MTB Pivot Bolt Kits & Matched Hardware

A pivot kit can include bolts, axles, sleeves, spacers, nuts and retaining parts. We manufacture the agreed components and organise them by suspension location, drawing revision and quantity per bike.

Define each main pivot, linkage joint or shock mounting stack separately. Shoulder length, bearing and spacer contact, mating threads, installation side and tool clearance belong to the assembly definition. These photographs show representative groups; the complete kit contents follow your BOM.

03 / Hanger fixing

Derailleur Hanger Fixing Bolt & Nut Sets

We manufacture hanger fixing bolts and mating threaded nuts or sleeves for the specified retention arrangement. These parts secure the hanger to the frame; they are distinct from the derailleur’s own mounting bolt.

Head seats, clamped thickness and usable thread engagement must work together. Specify countersunk or flange contact, thread direction, anti-rotation features and tool access using the actual hanger and frame-interface drawings.

Chainring Bolt & Nut Sets for MTB OEM Projects

Chainring sets combine the specified bolt and mating nut or threaded barrel. We manufacture these parts to the mounting arrangement, seating geometry and required engagement in the approved assembly.

Send the chainring and spider or crank interface, including any guard or spacer in the clamped stack. Hole form, head seat, bolt length, barrel length and two-sided tool access define the combination. Quantities follow the actual model configuration.

Crank fixing bolts and direct-mount chainring interfaces are separate requirements. Direct mount does not necessarily use this bolt-and-nut arrangement. Direct-mount example ↗

Beyond the three core kits

Other Frame & Assembly Hardware in Your MTB BOM

For each group, identify the mating interface, drawing, quantity and purchasing owner. Component-maker-specified fasteners require the appropriate design approval before substitution.

Shock mounting

Mounting axles, bolts, bushes and washers for the defined shock-to-frame connection; shock internals remain separate.

Axle & retaining parts

Drawing-controlled shafts, sleeves and retaining pieces. Confirm the wheel and dropout interface.

Shafts, axles & pins →

Seat clamp hardware

Clamping bolts and threaded parts for the seat assembly. Supply the mating clamp and contact geometry.

Frame inserts & bottle mounts

Threaded inserts, weld nuts and accessory fixings, separated by frame-stage or final-assembly supply.

Original shaft and spacer drawings illustrate individual component documentation, not a verified pairing or a model-specific kit.

Match the frame architecture

Different Models. A Defined Scope for Each.

Full-suspension MTB

Pivots, linkage and shock mounting join the other hardware systems. Joint count and dimensions follow the frame design.

Hardtail MTB

Hanger fixing, drivetrain mounting, inserts and other assembly items; no rear-suspension pivot kit.

Hardtail programs →

e-MTB

Start with the actual hardtail or full-suspension architecture, then add agreed external motor, cover and housing fixings.

Motor mounting scope →

XC, Trail, Enduro and DH describe use conditions, not dimensions or material grades. An e-MTB label alone does not define tightening torque.

One project / itemised supply

One MTB Model, One Defined Hardware Schedule

Each component keeps its part number, revision, material and quantity. The quotation brings multiple systems together and identifies what PremFixer manufactures, what requires sourcing confirmation and what another supplier provides.

Count and quote consistently

Define piece, pair, set and kit units. Keep build quantities, prototypes and extra spares separate. Do not quote the same bolt and nut both as individual lines and again as a pair.

Add material condition, finish, acceptance records, packaging group and total quantity. Consolidate shared parts across configurations only when the approved part and revision match.

Which items are already supplied?

Mark frame-stage parts, frame subassemblies, final-assembly purchases, component-supplier items, customer-supplied items and mating references. Hanger bodies, chainrings, bearings and seals are included only where the order says so.

Separate tooling, finishing, inspection documents, packing and delivery groups in the quotation. Name the design approver, buyer, assembly site and receiving site.

Choose the route for each part

CNC turning produces shafts, sleeves, shoulders, end faces, bores and suitable threaded features. Turn-mill machining adds cross-holes, flats and slots to rotational components. Cold heading and tooling suit appropriate materials, shapes and production quantities; thread rolling applies to suitable external threads.

Our core manufacturing is coordinated with project-specific finishing, heat treatment or specialist testing where partners are required. The quotation and control plan identify responsibilities and acceptance evidence.

Specify materials by line item

Options include 304/316 stainless steel, 6061/7075 aluminium, titanium such as Ti-6Al-4V/TC4, and project-specified steels. Record grade, condition, finish and finished requirements for each part. These are material choices, not universal upgrades for every mounting location.

