The Elite X4 Mountain Stem is instantly recognizable because of Thomson's legendary style, and with strength to spare, this stem is more than just a pretty face. Made from a solid, one-piece block of 7000-series aluminum, the X4 combines exceptional strength with light weight for durable, solid steering control to tame the toughest trails. It has a four-bolt clamp design and reversible graphics, so your X4 looks great whichever way you run it.
Stem length is measured along the top from the center of the steerer to the center of the handlebars (diagram).
Tip: Keep in mind that as stems provide more rise, their effective length decreases. In the example above, if the +17 Degree stem measures 135mm, it actually extends only 108mm when length is measured on a line parallel with the ground.
