Ride with Precision: CNC Machined Bike Stems by RALLY
At RALLY, we offer premium CNC machined bike stems, meticulously designed to amplify your cycling experience. Crafted with precision, our stems ensure unmatched control, durability, and optimal weight balance, delivering an extraordinary ride every time.
Materials for CNC machined bicycle stem:
Aluminum 6061:
- 6061 Aluminum is a medium to high-strength alloy, making it apt for structural bicycle components like stems. Its tensile strength and fatigue resistance ensure the stem can withstand the varied stresses of cycling.
Aluminum 7075:
- 6061 Aluminum is a medium to high-strength alloy, making it apt for structural bicycle components like stems. Its tensile strength and fatigue resistance ensure the stem can withstand the varied stresses of cycling.

Our CNC Machining Capabilities

CNC Milling
This process uses rotating tools to remove material from the HDPE block in a controlled manner, creating a variety of parts with complex geometries.

CNC Turning
Ideal for producing cylindrical or round parts, a CNC lathe spins the HDPE material while a cutting tool shapes it.

CNC Drilling
CNC machines can accurately drill holes of various sizes and depths into HDPE, important for parts that require precise holes.

CNC Grinding
For high-precision finishes and tight dimensional tolerances, our CNC grinding service is your ideal choice.
