What we supply.
Two product categories that wear together, replaced together, and reorder together in any service-active workshop. We’ve structured our chain and cassette supply around the consumable reorder cadence rather than treating them as individual drivetrain components: pair pricing, matched compatibility quoting, and standing-order arrangements that reflect the genuine drivetrain wear cycle.
Chains, 8 and 9-speed
Volume chains for legacy and entry-trim drivetrains · Hollow-pin and solid-pin options · Cross-compatible across Shimano, SRAM, KMC · Quick-link masterlinks supplied
The category that covers older bike service work and entry-trim new bike fitments. Workshop-grade solid-pin remains the volume choice here.
Chains, 10-speed
10-speed chains across Shimano, SRAM, and KMC ecosystems · Hollow-pin on higher trim, solid-pin on workshop-grade · Quick-link masterlinks supplied
10-speed remains common on mid-trim road and MTB bikes. Mid-volume reorder cadence for service-active workshops.
Chains, 11-speed
11-speed chains across Shimano, SRAM (non-Flat-Top), KMC, and Connex ecosystems · Hollow-pin construction across most SKUs
The volume category for current-generation road and MTB drivetrains. Largely cross-compatible at the same speed count across major brand ecosystems.
Chains, 12-speed
12-speed chains across Shimano MTB, SRAM Flat-Top (AXS road and T-Type MTB), KMC, and Connex · Flat-Top compatibility named per SKU because mixing 12-speed standards is the common quote-stage error
Flat-Top chains require Flat-Top-specific cassettes and chainrings. A Flat-Top chain doesn’t work on a standard 12-speed drivetrain, and vice versa.
Cassettes, Shimano HG ecosystem
Fits Shimano HG freehubs across 8 through 11-speed · Ratios from 11-28 to 11-50 depending on speed count · Hyperglide tooth profile
The volume freehub standard for road and most MTB through 11-speed. Ratios named per SKU; ratio range named by customer base in your quote.
Cassettes, Shimano Microspline ecosystem
Fits Shimano Microspline freehubs (Shimano 12-speed MTB standard) · Ratios from 10-45 to 10-51
Microspline-specific tooth profile. The Shimano 12-speed MTB cassette ecosystem; matches the 12-speed Shimano MTB drivetrains.
Cassettes, SRAM XD ecosystem
Fits SRAM XD freehubs (SRAM 11-speed MTB and some 12-speed) · Ratios from 10-42 to 10-52 · XD-specific spline pattern
The volume SRAM MTB freehub standard. Wider ratios than Shimano HG accommodate 1x MTB drivetrains without front derailleurs.
Cassettes, SRAM XDR ecosystem
Fits SRAM XDR freehubs (SRAM 12-speed AXS road and some MTB) · XDR is XD with a wider freehub body to accommodate the wider 12-speed road cassette
XDR-specific freehub. Different from XD despite the naming similarity; the wider body is the distinguishing dimension.
Cassettes, Campagnolo ecosystem
Fits Campagnolo freehubs across the Campagnolo speed range · Distinct freehub spline pattern from Shimano and SRAM
Niche supply at launch volumes. Confirmed per quote based on demand and your target market. Campagnolo is a smaller portion of our supply chain.
A supplier that treats chains and cassettes as the consumable pair they are.
Pair pricing on chain-cassette combinations
Where you source chains and cassettes together on matched ecosystem and speed-count combinations, we structure quote pricing around the pair rather than each part separately. A workshop fitting a customer’s drivetrain replacement orders the pair; the pricing acknowledges that pattern.
Standing-order arrangements for ongoing workshop reorder
Drivetrain consumable reorders are predictable on a service-active workshop cycle: chains and cassettes wear together, replacement happens at workshop service intervals, and reorder cadence follows the shop’s customer base. Standing-order arrangements at agreed reorder intervals reduce the friction of repeat ordering for shops with consistent reorder demand.
Brand resale + your-brand private label
Brand-name chains and cassettes (Shimano, SRAM, KMC, Connex, Campagnolo where supplied) alongside our Ryden-branded chain and cassette range. The Ryden range gives margin headroom on the highest-volume consumables in the drivetrain category, particularly on chains where customers don’t shop by brand the way they shop derailleurs by brand.
