‘It’s a bit of a cliché that a too-short stem will over-quicken the handling. It’s only true to a point,’ says Phil Cavell, director of Cyclefit in London. ‘Needing a 70mm-80mm stem probably means bike sizing needs to be reviewed, but many riders are happy to ride a 70 or 80 or 90mm stem without difficulty.

Is a 80mm stem OK?

How do you calculate stem size?

Know the length by measuring from the middle bolt of the bike’s headset top to the center of the handlebar. Ensure that you measured the length in centimeters or millimeters. A bike stem length usually runs in 10 mm increments and starts from 70 mm to 140 mm.

Is 100mm stem long?

This size-specific approach goes a long way to getting you set up with the correct stem length, providing you’ve chosen the right size frame (another area where a bike fit comes in useful). Generally speaking, stem lengths on road bikes vary from 80 to 140mm, with 100mm and 110mm the most common sizes.

What is the standard stem size?

Stem Length Stem lengths span from 35mm to 130mm. Generally, if you feel too stretched you might need a shorter stem and if you feel to hunched you probably need a longer stem.

Is 90mm stem too short?

To put a (rough) number to it, a long stem is 100-120mm, very long stems are 130mm or more, and anything less than 90mm can be considered a short stem.

How is stem stack height measured?

If you are measuring stack height, assemble the lower part of the headset with bearings in place. Measure the from the fork crown race to where the lower pressed race would enter the head tube. Next, measure the upper stack from where the upper pressed race would enter the head tube to the top of the adjusting race.

Is a 90mm stem too short?

What is stem diameter?

Stem diameter is one of the most common measurements made to assess the growth of woody vegetation, and the commercial and environmental benefits that it provides (e.g. wood or biomass products, carbon sequestration, landscape remediation).

Is 110mm stem too long for 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.

Does a shorter stem affect handling?

The shorter stem definitely gives the bike a more responsive feel on the trail, and is well suited to aggressive riding. When jumping the bike or hitting drops, a shorter stem puts you in a better position to confidently hit these sort of features (that often have painful consequences if we don’t ride them well).
