What we supply.
Six sub-categories covering the wholesale bicycle drivetrain components your workshop replaces most often, plus the parts you sell as upgrade items. Whether you’re a bicycle drivetrain supplier for bike shops stocking wholesale bicycle groupsets or a bicycle drivetrain supplier for dealers building workshop reorder inventory, we’ve kept SKU breadth tight at launch (common speed counts and the brand ecosystems most shops genuinely service) rather than thin-stocking every niche variant.
Wholesale bicycle cassettes and freewheels
8 / 9 / 10 / 11 / 12-speed cassettes · Shimano HG, Shimano Microspline, SRAM XD/XDR, and Campagnolo freehub standards · Common ratios 11-28 through 11-50
Wholesale bicycle freewheels for 6, 7, and 8-speed legacy applications. Every SKU names the freehub standard and speed count so your parts manager confirms fit before the box arrives.
Wholesale bicycle chains
8 through 12-speed chains · Shimano, SRAM, KMC, and Connex compatibility · Hollow-pin on higher trim, standard pin on workshop-grade · Quick-link masterlinks supplied
Largely cross-compatible at the same speed count, with brand-specific exceptions flagged at quote stage (SRAM Flat-Top for 12-speed AXS, which we don’t supply).
Wholesale bicycle derailleurs
Front and rear derailleurs · Road and MTB across 8 through 12-speed · Mechanical only at launch · Cable-pull ratio matched to the shifter ecosystem
Electronic drivetrains (Di2, eTap AXS, EPS) outside launch scope. Mechanical wholesale bicycle derailleurs SKU-named for cable-pull standard (Shimano road, Shimano Dyna-Sys, SRAM) so they pair correctly.
Wholesale bicycle cranksets and chainrings
Single, double, and triple wholesale bicycle cranksets · Road and MTB · BCD specified per SKU (road 110mm/130mm, MTB direct-mount and generation-specific BCDs) · Replacement wholesale bicycle chainrings sold separately
Chainline specified per SKU so the buyer matches it to the crankset they’re servicing. Chainring tooth counts confirmed per quote.
Wholesale bicycle shifters
Mechanical road STI-style integrated brake-lever shifters · MTB trigger and grip-shift · 8 through 12-speed · Cable-pull ratios matched to derailleur ecosystem
Cable-pull ratio is the defining compatibility variable on wholesale bicycle shifters. Each SKU named for the derailleur ecosystem it pairs with.
Wholesale bicycle bottom brackets
Threaded BSA and Italian · Press-fit PF30, BB86, BB92, T47, and additional standards on request · Sealed cartridge bearings throughout
Wholesale bicycle bottom brackets are frame-specific; each SKU names its standard so the workshop confirms against the frame before ordering.
A B2B bicycle drivetrain supplier that knows compatibility is the whole game.
Ecosystem compatibility named on every SKU
Every wholesale drivetrain component on our catalog names the brand ecosystem (Shimano HG, Shimano Microspline, SRAM XD/XDR, Campagnolo, KMC, or other), the speed count, and the compatibility notes that matter (cable-pull ratio, hanger standard, freehub spline). As an international bicycle drivetrain supplier, we structure every SKU so a workshop manager doesn't have to email to ask whether a derailleur fits a specific bike.
Wholesale pricing that protects workshop margin
Direct-from-supplier wholesale drivetrain prices on the parts that drive workshop reorder revenue. Tier pricing improves as your volume grows. For a bicycle drivetrain supplier for retailers and bicycle drivetrain dealer suppliers, margin protection starts at the wholesale price.
Ryden-branded range + your-brand private label
We supply Ryden-branded wholesale bicycle drivetrain components; brand-name parts your customers ask for by name are quoted case by case. The Ryden range gives you margin headroom and a private-label offer for your shop's flagship builds. For bicycle drivetrain wholesalers and bicycle groupset suppliers, that covers both customer types.
Fast reorder turnaround for service stock
Wholesale bicycle drivetrain reorders are typically smaller and more frequent than bike orders. A workshop runs out of 11-speed chains on a Tuesday and needs them by the following Monday. Standard reorder SKUs dispatch in around 2 weeks, and longer-lead items are quoted honestly per SKU.
