Campagnolo Chorus Ergo 12 Speed Groupset


12 speed. 8 pieces (Ergopower Ultra-Shift carbon levers with cables and housing, bottom bracket cups, Ultra-Torque Carbon crankset, Dual-Dual Pivot Skeleton brake calipers - front and rear, Chorus cassette, Chorus Ultra-link chain, front derailleur and rear derailleur).

Introduction of the Chorus 12 speed groupset is a further example of high-performance transmission specifically for an already large group of users wanting a top level yet versatile product. Those who appreciate Campagnolo top-of-the range functionality have always loved the Chorus model for its excellent price-performance ratio.

No compromises have been made in this extension of the characteristics and main advantages of Super Record and Record 12 speed groupsets to the new Chorus 12 speed. In addition to this, the Chorus model also comes with the brand new Ultra Torque 32/48 crankset, together with the new 34/50 and 36/52 chainring combinations. The combination with 11-29 / 11-32 / 11-34 dedicated cassettes makes Chorus the ideal groupset for those wanting a multi-purpose cycling experience.

    Here is what I would say:

    Posted by R. Randolph on 19th Nov 2021

    This 12-speed gruppo was purchased for my son who primarily rides a couple of charity rides per year. He has been riding my old 10-speed Campy Chorus gruppo for the past decade. Now that his wife has done a charity ride with him this fall, they both want to do more cycling. This set marks the third Campagnolo grupo I have purchased from Texas Cyclesport. That does not mean I go through gruppos like a competitor goes through water bottles on a mountain stage of the Tour de France. I have bought the three sets for three different family members. I keep coming back to Texas Cyclesport to make these purchases for two reasons: the service and the very competitive prices. On this order there were no longer any Chorus 12-speed cassettes available...anywhere. I confirmed this on-line later with other five suppliers in the US and two in the UK. Michael at Texas Cyclery called me within an hour after I placed my order to let me know of the Chorus unavailability and to offer me a Campy Super Record 12-speed cassette at a fair price so that the full order could be shipped at once. That is the kind of personal, responsive service I associate with Texas Cyclery. In addition, the price I paid for this gruppo was again the best to be found in the US. I am coming back to them this winter to order a new set of wheels for myself.

    Great upgrade from a Centaur 10-speed group.

    Posted by Keith Dunlop on 27th May 2020

    This is a fabulous upgrade from my old 10-speed Centaur group, and the deal. made choosing Chorus over Record a no brainer. The biggest difference is the feel of the new style shifters - shifting has a firmer feel to it and the braking leverage and power is noticeably better. The hood and lever shapes are also vastly improved and feel natural in the hand. Also, having less steps between cogs makes for smoother gear changes and I'm riding more in the middle range of the cassette by moving down from a 53/39 to a 52/36. The rear derailleur is more complex and takes longer to get dialed in, but once its adjusted properly shifting is quick and precise. Finally, I made the mistake of using a KMC X12 chain due to the installation ease. It worked, but was quite noisy. I swapped it out for the supplied Chorus chain and the drivetrain is now shifting smoother and is whisper quiet.

    In short, the best upgrade I've ever made to my Ridley Noah!

    Great Upgrade

    Posted by Ryan McCormick on 25th Aug 2019

    Bought this to replace a 20 year old Record 10 groupset. Couldn’t be happier. Liked that everything was a plug and play replacement. No other upgrades necessary. Quality is typical Campy. And oh man, components have come a long way in the past 20 years. Great price as well from TCS! And oh yea, super shipping.