Check the finished interfaces

Inspection follows the released drawings: threads, shoulder or barrel lengths, contact faces, fit after finishing and edge condition. Agree sample checks and records before production. Similar appearance does not establish interchangeability, and a dimensional check does not replace assembly or vehicle validation.

Identify who approves design changes, who accepts samples and who validates the assembly. Revised mating parts must be considered together.

MTB Hardware Supply Questions

What can be included in a model-specific MTB hardware supply program?

A project can include pivot hardware, hanger fixing components, chainring bolts and nuts, and other agreed frame or assembly fasteners. The approved BOM defines the actual items, materials, quantities and revisions. Parts already supplied with a frame, crankset or other component should be identified so the quotation covers the hardware you need rather than duplicating another supplier’s scope.

Is a pivot bolt kit the same as a complete MTB fastener kit?

No. A pivot kit covers the specified suspension joints and their agreed bolts, axles, sleeves, spacers or locking components. A broader MTB hardware program may also cover hanger fixing, chainring mounting and other assembly areas. The description of a kit should always resolve to an itemised part list, not just a product photograph or a generic kit name.

Can you manufacture matching derailleur hanger bolts and nuts?

Yes. We manufacture drawing-defined hanger fixing bolts and mating threaded components. Send the hanger and frame-interface information together with the fastener drawings where available. Seating geometry, clamped thickness, thread specification and access determine the intended pair. Existing catalogue examples provide manufacturing references; they are not evidence that any two similarly named components are interchangeable.

Are these hanger fixing sets universal or automatically UDH compatible?

No. Hanger retention arrangements differ, and a UDH-compatible frame interface does not make every fixing component interchangeable. Full Mount is a separate mounting arrangement that replaces the hanger. Identify the actual design and applicable component requirements before defining the supply scope. Compatibility is established through the approved project information, not a general MTB or UDH label.

Can you supply chainring bolt-and-nut sets for an OEM project?

Yes. We manufacture the specified chainring fasteners and mating nuts to the agreed drawings. Include the mounting interface, clamped stack and any guard or spacer that affects the required combination. Bolt length, nut or barrel geometry and usable engagement should be defined together. Crank fixing bolts and direct-mount chainring interfaces are separate requirements rather than automatic substitutes.

Can one quotation include pivots, hanger hardware and chainring fasteners?

Yes. The quotation can bring several hardware systems into one project while keeping each item’s identity and quantity clear. Mark which items are requested from PremFixer, which are supplied by another component partner and which appear only as mating references. A one-stop project still needs line-by-line scope, material, finish and revision information.

Do hardtail and full-suspension MTB models use the same kit?

No. A hardtail does not require the rear-suspension pivot kit used by a full-suspension frame. Other hardware may also vary with the frame, drivetrain and assembly configuration. We organise supply around the approved model BOM. Shared part numbers can be consolidated only when the documentation confirms that the same component and revision apply across the relevant models.

Can the hardware be made in aluminum, stainless steel or titanium?

These material families can be specified within the agreed manufacturing scope. Define the grade, condition, finish and finished requirements for each part. A material used in one location is not automatically suitable for another, and a different metal is not automatically an approved upgrade. Material changes should follow the project’s design approval and acceptance requirements.

Do you support prototypes and production quantities?

Yes. Prototype quantities, small batches and repeat production can be discussed for the project. State the quantity by part number and identify whether samples require the production finish and packing. Timing, tooling and manufacturing arrangements depend on the actual scope. Approval should distinguish individual part checks from the customer’s assessment of the relevant assembly or model.

Can you pack parts by model, subassembly or production station?

These grouping requirements can be specified and agreed with the order. Define the included items, quantities, revisions and label fields for each group. Supply may also be arranged by individual part number. Model-specific hardware does not automatically imply one retail bag per bike, and any customer-supplied or reference-only components should remain clearly excluded from the pack contents.

Does ISO certification mean every kit is approved for any MTB?

No. ISO 9001 concerns the quality management system within the certificate’s stated scope. It does not establish universal fit or vehicle-level performance. The drawings, material specifications, finished acceptance requirements and agreed validation responsibilities define the particular project. Our certificate page provides the original document for supplier assessment.

What should I send to start an MTB hardware quotation?

Send the drawings, sample information or BOM you currently have, with the model or project reference and required quantities. Mark the systems you need: pivots, hanger fixing, chainring mounting or other hardware. Draft information is welcome for an initial discussion. Required revisions, supply responsibilities and acceptance criteria are confirmed before manufacture is released.

Start with what you have

Send Your MTB Hardware BOM

Share your model or project reference, drawings or sample information, and required quantities. Tell us which hardware systems you need, and we will define the manufacturing and supply scope with you.