Your brand on the parts your workshop fits every day.
A private-label drivetrain range gives your shop two commercial advantages over reselling brand-name parts only. First, margin: branded wholesale bicycle chains, wholesale bicycle cassettes, and wholesale bicycle chainrings carry margin a workshop can’t extract from resale parts. Second, customer retention: a customer who’s had your shop’s branded chainring fitted twice is harder to lose to the box-store competitor offering Shimano at 5% under your price.
We extend custom bicycle drivetrain components across chains, cassettes, chainrings, cranksets, and derailleurs at 200 units per SKU, with 3 weeks to first sample and 2–3 months from sample approval. Shifters and bottom brackets are technical enough that private label isn’t viable at launch volumes; we’ll flag that honestly if you ask rather than overpromise.

Wholesale bicycle drivetrains are the cycling component category where “compatibility” isn’t a feature, it’s the whole product. The wrong wholesale bicycle cassette, chain, or derailleur for an ecosystem doesn’t just underperform, it doesn’t function. Our SKUs name the specifications that determine fit, so your workshop’s parts manager can confirm compatibility before placing the order rather than after.
Speed count
8, 9, 10, 11, and 12-speed wholesale bicycle drivetrain components across the range. Each SKU specifies its speed count, because chains, cassettes, derailleurs, and shifters from different speed counts are not interchangeable. 11-speed and 12-speed in particular are tight tolerances; mixing across speed counts on a single drivetrain creates shifting problems that aren’t repairable.
Brand ecosystem
Shimano HG (the standard freehub for most Shimano cassettes through 11-speed), Shimano Microspline (Shimano’s 12-speed MTB freehub), SRAM XD and XDR (SRAM’s 11 and 12-speed freehubs), and Campagnolo (Campagnolo’s freehub standard for their cassettes). The freehub on the wheel determines which wholesale bicycle cassettes fit; the chain and derailleur ecosystem determine which wholesale bicycle shifters work. Each SKU on our wholesale drivetrain catalog names the ecosystem it’s built for.
Cable-pull ratio
Mechanical wholesale bicycle derailleurs and wholesale bicycle shifters work because the cable pull on the shifter matches the cable pull required by the derailleur. Shimano road, Shimano MTB (post-Dyna-Sys), and SRAM each use different cable-pull ratios that aren’t interchangeable across brands. The SKUs name the cable-pull ratio standard so your workshop knows which shifter pairs with which derailleur before the box arrives.
Hanger standard
Derailleur hangers attach the rear derailleur to the frame; they’re frame-specific and break in crashes. We stock replacement hangers for the most common frame standards, named by Wheels Manufacturing reference number, with the frame brands and models each hanger fits. Hangers are a small-margin high-attachment-rate item; a workshop that doesn’t carry them sends customers to the competitor that does.
Chainring BCD and chainline
Wholesale bicycle cranksets and replacement wholesale bicycle chainrings specify bolt circle diameter (BCD) and intended chainline. Common road BCDs are 110mm and 130mm; MTB direct-mount and various BCDs depending on crankset generation. Each SKU names its BCD and chainline so the buyer matches it to the crankset they’re servicing.
Bottom bracket standards
Threaded BSA (the most common standard), Italian (a narrower threaded standard on some Italian-made frames), and press-fit standards (PF30, BB86, BB92, T47, and others) depending on the frame the workshop is servicing. Each wholesale bicycle bottom bracket SKU specifies its standard.
Electronic shifting groupsets (Shimano Di2, SRAM eTap AXS, Campagnolo EPS) aren’t in our wholesale drivetrain catalog at launch. Electronic drivetrain components require ecosystem-specific software updates, battery management, and direct service relationships with the brand that don’t fit a third-party wholesale model at launch volumes. Single-speed and fixed-gear drivetrain components are also outside launch scope, a separate enthusiast category we’d rather build properly when we move into it. Internal gear hubs (Shimano Alfine, Rohloff, Sturmey-Archer) are outside scope at launch because they’re a different product category with different service requirements.
