Pre-bled hydraulic rear brake kit built around the Ultra Bee caliper, with a CNC-machined bracket and 220mm rotor sized for Super73 and Ridstar Q20 frames.

• Compatibility - fits Super73 and Ridstar Q20 rear brake mounts; bracket is machined specifically for the Ultra Bee caliper, not a universal fit
• Pre-bled caliper - arrives ready to install; no bleeding required before first use
• 220mm rotor - oversized versus stock for improved heat dissipation and stopping consistency on heavier builds
• CNC bracket - machined for alignment and clearance with this specific caliper; not compatible with other brake brands without modification

• pre-bled ultra bee rear hydraulic brake assembly
• cnc-machined mounting bracket
• 220mm rotor
• installation hardware