Ecosystem compatibility named per SKU
Every chain SKU names the speed count and ecosystem compatibility. Every cassette SKU names the freehub body, speed count, and ratio range. A workshop manager confirms compatibility before placing the order rather than discovering it after.
Your brand on the drivetrain consumables your shop replaces most.
Chains and cassettes are among the strongest private-label candidates in the parts catalog after brake pads and saddles, and for the same underlying reason: customers don’t shop these by brand the way they shop derailleurs and shifters by brand. A customer asking your workshop to fit a new chain doesn’t ask which brand of chain; they ask which chain fits their drivetrain and how long it lasts. Your shop’s branded chain on a customer’s bike for the second or third replacement cycle becomes the chain they ask for by your shop’s name.
We extend private label across chains and cassettes at [300 units per chain SKU; cassette PL launch covers Shimano HG and Microspline], with 3 weeks to first sample and 2–3 months from sample approval. Private-label chains run across 8 through 12-speed; private-label cassettes run across Shimano HG and Shimano Microspline ecosystems at launch, with SRAM XD and XDR additions planned in [2026 Q4].
Enquire about private-label chains and cassettesThe compatibility variables that determine fit, and the wear-pair logic that determines reorder.
Chains and cassettes are the drivetrain components where compatibility and wear interact more than any other parts category. A chain that’s the wrong speed count doesn’t engage the cassette correctly; a cassette that fits the wrong freehub doesn’t mount; a worn chain ruins a fresh cassette by accelerating its wear. The specifications and wear logic together determine what a workshop orders.
Speed count
Chains and cassettes must match each other and the rest of the drivetrain. 8-speed chains and cassettes work with 8-speed shifters, derailleurs, and cranksets; 11-speed components require 11-speed chains and cassettes; 12-speed requires 12-speed. Mixing speed counts across components produces shifting that doesn’t work, and at higher speed counts (11 and 12) the tolerances are tight enough that even minor mismatches degrade performance. Every chain and cassette SKU names its speed count explicitly.
Brand ecosystem and cross-compatibility (chains)
Chains are largely cross-compatible across major brand ecosystems at the same speed count. An 11-speed KMC chain works on a Shimano 11-speed drivetrain, on a SRAM 11-speed drivetrain (excluding SRAM Flat-Top systems), and on a Campagnolo 11-speed drivetrain. The exceptions matter: SRAM Flat-Top chains(used in SRAM AXS road and T-Type AXS MTB 12-speed systems) require the matching SRAM Flat-Top cassette and chainrings; a Flat-Top chain doesn’t work on a standard 12-speed drivetrain, and a standard 12-speed chain doesn’t work on a Flat-Top drivetrain. We name Flat-Top chain SKUs explicitly to avoid the most common cross-compatibility error.
Freehub body compatibility (cassettes)
The freehub body on the rear wheel hub determines which cassettes will physically fit. Shimano HG is the volume freehub standard through 11-speed. Shimano Microspline is required for 12-speed Shimano MTB cassettes. SRAM XD covers 11-speed SRAM MTB cassettes and some 12-speed. SRAM XDR covers 12-speed SRAM AXS road and some MTB cassettes (XDR is XD with a wider freehub body to accommodate the wider 12-speed road cassette). Campagnolo has its own freehub standard for Campagnolo cassettes. Every cassette SKU names the freehub body it fits.
Cassette ratio range
Cassette ratios are expressed as smallest cog to largest cog (for example, 11-28, 11-32, 11-34, 11-46, 10-50, 10-52). Smaller ratio range (11-28) is for road riding with relatively flat terrain; wider ratio range (11-34, 11-46) accommodates climbing and varied terrain; very wide ratio range (10-50, 10-52) is the MTB 1x12 standard for steep climbing without a front derailleur. The ratio range you stock depends on your customer base. Each cassette SKU names its ratio range.
Chain construction: hollow pin versus solid pin
Higher-trim chains use hollow-pin construction (the chain pins are drilled through, reducing weight). Workshop-grade chains use solid-pin construction (slightly heavier but more durable in extended use). Hollow-pin chains carry a small weight saving and a small price increase; solid-pin chains carry a small durability advantage. The choice is workshop-determined and the SKU spec sheet names which construction applies per chain.
