Aluminium Alloy Disc Brake Adapter Post Mount to Flat Mount Disc Brake Adapter Bike Upgrade Kit

Label:Yes Easy Installation: The adapter installs with simple steps and fits many mountain frames that need a road-caliper conversion setup. It serves as a useful replacement or upgrade part for riders who want flexible brake compatibility across different cycling environments. Main Function: This adapter allows a road-style caliper to be installed on a mountain bike frame or fork. It supports mounting a brake with a 34 mm(1.34 in) hole spacing onto a base with a 74 mm(2.91 in) hole spacing, offering a practical setup for riders who want to use different brake styles on one bike. Size Compatibility: The adapter works with specific rotor sizes depending on setup. One version fits 160 mm(6.30 in) rotors and requires at least 25 mm(0.98 in) from the top of the screw hole to the frame. Another setup fits 180 mm(7.09 in) rotors for both front and rear use. Riders should check rotor size and frame spacing before purchase. Aluminum Alloy Build: Made with CNC-machined aluminum alloy and finished with an anodized surface, the adapter offers steady structure for long-term cycling use. The package includes the adapter and four screws, two for the caliper connection and two for securing the adapter to the frame or fork. Lightweight Structure: The design balances strength and reduced weight through a hollow construction approach. This helps decrease overall bike load while maintaining steady performance during daily rides, training, or longer trips.