Wholesale bicycle drivetrains ship like parts, get fitted like specialist work.
Freight is the lowest per-SKU of any wholesale category we supply
Wholesale bicycle drivetrain components are dense and small relative to bike freight. A wholesale bicycle cassette weighs more than a saddle but takes up a fraction of the box volume. Per-SKU freight is the lowest of any wholesale category we supply, and small-volume reorders can move by parcel courier rather than pallet for fast turnaround. For bicycle drivetrain distributors and commercial bicycle drivetrain suppliers ordering bulk bicycle drivetrains, the freight economics are the most favorable in our catalog. International freight from the origin port is quoted per shipment alongside your initial quote. For workshops setting up ongoing service inventory, we can quote standing-order arrangements at agreed reorder intervals.
Packing comes in retail-ready or workshop-ready tiers, your choice
Wholesale bicycle drivetrain components ship in retail-ready packaging where they're sold through to end customers (wholesale bicycle chains in branded boxes, wholesale bicycle cassettes in blister packs or boxes depending on the SKU), or in workshop-ready bulk packaging where the workshop fits them directly to bikes. Quote stage confirms which packaging tier you need; the choice affects unit cost and how your shop displays or stocks the part.
Tool requirements named at the SKU level
Wholesale bicycle drivetrain components fit standard workshop tooling for the most part. Where a specific tool is required (12-speed chain quick-link pliers for some chain standards, freehub-specific cassette tools for SRAM XD versus Shimano HG), we name the tool in the SKU notes so your workshop doesn't discover the requirement at fit time. For workshops without a specific tool, our tools and workshop wholesale range carries what fits our wholesale drivetrain SKUs.

What buyers actually ask about wholesale bicycle drivetrains.
Do you supply Shimano, SRAM, and Campagnolo branded parts as wholesale resale?
We supply Ryden-branded wholesale bicycle drivetrain components; brand-name parts (e.g. Shimano, SRAM, Campagnolo) are quoted case by case.
What speed counts do you supply for wholesale bicycle drivetrains?
8, 9, 10, 11, and 12-speed wholesale bicycle drivetrain components across wholesale bicycle cassettes, wholesale bicycle chains, wholesale bicycle derailleurs, and wholesale bicycle shifters. Confirmed per SKU which ecosystems are available at each speed count.
Do you supply Shimano Microspline or SRAM XD/XDR wholesale bicycle cassettes?
Yes for both, in the cassette ratios our supplier base carries. Microspline is Shimano’s 12-speed MTB freehub standard; XD and XDR are SRAM’s 11 and 12-speed freehub standards. Specific cassette ratios are confirmed per quote. The workshop reorder SKUs (most-common 11-50 and 10-50 MTB ratios) carry through, and rarer ratios may sit on longer lead times.
What’s the difference between Shimano HG and the newer freehub standards?
Shimano HG is the standard freehub used by most Shimano wholesale bicycle cassettes through 11-speed and remains the most common standard a workshop services. Shimano Microspline appeared for 12-speed MTB; SRAM XD and XDR cover SRAM’s 11 and 12-speed cassettes. The wheel’s freehub determines which cassettes will physically fit; we name the freehub standard on every wholesale bicycle cassette SKU so the buyer doesn’t have to cross-reference.
Do you supply electronic shifting components (Di2, eTap, EPS)?
Not at launch. Electronic drivetrain components require ecosystem-specific software updates, battery management, and direct service relationships with the brand that don’t fit a third-party wholesale model at launch volumes. We’ll revisit when the right brand relationships are in place.
Do you supply derailleur hangers?
Yes. Replacement hangers for the most common frame standards, named by Wheels Manufacturing reference number, with the frame brands and models each hanger fits. Hangers are a high-attachment-rate item for any service-focused shop; a workshop that doesn’t carry them sends customers to the competitor that does.
What’s the MOQ on wholesale bicycle drivetrain parts versus complete bikes?
