Wholesale Bicycle Workshop Consumables Suppliers: the parts that don’t get their own page but still complete the service.
Wholesale workshop consumables and accessory parts for shops worldwide. Cables and housing, derailleur hangers, headsets and bearings, bottle cages, seatpost clamps, and the smaller parts every service department reorders to finish the job. Honest about the category: these aren’t flagship products, they’re the parts that complete the rest. From varies by sub-category; pack-tier minimums match workshop usage.

- Honest scope, not padded inventory
What we supply.
Six sub-categories of workshop consumables and accessory parts. These are the items that complete service work and that workshops reorder regularly but that don’t have the product depth or buyer audience to warrant dedicated pages of their own. We’ve kept SKU breadth focused on the items workshops genuinely run through, not on padding the catalog with adjacent items we can’t supply at workshop reorder volumes.
Cables and housing
Stainless shift cables (1.1mm and 1.2mm) and brake cables (1.5mm and 1.6mm) · Housing in 4mm shift OD and 5mm brake OD · Standard colors with selected colors on higher trim · End caps and ferrules supplied
The volume consumable that pairs with mechanical drivetrain and rim/mechanical-disc brakes. Brand-specific cable end fittings supplied where applicable (Shimano barrel end vs SRAM ends).
Derailleur hangers
Replacement hangers for the most common frame standards · Named by Wheels Manufacturing reference number · Available individually or in starter inventory packs
Hangers bend in crashes and break in worse crashes. A small-margin high-attachment-rate item that any service-active shop carries. Frame brand and model named per SKU.
Headsets and headset bearings
Threadless headsets in 1-1/8" straight, 1-1/4" tapered upper, 1-1/2" tapered lower · Sealed cartridge bearings · Internal-cup and external-cup variants
Replacement bearings supplied separately for service work. The consumable that pairs with frame service and crash-replacement work.
Bottle cages and accessories
Aluminium and composite cages in standard widths · Side-entry and top-entry profiles · Mounting hardware supplied · Bottle cage adapters for non-standard frame mounts
Fits the international standard bottle cage mount (two M5 bolts spaced 64mm apart). Standard 73mm × 200mm bottle dimensions.
Seatpost clamps
Quick-release and bolted clamps · Standard seat tube outside diameters: 28.6mm, 31.8mm, 34.9mm, 36.4mm, and less common sizes · Sized to fit the seat tube OD not the seatpost OD
Wears, gets damaged in mishandling, gets replaced as part of frame service work. Mismatch between clamp and seat tube doesn’t work.
Small parts and fasteners
Chainring bolts, derailleur cable bolts, brake lever bolts, headset spacers, bar end plugs, cable end caps and ferrules · Standard metric sizes (M5, M6, M8) · Available individually or in workshop-bulk quantities
Not a flagship category but a real reorder item for shops that maintain a small-parts inventory. Standard steel hardware; specialty titanium and aluminium fasteners outside launch scope.
A supplier that recognizes consumables matter for what they enable, not what they cost.
One supplier for the consumables that complete other categories
Where you already source drivetrain, brakes, wheels, and bikes through us, the workshop consumables that complete service work on those categories are available through the same supplier relationship. One quote relationship, one shipment consolidation, one set of payment terms across the consumables that pair with the rest of your catalog.
Wholesale pricing that protects workshop margin
Direct-from-supplier wholesale pricing on parts that are commercially modest individually but matter at workshop reorder volume. Tier pricing improves as your volume grows.
Starter inventory packs for new shops
New shops setting up their first parts inventory often need starter packs across the consumable categories: a sample of derailleur hangers across common frame standards, a starter cable and housing range, a small-parts box with the fasteners and accessories that service work requires. Available at quote stage.
Reorder pack sizes that match workshop usage
Cables, housing, hangers, and small parts ship in pack sizes that match workshop usage. We don’t force you to order 1,000 cable end caps when you’ll use 50 in a quarter, and we don’t force you to order single hangers when you need a starter range across five frame standards.
Branded consumables, where they make commercial sense.
Workshop consumables vary in their private-label viability. Some sub-categories work well for private label: cables and housing in your shop’s color, branded bottle cages that appear on customer bikes, branded seatpost clamps that show on a customer’s bike floor. Other sub-categories don’t work well: derailleur hangers are frame-specific and the buyer (a customer or workshop ordering a replacement) wants the correct hanger for their frame, not a branded one. Small parts and fasteners are commodity items where private label adds no commercial value.
We’re honest about the split: private label across cables and housing, bottle cages, and seatpost clamps at [200 units per SKU for cables, housing, bottle cages, and seatpost clamps], with 3 weeks to first sample and 2–3 months from sample approval. Derailleur hangers, headsets, and small parts remain commodity supply.
Enquire about private-label consumablesSpecs that matter for parts that complete other parts.
