Campagnolo 11 Speed Rear Derailleurs

Compatibility, Cage Lengths and Standards

Before you buy, you need to get three things straight: cage length, actuation type, and frame standard. On cage length, Campagnolo 11-speed rear derailleurs come in short and medium configurations. Short cage suits cassettes up to 29 teeth - fine for flat or rolling road riding where you're running something like an 11-29. Medium cage opens things up to 32 teeth, which gives you more range for longer climbs or heavier riders who want a bailout gear. Running a medium cage when you only need a short one won't cause problems, but the extra weight and chain wrap aren't doing you any favours either.

HO geometry is worth understanding properly. These variants - denoted by 'HO' in the model name - are built around the chainline produced by disc brake frames with 142mm thru-axle rear ends. The geometry of the parallelogram is subtly different from a standard rim-brake mech, and fitting a non-HO derailleur to a disc frame (or vice versa) can leave you with shifting that never quite cleans up, no matter how many times you index it. Check your frame spec before you order.

On actuation, mechanical and EPS components are completely separate systems - more on that in the FAQ below. The short version: don't mix them. If you're unsure whether your current setup is worth upgrading or just needs new consumables, visit our Campagnolo 11 speed cassettes page or pick up a fresh Campagnolo 11 speed chain before assuming the mech is the problem. If you only need worn pulleys or specific hardware replaced, our jockey wheels and derailleur spares pages are the better starting point - a full mech replacement isn't always necessary.

How the Range Stacks Up: From Super Record to Centaur

Campagnolo's 11-speed rear mech lineup follows a clear hierarchy, and the differences between tiers are more tangible than the spec sheets suggest.

• Super Record: Titanium hardware, ceramic jockey wheel bearings, maximum carbon construction throughout. The cage is stiff in a way you can actually feel under hard out-of-the-saddle efforts, and the weight saving over Chorus is meaningful at around 60 - 70g depending on cage length. Ultra-Shift parallelogram geometry gives you shifting rigidity that holds up even when the drivetrain is under load. This is the mech for riders who've already sorted everything else and want the best available.
• Record: Carbon cage with steel hardware rather than titanium. Shifting feel is extremely close to Super Record in normal use - the difference becomes apparent at the limits, under sustained load or after a long winter of miles. A logical choice if you want the carbon cage without paying the full Super Record premium.
• Chorus: Where the range starts to make real sense for most riders. The Campagnolo Chorus 11s rear mech uses a mixed alloy and carbon construction that adds some weight but brings the price down considerably. Shifting quality is still excellent - distinctly Campagnolo in character - and the durability of the alloy body parts actually holds up well against UK road grit. Plenty of club riders run Chorus year-round and don't feel they're missing anything.
• Centaur and Potenza: All-alloy construction, heavier but robust. These are sensible choices for winter training bikes or riders coming into the Campagnolo ecosystem without wanting to spend Record money. Shifting is accurate if not quite as crisp under load as the carbon-cage options above.

It's worth pairing your new mech with a matched Campagnolo 11 speed front derailleur if you're replacing components - cross-tier mixing within Campagnolo's mechanical range generally works, but staying within the same groupset generation avoids any pull ratio inconsistencies. If you're curious how Campagnolo positions against the competition, Shimano 11 speed rear derailleurs and SRAM 11 speed rear derailleurs are both worth a look - they use different pull ratios and aren't cross-compatible, but understanding the alternatives helps you make the right call.

Keeping Your Mech Running Through a UK Winter

Road salt is the enemy. From November through to March, the grit and brine that coats UK roads works its way into every pivot point on a parallelogram derailleur, and Campagnolo's tight tolerances mean any stiffness in those pivots shows up quickly as sluggish or imprecise shifting. The best Campagnolo 11 speed medium cage derailleur in the world won't shift well if the spring pivot is gummed up with saline mud.

Clean the mech properly after every wet or salty ride - not just a hose-down, but actual attention to the pivot bolts with a dry rag and a drop of quality lubricant. The jockey wheel bearings on alloy-bodied mechs like Chorus and Centaur are more replaceable when they wear, which is worth keeping in mind. On Super Record and Record, the ceramic bearings are more durable but still benefit from a wipe-down. Don't ignore them until the wheels start grinding.

Derailleur hanger alignment deserves more attention than it usually gets. A bent hanger - often from nothing more dramatic than leaning the bike against a wall at the wrong angle - throws the whole indexing out and makes shifting feel vague across the cassette. Check it every few months with an alignment tool, or ask your local mechanic to do it during a service. It costs almost nothing and fixes 'mysterious' shifting problems more often than any cable tweak.

On cables: sealed, high-quality gear cable housing makes a genuine difference to mechanical shifting through winter. Cheap housing lets moisture in, the cable corrodes, friction increases, and the crisp action you paid for disappears. Fit good housing, cap the ends properly, and replace the inner cable at least once a season if you're riding in all weathers.