Quick-link masterlinks
Modern chains include a quick-link masterlink that allows tool-free chain removal and refitment for service. SRAM and KMC chains include their respective quick-link systems; Shimano 11 and 12-speed chains use the Quick-Link masterlink. Each chain SKU ships with the appropriate masterlink. Replacement masterlinks are available as a separate consumable for shops that lose them during service.
Chain wear and cassette wear together (the pair logic)
Chains stretch with use: the pins and inner plates wear, lengthening the chain over thousands of kilometers. A stretched chain wears the cassette cogs by riding on them at a slightly different angle than the unworn chain did. The consequence: a fresh chain fitted to a worn cassette skips under load (because the cog teeth are shaped to the worn chain); a worn chain fitted to a fresh cassette wears the fresh cassette rapidly. The practical workshop rule: chain and cassette get replaced together once the chain reaches roughly 0.75% stretch. This is why chains and cassettes are a consumable pair and why pair pricing reflects how they actually reorder.
Chain wear measurement tools
Chain wear is measured with a chain wear gauge (a specialized tool that fits between chain links to measure stretch). Most workshops measure customer chain wear at every service to determine whether the chain needs replacement; the workshop tools range carries chain wear gauges across the major standards. Customers without a wear gauge typically replace at fixed kilometer intervals or visible wear signs.
Electronic shifting groupset chains and cassettes are part of the broader electronic drivetrain category that’s outside our launch scope. Shimano Di2 12-speed cassettes (where they have specific Di2-only variants) and SRAM AXS-specific cassettes ship as part of the closed AXS supply chain that we don’t access at launch volumes. Single-speed and fixed-gear chains and cogs are outside scope. Track-specific chains (used on velodrome track bikes with their own dimensional standards) are outside scope.
Dense to ship, simple to service.
Freight is the lowest per-SKU of any wholesale category we supply
Chains and cassettes ship dense relative to other drivetrain components. A box of chains takes a fraction of the freight footprint of cranksets or wheels; cassettes ship denser still. Per-SKU freight is among the lowest of any wholesale category we supply alongside pedals and cleats. Small-volume reorders move by parcel courier for fast turnaround on workshop stockouts, particularly important for chain reorders when a service-active workshop runs out of a specific speed count and ecosystem combination. International freight from the origin port is quoted per shipment alongside your initial quote.
Retail-ready or workshop-bulk: choose at quote stage
Chains ship in retail-ready packaging where they’re sold through to customers (branded boxes with the masterlink, lubricant guidance, and installation notes) and in workshop-bulk packs (multiple chains without retail packaging) where the workshop fits them directly. Cassettes ship in retail-ready boxes or in workshop-bulk packs. Quote stage confirms packaging tier per SKU and tier.
Tool requirements split by chain ecosystem and cassette freehub
Chain installation requires a chain breaker tool to size the chain to the bike’s chainstay length, and a quick-link tool (or pliers) to engage the masterlink. Some quick-link standards require specific pliers (Shimano Quick-Link in particular has its own engagement procedure); we name the tool requirement per chain SKU. Cassette installation requires a cassette tool specific to the freehub standard (Shimano HG, Microspline, SRAM XD, XDR, Campagnolo each use distinct cassette removal tools) and a chain whip to hold the cassette while removing the lockring. The workshop tools range carries cassette tools across all the freehub standards we supply for. Cassette installation torque on the lockring is a standard specification (typically 40 Nm); we supply the torque chart per cassette SKU.

What buyers actually ask.
Are chains cross-compatible across brand ecosystems at the same speed count?
Largely yes, with one major exception. An 11-speed KMC chain works on Shimano, SRAM (non-Flat-Top), and Campagnolo 11-speed drivetrains. The exception: SRAM Flat-Top chains (used in SRAM AXS road and SRAM T-Type AXS MTB 12-speed systems) require the matching SRAM Flat-Top cassette and chainrings. A Flat-Top chain doesn’t work on a standard 12-speed drivetrain, and a standard 12-speed chain doesn’t work on a Flat-Top drivetrain. This is the most common 12-speed quote-stage error, and we name Flat-Top chain SKUs explicitly to avoid it.
