Just as with the Campagnolo 11-speed outer chainrings, you should upgrade to the Campagnolo 11-speed inner chainring when you make the shift to 11 (speed), or when you wear out the inner ring on your existing 11-speed crankset.

As with the outer rings, it is not a 10-speed ring re-labeled, 11-speed is it's own thing. The teeth are 0.4mm narrower. The beautiful finish is the result of a new anodization process that is much stronger and lasts four-times longer than the old finish.

These 11-speed rings will work with most current 10-speed Campagnolo cranks. The two exceptions are Centaur and Veloce cranks, where the spacing is different due to the fact that both cranks utilize narrower stamped chainrings. 11-speed rings are machined.

You might be tempted to stick with your current 10-speed rings to save a little cheddar. Campy can't guarantee that your shifting will work with the older 10-speed rings. The slight change in the width of teeth could result in chain-suck. And the law of chain-suck is it happens when you need it least.

The Campagnolo 11-speed inner chainring is available in two sizes: 39 teeth in 135mm bolt circle diameter (standard) and 34 teeth in 110bcd (compact).

Older Chain Ring Generation

  • Familiarity: I've put it through the wringer

Make sure you pay attention to the generation of chain ring you are replacing. The rings being sold here are the older Campagnolo p/n FC-SR-034. The more recent 11 speed SR (2011-2014) use FC-SR-134. The difference is that with the new ring, the chain ring bold screws directly into the inner ring. With the older ring, you need a two-part bolt.

Unanswered Question

Hello, I have recently acquired a set...


I have recently acquired a set Campagnolo Super Record 11 speed 52/36. I would like to know if it is possible to buy the Campagnolo 34 Inner Chainring to put it in the set that I have. I am planning long mountain rides and would prefer to be equiped with the 34 inner chainring.

Thank you in advance. Hope to hear from you soon.

I currently ride a 2013 Campy Super Record...

I currently ride a 2013 Campy Super Record 11 speed (11x25) cassette. Can I put on a (12x29) without having to put on a longer chain or adjust the derailleurs? What's the largest cassette I can put on without having to put on a longer chain or adjust the derailleurs?

Many thanks,

Hi Nardo

I too have the Campy Super Record and have just put a 11-29 cassette on and yes you will need a longer chain.

On the big chainring, the 27 and 29 cogs slam into the cage on the derailleur . You can get away with it if you can remember to go onto the smaller chainring when climbing steep and only engage 27 and 29 when it gets 15% to 30% grade.
