Length again?

By Gideon

30 Mar 2020

Hi, sorry, still unclear. I'd like to know if the 90mm is measured along the length of the stem (at its 40 degree angle), or if it is the distance forward (flat to the ground, in what might be called the x axis). As the stem is very angled, if 90mm long, it will only reach forward about 70mm. If it reaches 90mm forward, at 40 degrees, it needs to be about 125 long. Does that make sense?

SJS Customer Service:

The measurement follows the line of the stem, all stems are measured this way.

What is the definition of length?

By Roger

Please can you tell me how length is defined for all these stems? I can think of at least 4 possibilities.

SJS Customer Service:

The length is measured from the centre of the steerer tube to the centre of the handlebar.
