How do I find the right frame size using stack and reach?

Compare the stack and reach of the bike you want with a bike that already fits you, then choose the frame that gets you closest without forcing extreme stem or spacer changes.

Can a stem compensate for a frame that's the wrong size?

Only within limits. A stem can fine-tune reach, but it cannot fully fix a frame whose stack and reach are fundamentally off for your position.

Is standover height important for road bikes?

It matters for clearance and confidence, but it is secondary to stack, reach, and cockpit setup for actual riding fit.

How do I know if frame size is causing my foot or cleat issue?

If the discomfort stays in the same area and changes when you adjust one shoe or cleat variable, frame size is probably involved. If the problem moves around, check the next fit factor instead.

When should I replace shoes or get a professional fit?

Replace or get help when the shoe keeps causing hot spots, numbness, or heel lift even after careful adjustment, or when the problem is tied to asymmetry or persistent pain.
