Mountain bikers and road cyclists, this RLECS disc brake adapter is exactly what you need when upgrading or replacing your brake rotors! The adapter converts IS (International Standard) mounts to PM (Post Mount) systems, which is super common when switching between different rotor sizes. This specific model works for front wheels converting 160mm to 180mm rotors, and for rear wheels converting 140mm to 160mm rotors. The aluminum alloy construction keeps things lightweight while providing plenty of strength for braking forces. The low-profile design works seamlessly with both hydraulic and mechanical disc brake systems. What's really convenient is the complete kit includes not just the adapter itself, but also 2 bolts and 2 washers - everything you need for installation in one package. Compatibility is excellent with popular brands like Avid, Shimano, Hayes, and most other MTB disc brake systems. The machining quality feels precise with clean threads and smooth surfaces that won't interfere with brake performance. Whether you're upgrading to larger rotors for better stopping power, replacing a damaged adapter, or just need the right mount for your specific frame and rotor combination, this adapter delivers reliable performance. Installation is straightforward if you're comfortable with basic bike maintenance - just make sure everything is torqued properly for safety. Definitely a must-have component for anyone working on their own disc brake systems or planning rotor upgrades!
