PS-B05 Post Mount Brake Boss
PS-B05 Post Mount Brake Boss for fork and frame post-mount disc brake interfaces. Includes mapped product render, dimension drawing, asset status, engineering notes, and CAD request support.
Engineering Role
This disc-brake interface component supports drawing-controlled post mount, brake boss, and caliper stack applications where thread engagement, shoulder height, and brake alignment must remain consistent across production batches.
PS-B05 Post Mount Brake Boss is mapped from the PremFixer technical asset library with source reference 650-490-317Y. The page keeps the render, drawing, and CAD status together so engineering and sourcing teams can review the item before sending a formal RFQ.

Dimensions & Interface Control
Use the mapped dimension drawing to confirm post mount brake interface, boss height, caliper stack, and thread axis. Final production dimensions should follow the customer drawing, mating component, assembly stack, and bicycle brand service requirement.
- Main image and dimension drawing are linked in the media panel for quick visual review.
- Confirm mating parts, frame material, coating stack, torque path, and service access before sampling.
- Custom length, profile, thread, hole position, finish, and packaging can be reviewed during RFQ.
Material, Process & Finish
| Material direction | Heat-treated alloy steel or drawing-specified material |
|---|---|
| Process direction | CNC machined and heat treated |
| Finish options | Black oxide, e-coating, zinc nickel, or drawing-specified finish |
Material and finish are selected against the drawing, corrosion target, weight requirement, and mating assembly. Alternative grades or coatings can be reviewed when the application needs higher strength, lower weight, better wear resistance, or a specific cosmetic target.
Quality & Traceability
PremFixer can support drawing-based inspection for thread gauges, shoulder height, coaxiality, surface finish, hardness, and corrosion protection. Batch traceability, incoming material checks, coating reports, hardness checks, salt-spray validation, and dimensional reports can be prepared according to project requirements.

Start RFQFrequently Asked Questions
Confirm fit, drawing control, finish options, and documentation before RFQ.
Q1 What applications is this brake mount suitable for?
This disc brake mount is designed for bicycle fork and frame brake interfaces. Final compatibility must be confirmed by frame drawing and brake mount specification.
Q2 Can I order custom dimensions or materials?
Yes. Submit a 2D drawing or STEP file with material grade, finish, quantity, and inspection requirements. Alternative materials (6061-T6 aluminum, 316 stainless) available for review.
Q3 What surface finishes are available?
Standard finishes include black ED coating (240h NSS), zinc-nickel plating, and anodizing for aluminum variants. Salt spray requirement available by project specification.
Q4 Do you provide material certificates?
Material certificates and inspection reports are available on request. Batch traceability, coating reports, and dimensional reports can be prepared per project requirements.
