quinton Posted August 5, 2007 Share Can anyone tell me who you calculate the length of a stem?? Is it from the center of the stem to where the "front" plate screws on or end to end? Thanks Link to comment Share on other sites More sharing options...
Dicky DQ Posted August 5, 2007 Share Why do you want yo know?? Get your bike setup properly, who cares about the actual lenght of the stem. The old rules of thumb. as I recall them are: MTB - see the front hub in the middle of the stem........Road - not able to see the frontr hub as it is hidden by the bars on you are on the hoods...... Things may have changed, but this is what I recall. Link to comment Share on other sites More sharing options...
quinton Posted August 5, 2007 Share I recently changed over to another bike and did a long ride with ittoday and got lower back pains. From searching around on the web, thefirst point raised is an incorrect stem length and saddle position. SoI am trying to figure out what the exact length of the stem that is onmy new wheels. If I can picture it correctly I can actually see the hubs without having to lean over the bars.... The options to replace it if needed: 70mm, 75mm, 80mm, 90mm, 100mm, 105mm, 110mm, 120mm, 130mm, 140mm. Picture below. Link to comment Share on other sites More sharing options...
Dicky DQ Posted August 6, 2007 Share My recomendation os to measure it any way you want to then go to your LBS and tell them what method you used and they can then measure another one in the same way. From this you will have a reference for all other types. Link to comment Share on other sites More sharing options...
SwissVan Posted August 6, 2007 Share Can anyone tell me who you calculate the length of a stem??Is it from the center of the stem to where the "front" plate screws on or end to end?Thanks To measure the length: "from the center of the stem to where the "front" plate screws on" would be the correct measurement, usually in mm. http://www.lhthomson.com/docs/006_X4_Stem.pdf No real way to calculate the correct length, this depends on your your age, degree of flexability, frame size, type of riding ect.. starting point would be as per Dick's method, generaly go longer if you want and can comfortably maintain a low upper body position, and shorter if you cannot comfortably maintain a low upper body position.
