CNC or Forging for Bike Parts: Where Cost Crosses
Forging is cheaper per part and stronger. Machining has no tooling bill and no lead time on revisions. Here is where the two cross for a bike component.

2014 and 2024 Aluminum for Bike Parts: When to Use
2014 and 2024 are strong, fatigue-resistant copper alloys that corrode and anodize poorly. When they make sense for a bike part and when 6061 or 7075 is better.

Titanium or Aluminum for Bike Parts: When Ti Pays Off
Titanium costs ten times more and cuts far slower. On bolts and axles it earns that back. On a stem body it does not. Here is where the line sits.

6061 vs 7075 Aluminum for Bike Parts: How to Choose
7075 is stronger, 6061 anodizes better and costs less. Here is how the two alloys behave in stems, cranks and mounts, and when the upgrade is worth paying for.