Workshop consumables are the parts that complete service work on the larger drivetrain, brake, and frame components. Their specifications matter not because the consumables themselves are flagship products, but because the wrong consumable for the larger component creates the service problem the workshop is trying to solve. The specs that matter:
Cables and housing: diameters and brand compatibility
Mechanical shift cables use 1.1mm or 1.2mm stainless steel cable (1.2mm is the post-Shimano-Dyna-Sys standard; 1.1mm is the legacy standard); mechanical brake cables use 1.5mm or 1.6mm cable. Shift housing is 4mm outside diameter (the 4mm SP41 standard); brake housing is 5mm outside diameter. The housing has to match the cable diameter and the brand of the shifter or brake lever it terminates at: Shimano shift cables have a standard barrel end fitting that matches Shimano shifter cable mounts; SRAM cable ends are slightly different and brand-specific in some cases. Every cable and housing SKU names the cable diameter, the cable end fitting type, and the brand compatibility.
Cables and housing: internal versus external routing
Most cables and housing in our launch range are designed for external (frame-exterior) routing, the standard for most aluminium and entry-trim road, MTB, and commuter bikes. Internal routing housing(designed for routing through the frame’s interior) is available on selected SKUs for shops servicing higher-trim bikes that use internal cable routing. Internal routing housing typically has a smoother exterior coating and tighter fitting profiles. Each SKU names whether it’s external or internal routing standard.
Derailleur hangers: frame standard naming
Derailleur hangers are frame-specific. There are hundreds of hanger profiles across the bicycle industry, and naming them accurately requires a reference system. Most workshop suppliers use the Wheels Manufacturing numbering system (hangers numbered 1 through 500+ corresponding to specific frame standards). We catalog hangers by Wheels Manufacturing number or equivalent reference, and each hanger SKU names the frame brands and models the hanger fits. Replacement hangers are typically supplied as the bare hanger plus the standard mounting bolts.
Headsets: size standards
Headsets are frame-specific to size. The most common modern standards are 1-1/8" straight (the standard threadless headset for most aluminium road, MTB, and commuter bikes), 1-1/4" tapered upper (for tapered-steerer frames common on higher-trim road and gravel bikes), and 1-1/2" tapered lower (the lower bearing on tapered-steerer frames). Each headset SKU names the upper and lower bearing diameter. Headsets ship as complete units (top cap, top spacer, upper bearing, lower bearing, bottom spacer, lower seal) or as individual replacement bearings for service. The bearing diameter and sealing standard are named per SKU.
Bottle cages: bottle and frame compatibility
Bottle cages fit standard bottle dimensions (most modern water bottles are roughly 73mm diameter and 200mm tall). Most cages mount to the frame via two standard M5 bolts spaced 64mm apart (the international standard bottle cage mount). Some frames use proprietary mounting standards (rare and named per SKU); our cages are designed for the standard mount unless otherwise stated.
Seatpost clamps: seat tube diameter
Seatpost clamps fit the outside diameter of the seat tube on the frame, not the inside diameter (which is the seatpost diameter). Common seat tube outside diameters: 28.6mm, 31.8mm, 34.9mm, 36.4mm, and several less common sizes. Each clamp SKU names the seat tube outside diameter it fits. Mismatch between clamp and seat tube doesn’t work: too small a clamp won’t fit; too large a clamp won’t tighten properly.
Small parts and fasteners: bolt standards and dimensions
Cycling fasteners use standard metric sizes (M5, M6, M8 most commonly) with specific lengths and head profiles per application. Chainring bolts (M8 with specific head designs that match crank arm designs), derailleur cable bolts (M5 typically), brake lever bolts (M5 typically). Each small-parts SKU names the bolt size, length, and intended application.
Headset spacers and bar end plugs
Headset spacers (cylindrical aluminium or composite spacers that fit between the headset top cap and the stem) come in standard 1-1/8" inside diameter with thicknesses from 2mm to 20mm. Bar end plugs (the plugs that finish the ends of drop bars and flat bars) fit standard 22.2mm bar end diameter or 23.8mm drop bar end diameter. Both are commodity items in standard sizes.
Specialty cables and housing (Compressionless brake housing for elite road racing, electronic-shift wiring harnesses) are outside scope. Specialty hangers for niche frame standards (some older or proprietary frames) are outside scope. Sealed bearing tools and headset press tools are on the workshop tools range rather than as consumables. Specialty bolt kits in titanium or aluminium for weight-conscious applications are outside launch scope; we supply standard steel hardware.
Small parts ship dense and fit on the same shipment as bigger orders.
The densest wholesale category we supply, parcel-eligible for solo reorders
Workshop consumables are the densest wholesale category we supply. A box of cable housing, derailleur hangers, headset bearings, and small parts takes a fraction of the freight footprint of any complete-bike or wheelset category. Per-SKU freight is minimal, and most consumable reorders move by parcel courier rather than pallet. International freight from the origin port is quoted per shipment alongside your initial quote. Consumable orders that ship alongside larger drivetrain, brake, or wheel orders consolidate onto a single shipment, which reduces freight cost compared to ordering separately.
Retail-ready or workshop-bulk packing per SKU
Consumables ship in retail-ready packaging where they’re sold through to end customers (carded or boxed depending on the SKU), and in workshop-bulk packs where the workshop fits them directly. Cables and housing ship on coils or in cut lengths depending on the order. Derailleur hangers ship individually or in starter inventory packs. Small parts ship in compartmentalized boxes for workshop inventory or in individual retail packaging.
