Decision guide / For riders choosing a chinese frame or wheelset
Check the interfaces before choosing a carbon frame or wheelset.
An unresolved bottom bracket, axle, freehub or tyre interface can stop an otherwise plausible build.
Work through the question.
- Select exact models and compare the documented interface specifications.
- List every missing or conflicting field and request written confirmation for the exact year and variant.
- Keep structural condition, fit and independent safety checks separate from catalogue compatibility claims.
Start with checked examples.
