How do you determine the correct stem length?
One good rule of thumb for choosing the correct length stem (and it works for the road.cc team) is to sit on the bike with your hands on the top of the hoods and look down at the front hub. If the stem length is correct, the handlebars should completely hide the front hub.
What does a shorter stem do on a MTB?
Using a shorter stem gives the bike quicker handling characteristics and a more responsive feel. A longer stem shifts your body weight towards the front of the bike and puts you in a better pedaling position, especially on those steep climbs.
What should my stem length be?
As a rule of thumb, on a road bike you shouldn’t run a stem much shorter than 90mm or much longer than 130mm. If you need a stem length beyond those extremes, your bike frame is the wrong size.

To measure your bike’s stem length, measure between the two vertical points above. The stem rise refers to the stem’s angle in degrees, relative to the fork steerer tube, and affects bike positioning and reach.
How do I know if my stem is too short?
Look down at your bars and see where they line up in relation to your front hub. If the stem is too long the bars will be too far forward and the hub will be aligned behind the bars. If the stem is too short the hub will be aligned in front of the bars.
How much difference does stem length make?
‘A long stem length is effectively a longer steering lever arm, so will be less responsive but may feel more stable, particularly at high speed. ‘A short stem will be more responsive to steering inputs but potentially a little less stable.

How to Measure a Stem Extension (mm): The actual length of the stem from the center of the steering bore to the center of the handlebar clamp. We often refer to this as the stem length Reach (mm): The effective length of the stem measured from the centerpoint of the steering bore to the center of the handlebar clamp without accounting for rise.
What does mm mean on a bike stem?
Rise (mm): The effective height gained as a function of the stem’s angle and length. Measured vertically from the center of the handlebar clamp to an imaginary line that bisects the central meeting point of the extension and vertical portion of the stem.
What should I consider when buying a bike stem?
The first thing to consider when buying a new stem is the length. Not only does the stem length affect the fit of the bike, but it plays a big role in how the bike handles. Using a shorter stem gives the bike quicker handling characteristics and a more responsive feel.
