Campagnolo 13 Speed Chains
Campagnolo 13 speed chains are the one component you really can't compromise on if you're running an Ekar gravel drivetrain. At just 4.9mm wide, they're narrower than anything that came before them in Campagnolo's road or gravel range - a tight tolerance that's essential for clean, precise shifting across the Ekar's 13-speed cassette. Get the wrong chain, and the whole system falls apart. Literally.
Every Campagnolo 13-speed chain ships with a Ni-PTFE anti-friction treatment baked into the outer plates and rollers, cutting down drivetrain friction from the first pedal stroke. The factory lubrication goes deeper than a standard wax or oil application - Campagnolo uses an ultrasound bath process that forces lubricant into the inner link and roller contact points before the chain ever reaches you. That matters on UK gravel, where wet grit off a bridleway in November turns an under-lubed chain into a grinding paste situation fast.
The C60 steel alloy construction keeps tensile strength high despite the narrow profile, and the proprietary C-Link joining system makes installation clean and straightforward. If you're comparing UK prices on a replacement chain for your Ekar setup, you're in the right place.

Compatibility and Joining: What Fits a 13-Speed Campagnolo System
The 4.9mm chain width is not a marketing figure - it's the strict physical standard that makes Campagnolo's 13-speed ecosystem work. That narrow profile is specifically matched to the tighter cog spacing on the Ekar cassette, and there's no wiggle room. A Campagnolo 12-speed chain is measurably wider and will not seat correctly between the cogs. You'll get rubbing, muffled shifts, and if you ignore it long enough, real damage to the cassette body. It's not a bodge that works - it's one that doesn't.
The same goes in the other direction. Don't assume a narrow 13-speed chain from another brand drops straight in. The Ekar drivetrain is built around Campagnolo's own tolerances, and mixing in third-party chains can introduce inconsistent shifting feel and accelerated wear. Stick with the genuine article for a system this precise.
Joining the chain is done via the C-Link - Campagnolo's proprietary quick link - which clicks together securely under pedalling load and can be opened again with your fingers or a set of link pliers if you need to remove the chain for a deep clean. One thing to sort first, though: you'll still need to cut the chain to the right length using a quality chain breaker tool before fitting the C-Link. Get that sizing wrong and no quick link will save you. Need replacement joining hardware? Head over to our Campagnolo tools page to find the right chain breaker and C-Link for your setup.
What You're Actually Getting: Ekar Chain Construction
Unlike Campagnolo's road groupsets - where you're choosing between Chorus, Record, and Super Record tiers - the 13-speed gravel drivetrain currently operates as a single-tier system. There's one Ekar chain specification, and it's engineered to a high standard throughout. That's actually a straightforward decision: no guessing whether to spend up for a better chain variant, because there isn't one.
The chain is built from C60 steel alloy, which gives it the tensile strength to handle the load of off-road riding without the weight penalty you'd expect from heavier-duty construction. The Ni-PTFE treatment - nickel and polytetrafluoroethylene, the same low-friction compound used in high-end bearings - coats the chain's contact surfaces, reducing the friction between inner link, outer plate, and roller during every gear change. The result is a chain that shifts quietly and consistently, especially when new.
The ultrasound bath lubrication process sets the Ekar chain apart from a standard factory-prepped chain. Conventional chains are sprayed or dipped; the ultrasound method uses high-frequency vibration to drive lubricant into the microscopic gaps between pin and roller. It's why the chain feels silky straight out of the box, and why you get genuine longevity from that factory lube before you need to think about your own re-application routine. Pair that with a set of Campagnolo 13-speed cassettes and the system is optimised end-to-end.
Keeping It Running: Chain Care on UK Gravel
UK gravel riding is hard on chains. The Peak District in October, the chalk-and-flint bridleways of the South Downs, the red-clay lanes of Devon after a wet week - all of it introduces abrasive material that works into the narrow gaps of a 4.9mm chain far quicker than it would on a wider 11-speed setup. Grit doesn't care how good your Ni-PTFE coating is once it's packed into the rollers.
The practical upshot: don't strip the factory lube off too quickly. First clean should be a gentle wipe-down rather than a full degreaser bath. The ultrasound lubrication sits deeper than a surface treatment, and you want it working for as long as possible before you introduce your own chain lube into the equation. When you do re-lube, a wax-based product suits dry conditions; a wet lube makes sense for winter rides but attracts more grit, so wipe the excess off before you roll out.
On wear checking - and this is where people cost themselves money - a 13-speed chain should be replaced at 0.5% stretch, not the 0.75% figure you might use on an older 10 or 11-speed setup. The tighter cog spacing on the Ekar cassette means a worn chain damages the cassette teeth faster. A good digital chain checker takes the guesswork out of it completely. Replace the chain at 0.5% consistently and your cassette will last two or three chain cycles. Let it go to 0.75%, and you're likely replacing both at once. That's the kind of thing worth knowing before you're standing in the car park wondering why the new chain skips.
For checking and installation, having the right tools to hand makes the job clean and quick. Campagnolo's own workshop tools are worth considering if you're doing regular drivetrain maintenance - you can browse the range on our Campagnolo tools page.
Campagnolo 13 Speed Chains FAQs
How long does a Campagnolo 13-speed chain last?
In typical UK gravel conditions, expect somewhere between 1,500 and 2,500 miles depending on how much wet and grit you're riding through and how regularly you clean and re-lube. Check wear with a chain checker and replace at 0.5% stretch - not 0.75% - to avoid chewing through an expensive 13-speed cassette at the same time.
Can I use a 12-speed chain on a 13-speed Campagnolo drivetrain?
No. A 12-speed chain is too wide for the Ekar cassette's tighter cog spacing. You'll get rubbing between the cogs, poor shifting, and if you leave it, real damage to the cassette. The 4.9mm width of the 13-speed chain is a hard requirement, not a preference.
How do you join a Campagnolo 13-speed chain?
Campagnolo 13-speed chains use the C-Link quick link system - it clicks together under load and can be released by hand or with link pliers for cleaning. Before fitting the C-Link, you'll need to size the chain correctly using a chain breaker tool. Get the length right first, then close the C-Link.
