- Replacement parts and warranty: Consider brands that offer replacement extenders or bolts and provide reliable customer support.
- Budget considerations: Prices vary; balance cost with material quality, ease of use, and compatibility with multiple bikes.
- Safety certifications and reviews: Read user feedback focusing on stability, fit, and long-term performance to gauge real-world effectiveness.
