Frameset Buyer's Guide — Semerubike

1. Start with your purpose

Decide whether you need an aero speed machine, a lightweight climber, an endurance platform, gravel explorer, or a mountain frameset. Your intended use should guide material and geometry choices.

2. Materials — Carbon, Aluminum, Steel, Titanium

Carbon offers the best stiffness-to-weight and can be tuned for compliance in specific zones — popular for road, tri and high-end MTB frames. Aluminum provides value and crisp handling. Steel and Titanium remain prized for comfort and longevity.

(Materials overview based on industry guides.)

3. Geometry & Fit

Stack & reach numbers tell you how a frame will fit. Endurance frames increase stack for a more upright position; race frames lower stack and increase reach. Always compare geometry tables and, if possible, book a professional fit before buying.

4. Compatibility & Standards

Check bottom bracket type, axle standards, brake mounts and tyre clearance. Ensure the frameset supports your preferred groupset and wheel size to avoid surprises during the build.

5. Road / MTB / Tri — differences to mind

Road frames prioritize lightweight and aerodynamics; MTB frames focus on strength, suspension integration, and wheel standards; tri/TT frames emphasize aerodynamics and integrated hydration/storage. Choose a frameset matched to the discipline you ride most.

6. Buying tips & upgrade path

  • Buy the best frameset & fit you can afford first.
  • Plan drivetrain and wheels in advance to ensure compatibility.
  • Consider last-season frames or demo units for value buys.

Bottom line: prioritize frame + fit, then wheels, then components.
