What is the stem on a mountain bike?

Does a MTB stem make a difference?

What is the stem on a bike?

What stem length do I need MTB?

On most modern mountain bikes you should be aiming for a stem length somewhere between 50mm and 80mm. Long stems are more stable when climbing using narrow handlebars. That’s it.

How do I know if my stem is too short?

If the stem length is correct, the handlebars should completely hide the front hub. If you can see the hub in front of the handlebar, the stem is too short.

Does stem angle affect handling?

“A very long stem with a short top tube can slow the handling. If a rider’s hands are very far ahead of the steering axis it can be harder to steer at low speeds.” In contrast, a long stem may slow down the steering too much if the bike has a relaxed head angle.

How short should a MTB stem be?

Leisure riders – Don’t worry too much about weight and clamp design. Get a 80mm or shorter stem that fits your handlebar and that’s it. As usual, check the sale sections for bargains. Regular riders should try as short a stem as their bike frame’s top tube allows before it gets too cramped.