Tools follow consumables: hanger alignment, cable cutters, headset press
Consumables installation requires the standard tools for each sub-category. Cable and housing installation requires cable cutters and end-cap pliers. Derailleur hanger replacement requires the standard Allen keys plus a hanger alignment tool for verification after installation. Headset installation requires headset press tools for first-time installation and a star nut setter; replacement bearing service uses standard bearing pullers. The workshop tools range is the natural attachment for shops setting up consumable inventory because the tools and consumables get sourced together.

What buyers actually ask.
What cable and housing standards do you supply?
Mechanical shift cables in 1.1mm and 1.2mm diameters (1.2mm is the post-Shimano-Dyna-Sys standard; 1.1mm is the legacy standard); mechanical brake cables in 1.5mm and 1.6mm. Housing in 4mm shift OD and 5mm brake OD, in standard colors (black across the range, plus selected colors on higher trim). Brand-specific cable end fittings (Shimano barrel ends, SRAM ends) supplied where applicable. Each SKU names the cable diameter, end fitting type, and brand compatibility.
Do you supply derailleur hangers for specific frame brands?
Yes. We catalog hangers by Wheels Manufacturing reference number (or equivalent) and name the frame brands and models each hanger fits in the SKU description. Available individually or as starter inventory packs across common frame standards. Hangers ship as the bare hanger plus the standard mounting bolts.
What headset sizes do you stock?
1-1/8" straight (the volume standard for aluminium and entry-trim bikes), 1-1/4" tapered upper, and 1-1/2" tapered lower (the standards for tapered-steerer frames). Each headset SKU names the upper and lower bearing diameters. Headsets ship as complete units or as individual replacement bearings for service work.
Do you supply just bottle cages or also bottle cage adapters?
Both. Bottle cages in aluminium and composite construction in standard widths fitting standard bottle dimensions (73mm diameter, 200mm tall), plus bottle cage adapters for frames without standard mounting bolt patterns. The standard cage mount is two M5 bolts spaced 64mm apart.
What seat tube diameters do your seatpost clamps fit?
28.6mm, 31.8mm, 34.9mm, 36.4mm, and several less common sizes. Confirmed per SKU. Seatpost clamps fit the OUTSIDE diameter of the seat tube on the frame, not the inside diameter (which is the seatpost diameter). Mismatch between clamp and seat tube doesn’t work.
Do you supply small parts and fasteners individually?
Yes. Chainring bolts (M8 with specific head designs that match crank arm designs), derailleur cable bolts (M5 typically), brake lever bolts (M5 typically), headset spacers (1-1/8" ID, 2-20mm thicknesses), bar end plugs (22.2mm flat bar or 23.8mm drop bar end), cable end caps, and ferrules. Available individually or in workshop-bulk quantities for shops maintaining small-parts inventory.
Do you supply Compressionless brake housing or electronic-shift wiring?
Not at launch. Specialty Compressionless housing for elite road racing and electronic-shift wiring harnesses are outside our launch scope; the supply chains are too narrow at our launch volumes to justify the SKU range.
What’s the warranty on workshop consumables?
Manufacturing-defect coverage on cables, housing, hangers, headsets, and other consumables: [12 months from dispatch on manufacturing defects]. Wear isn’t covered (consumables are wear items by definition). The honest answer: defect coverage yes, wear coverage no. Confirmed per SKU in your quote.
Can you supply a starter consumables inventory for a new shop?
Yes. Quote stage confirms a starter inventory based on your shop’s service capability and customer mix: cable and housing starter range, derailleur hanger starter pack across common frame standards, headset selection across the volume sizes, bottle cage and seatpost clamp range, and a small-parts box with the commodity fasteners service work requires. The "starter inventory for a new shop" option on the order pattern field flags this routing in the reply.
Can consumable orders ship alongside larger drivetrain, brake, or wheel orders?
Yes, and this is the key commercial mechanism for this category. Consumables consolidate onto larger shipments where the larger order is also being placed, which reduces freight cost compared to ordering consumables separately. The "add-on to a larger order" option on the order pattern field flags this; quote stage confirms the consolidation structure based on your other open orders.
Why isn’t there a dedicated page for cables and housing?
Cables and housing genuinely are a substantial sub-category, but they don’t have the specialist buyer audience or product-depth distinction that would justify a dedicated deep-dive page. They live here as a sub-category of workshop consumables because that’s the genuine buyer journey: workshops ordering cables typically order other consumables in the same shipment.
What’s the relationship between this page and the other parts category pages?
This page covers the smaller consumables that complete service work on the parts categories with dedicated pages. The dedicated pages (drivetrain, brakes, wheels and tires, frame and cockpit, saddles, bars and stems, pedals and cleats, chains and cassettes) cover their full categories at depth. This page covers what’s left: the consumables that finish those categories’ service work and that have real workshop reorder demand but don’t warrant pages of their own.
