The length of the stem is a little like fork rake in that it can modify the steering response of the bike however it operates on a smaller scale.
Road bike stem length handling.
This is something that we have discussed in detail.
Once general compatibility is determined stem length is arguably the most important decision when choosing among various bicycle stems.
The best average stem length for modern mountain bikes falls between 50 mm and 80 mm.
Road riders like to choose stem length depends on overall bike fit and position for off road riders.
With the trend nowadays leaning towards longer and slacker bikes for a lot of people using a traditionally shorter stem makes sense.
Using a shorter stem gives the bike quicker handling characteristics and a more responsive feel.
For those aggressive trail bikes out there we recommend using a stem in the 50 60mm length range.
Stems also come in a wide variety of.
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.
Adjusting the stem length can be used to tailor the handling.
A shorter stem will result in snappier steering a longer stem will produce slower steering.
This in turn helps to stabilize the steering and give a slower response and better control while cornering.
It must also address the rider s comfort biomechanics performance needs and the steering and handling of the bike.
But that s only half the story.
I think it also depends on what type of bike geometry are we discussing.
Stem length will vary with the design of the bike.
The specific length of the stem is generally unimportant to overall bike handling.
Shorter stem lengths provide quicker and more responsive bike handling which is paramount for off road riding.
Stem length affects handling changing the stem length not only impacts your fit and comfort it affects the handling dynamics of a road bike.
Shorter stems are responsive and quicker handling which is a great advantage on gravity riding and single technical track.
Of course this may.
A longer stem tends to sift your body weight towards the front wheel thus shifting more weight to the front of the bike.
I like to keep the range of stems to between 80 and 120.
For road bikes this is primarily a question of dialing in fit as it has a significant impact on overall position on the bike with a shorter stem typically 100mm or less delivering a more upright position while a longer stem helps the rider achieve a lower and thus more aero position on the bike.
