How do you measure a road bike stem?

To measure your stem, you first need to mark the center point where the stem attaches to the bike frame and the center point where it attaches to your handlebars. The length between the two parts is always shorter than your true stem length.

Is 80mm stem too short?

For someone your size, 80mm is too short. The fact that you can see the hub means the weight balance is shiftied backwards.

How long should my handlebar stem be?

Ideally, the stem should be long enough to place some of the rider’s weight over the front wheel to stabilise the steering and improve grip on the road. At the same time, the stem should provide a steering arc that complements the head angle and trail of the bike.

What difference does a shorter stem make?

A shorter stem will result in snappier steering, a longer stem will produce slower steering. Adjusting the stem length can be used to tailor the handling. That’s generally why cyclocross races use a shorter stem, and long distance road cyclists opt for a longer stem.

What is the shortest bike stem?

30.2mm is the minimum you can get but for safety measures the shortest you will get is either 30.5mm or 31mm, my money is in the 31mm. But you can try more unconventional options, like one of the OnOff Stoic stems, either 10mm or 20mm.

What is the best stem length?

How do you find the angle of a stem?

To measure the angle of a stem, we place the stem on a horizontal surface and measure the angle that the stem rises above the horizontal. Because most treadless stems are reversible, a stem with a 10° rise could be flipped around to serve as a stem with a 10° drop.

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.

How does stem length affect handling?

‘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.

Can I use a MTB stem on a road bike?

2 Answers. For XC and trail use it’ll be fine. It’s really only downhill bikes that require especially strong stems, I think (and in that case you’d likely be using a shorter stem anyway for handling reasons). … Oversize bar is 31.8mm for both road and mountain bars, so the stems are interchangeable.
