What it is
A stem connects your handlebars to the fork steerer tube, affecting your bike’s fit, handling, and aerodynamics.
Key features explained
-
1 1/8" steerer compatibility
This is the most common fork steerer size on modern bikes, so it should fit most road and MTB forks.
-
31.8 mm handlebar clamp
Standard size for most modern handlebars (both drop bars and flat bars).
-
Integrated aero design
The stem blends with the top cap and spacers to create a smoother airflow over the front of the bike—useful if you're chasing speed or a clean cockpit look.
-
Cable management system
Cables are routed under/through the stem instead of sticking out, improving both:
- Aerodynamics
- Aesthetics (clean, “pro” look)
-
Premium alloy construction
Lightweight but stiff, which helps with:
- Power transfer
- Precise steering
-
-10° angle
A slightly downward angle that puts you in a more aggressive (lower) riding position.
-
Multiple lengths (80–140 mm)
Lets you fine-tune your bike fit:
- Shorter = more upright, quicker handling
- Longer = more stretched out, stable at speed
Who this is for
This kind of stem is ideal if you:
- Ride road, gravel, or aero-focused bikes
- Want a clean cockpit with hidden cables
- Care about performance and fit optimization
