Length (e.g. 80mm, 100mm)

Like

The length of a bike stem refers to the distance (in millimeters) between the center of the handlebar clamp and the center of the steerer tube clamp. The length of the stem can greatly affect the handling and comfort of your bike. For riders looking for a more responsive and aggressive ride, a shorter stem length, such as 80mm, is recommended. Shorter stems provide quicker steering response, making it easier to maneuver through tight corners and technical trails. On the other hand, for riders seeking stability and a more relaxed riding position, a longer stem like 100mm can be a better choice. Long stems provide better stability at high speeds and make it easier to maintain a more upright posture.

One example of a shorter stem is the RaceFace Turbine R Stem. It comes in various lengths, including the 80mm option, and is made from 7075 aluminum alloy for lightweight and durability. Another option for those looking for a longer stem is the Thomson Elite X4 MTB Stem, available in lengths up to 100mm. This stem is constructed from high-quality 7000 series aluminum and features a four-bolt steerer tube clamp for added strength. With these options, riders can choose the stem length that best suits their riding style and preferences.

Rise (e.g. 6 degrees, 10 degrees)

Like

The rise directly affects the overall height and reach of the bike's cockpit. Stems with a higher rise angle, such as 6 degrees or 10 degrees, will raise the handlebars, resulting in a more upright riding position. On the other hand, stems with a lower rise angle, such as 0 degrees, will lower the handlebar position and promote a more aggressive and aerodynamic riding posture.

For those looking for a higher-rise stem, the Ritchey WCS C220 6 Degree Stem is a great option. It features a rise of 6 degrees and is constructed using forged 2014 alloy for increased strength and durability. Another option is the Race Face Atlas 10 Degree Stem, which offers a higher rise of 10 degrees and is machined from 6061 aluminum for a lightweight and performance-oriented design.
