Full Speed Ahead SL-K Stem

The -20 degree angle is designed to lower your handlebar position significantly, which helps you achieve a more aggressive, aerodynamic riding posture. It is specifically built for time trial setups or road cyclists looking to optimize their front-end profile for speed.

This stem is compatible with handlebars that have a 31.8mm clamp diameter, which is the current industry standard for most modern road and gravel bikes. Always double-check your handlebar specifications before purchasing to ensure a proper fit.

While it is engineered for aggressive, race-oriented positioning, it can be used for gravel or endurance riding if you are specifically looking to lower your cockpit height. However, keep in mind that the extreme drop may be too aggressive for riders seeking a more upright or comfortable endurance geometry.

Yes, the 4-bolt faceplate provides a more secure and even clamping force across the handlebar compared to 2-bolt designs. This helps prevent handlebar slippage and ensures a more reliable connection, which is critical when you are putting extra power through the front end.

This stem has a stack height of 40mm. This measurement is important because it dictates how much space the stem takes up on your steerer tube; you need to ensure you have enough steerer tube length available to accommodate this height for a safe installation.
