personally I like a quick steering bike so a 90mm stem is good, it also helps you get over the back. If you want a more aero position, you can always lower the stem rather than go for a longer one.

here's some help...

As the others have said, its trial and error. To help make it easier try looking at the chart on this web site: www.habcycles.com/fitting.html. Otherewise, the best way is to borrow stems from your friends who have already gone thru the same process. Also, the older you get (ugh), the more upright a riding position you usually prefer. When I started mtbing about 15 years ago, my bike had flat bars with a 130mmX0 stem. Now, several bikes and stems and years later, I am using 1-1/2" risers on a 75mmX10 degree stem on an original Heckler, and it never felt better.

150mm long, Zero deg rise, with 21" flat bar.

the only proper stem, especially for DH racers, is this:

150mm long, zero deg rise, with 21" flat handlebar.

disc brakes are for wimps.

suspension is for geeks.