Substantially lower. Wholesale drivetrain components run at MOQs that make sense for workshop reorder cycles, typically 50 units per SKU depending on the part, with wholesale bicycle chains and wholesale bicycle cassettes running tighter than wholesale bicycle cranksets and wholesale bicycle shifters. Confirmed per category in your quote.
What’s the lead time on a standard reorder for wholesale bicycle drivetrains?
Stock catalog wholesale bicycle drivetrain components typically dispatch in around 2 weeks. Private-label production runs to the standard 2–3 months from sample approval timeline. Mixed orders carry both lead times honestly in the quote.
What wholesale bicycle chains do you supply and are they compatible across brands?
Wholesale bicycle chains in 8 through 12-speed from Shimano, SRAM, KMC, and Connex ecosystems where our supply chain supports them. Chains are largely cross-compatible at the same speed count (an 11-speed KMC chain runs on a Shimano or SRAM 11-speed drivetrain), with brand-specific exceptions like SRAM Flat-Top chains for 12-speed AXS, which require the matching cassette and chainrings. We don’t supply Flat-Top chains, and we flag the brand-specific exceptions at quote stage.
Do you supply chain breakers and quick-link pliers?
Not in this wholesale bicycle drivetrain category, but they sit naturally in the wholesale tools and workshop range. The tools that fit our wholesale drivetrain SKUs are stocked alongside the parts so a first-time drivetrain stocker can quote both at once.
Can you supply a starter inventory of wholesale bicycle drivetrains for a new shop?
Yes. Quote stage confirms a starter inventory across wholesale bicycle drivetrain components based on your shop’s target customer mix (road, MTB, mixed) and your service capacity. The order pattern field on the form flags this so the reply structures appropriately, since a sample-first starter quote looks different from an ongoing-reorder quote.
What’s the warranty on wholesale bicycle drivetrain parts?
Wholesale bicycle drivetrain components are wear items. Warranty covers manufacturing defect rather than wear, and the warranty period is shorter than for frames and frame components: 12 months against manufacturing defect on wholesale bicycle chains, cassettes, chainrings, cranksets, derailleurs, and shifters; wear from use is not covered. Confirmed in your quote.
Do you supply complete bicycle groupsets wholesale or only individual components?
Both. Complete bicycle groupsets wholesale are available as matched sets (cassette, chain, crankset, derailleurs, shifters, and bottom bracket in a single order at a single speed count and brand ecosystem). Individual wholesale bicycle drivetrain components are also available for workshops that need to restock specific parts rather than full groupsets. Most bicycle drivetrain wholesalers and bicycle groupset suppliers order a mix of both.
How do I open a bicycle drivetrain wholesale account?
Two paths. Single-category quotes don’t require an account. Apply for a bicycle drivetrain wholesale account when you want ongoing supply, access to the full wholesale drivetrain catalog, and tier pricing across all component categories. The application takes 2 business days to process. Most bicycle drivetrain distributors and bicycle drivetrain dealer suppliers start with a single quote and apply for a full account after the first order lands.
Do you offer a wholesale drivetrain catalog or price list?
We don’t publish a static wholesale drivetrain catalog with fixed prices because wholesale drivetrain prices vary by volume, destination, component mix, and brand ecosystem. Your quote is your bicycle drivetrain wholesale catalog: it contains the SKUs available, specs, compatibility notes, unit cost at your volume, MOQ, and lead time.
Can I get custom bicycle drivetrain components with my own branding?
Yes, across chains, cassettes, chainrings, cranksets, and derailleurs at 200 units per SKU. Shifters and wholesale bicycle bottom brackets are technical enough that private label isn’t viable at launch volumes. Custom bicycle drivetrain components carry 3 weeks to first sample and 2–3 months from sample approval.
What wholesale bicycle transmission parts do you supply beyond the six main categories?
Derailleur hangers for the most common frame standards, replacement cables and housing (in our cables category), and the tools that fit our wholesale bicycle drivetrain SKUs (in our tools and workshop category). The wholesale bicycle transmission parts ecosystem extends across these adjacent categories so a workshop can source everything from a single supplier.