What freehub bodies do your cassettes fit?
Shimano HG (the most common, covers Shimano cassettes through 11-speed), Shimano Microspline (12-speed Shimano MTB), SRAM XD (11-speed SRAM MTB and some 12-speed), SRAM XDR (12-speed SRAM AXS road and some MTB; XDR is XD with a wider freehub body), and Campagnolo. Each cassette SKU names the freehub body it fits explicitly.
What’s the wear cycle on a chain and cassette pair?
Chains typically reach replacement at 0.75% stretch, which corresponds to roughly 3,000–10,000 km depending on use, terrain, and rider weight. Cassettes typically last two to three chain replacement cycles if chains are replaced at proper wear intervals; if chains are run beyond wear and damage the cassette teeth, the cassette needs replacement with the chain. This is the consumable pair logic that justifies pair pricing.
What’s the difference between hollow-pin and solid-pin chains?
Hollow-pin chains have the chain pins drilled through, reducing weight by a small amount but adding a small price increase. Solid-pin chains are slightly heavier and slightly more durable in extended use. Higher-trim chains use hollow-pin construction; workshop-grade chains use solid-pin. The SKU spec sheet names which construction applies per chain.
Do you supply 12-speed Shimano chains and cassettes?
Yes. 12-speed Shimano covers Microspline-freehub MTB cassettes and the matching chains. Shimano 12-speed road (in the Shimano Di2 ecosystem) is outside scope per the drivetrain page note on electronic shifting.
Do you supply SRAM Flat-Top AXS chains and cassettes?
[SRAM Flat-Top AXS chains and cassettes are part of the closed AXS supply chain. We confirm Flat-Top supply per market in your quote because wholesale rights vary by region and distributor agreement; the Flat-Top variants are not available in every market we serve.]
What’s the warranty on wholesale chains and cassettes?
Manufacturing-defect coverage on both. Chains and cassettes are wear items; warranty doesn’t cover wear-related replacement, which is expected as part of the consumable use cycle. The honest answer: defect coverage yes, wear coverage no. Confirmed per SKU in your quote.
Can you supply standing-order arrangements on chain and cassette reorders?
Yes. Workshops with predictable reorder demand on specific ecosystem combinations (for example, quarterly reorder of 11-speed Shimano HG cassettes and matching chains) can set up standing-order arrangements at agreed intervals. Quote stage confirms the arrangement structure based on your reorder cadence and customer base.
Do you supply masterlinks separately for shops that lose them in service?
Yes. Replacement masterlinks across the chain ecosystems we supply are available as a separate consumable. A useful add-on for service-active workshops where masterlinks occasionally walk off during service.
Do you supply Campagnolo cassettes?
Yes, on a niche-supply basis at launch. Quote-stage confirmation depending on speed count and ratio requested. Campagnolo is a smaller portion of our supply chain at launch; we expand if demand develops in your market.
Do you supply track-specific chains and cogs (for velodrome track bikes)?
Not at launch. Track chains use distinct dimensional standards from road and MTB chains and have a closed supply chain at our launch volumes.
Do you supply single-speed and fixed-gear chains and cogs?
Not at launch. Single-speed and fixed-gear drivetrain components are outside our launch scope; a separate enthusiast category to develop later.
Can you supply a starter chain and cassette inventory for a new shop?
Yes. Quote stage confirms a starter inventory based on your target customer mix (road, MTB, gravel, mixed) and your service capability. 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 relationship between this page and your drivetrain page?
This page goes deeper on the chain-and-cassette pair logic, the wear cycle, the Flat-Top compatibility detail, and the pair pricing and standing-order arrangements that workshop reorder volumes warrant. The drivetrain page covers the broader drivetrain category including derailleurs, shifters, cranksets, chainrings, and bottom brackets, which are different commercial categories from chains and cassettes (they aren’t consumable pair items). Both pages share the same operational supply chain; the differentiation is in commercial framing and category-specific depth.
