2006 Campagnolo ~

10 speed - Record, Chorus, and Centaur

In 2007 Campagnolo made two important changes that effect compatibility.

First, they moved from square tapered bottom brackets to external bottom brackets. Cranks made in 2006 or before will NOT fit the new external bottom brackets. To continue using older parts you will need to mesh pre '07 cranks and bottom brackets only to each other.

Second, Campagnolo moved to faster shifting left shift levers. These are designated on the left Ergo lever with a QS which stands for Quick Shift. The QS levers are only compatible with QS front derailleurs. If you are using Ergo levers made in 2006 or before then you must use the pre-QS Ergo levers and pre-QS front derailleurs together.

Hubsets were also changed for 2007. But, the older hubs are completely compatible with current cassettes and drivechains. See below for the older hub style that some riders still prefer.

We try to maintain a good stock of these pre-2007 parts so those that prefer to keep their older parts running can do so. See below.

Double Chainring Setups ~

2006 Square Tapered Bottom Brackets ~

The Chorus bottom bracket spindle is 102mm long (center) and fits either Record or Chorus square tapered cranks (all Campagnolo cranks made BEFORE 2007. The Record bottom bracket (on left) uses a carbon composite shell that drops 43 grams in weight. A Campagnolo or Shimano cassette tool is used to install or remove Record and Chorus bottom brackets.

The Centaur BB (right in pic) is 66 grams heavier than Chorus and uses a less reliable wrench system to install or remove. To save weight, the Centaur spindle is hollow; you can look right through it! As it is 111mm long, it can only be used with Centaur and Veloce cranks, not Record or Chorus.

2006 Square Tapered Aluminum Cranksets ~

The Chorus crank is cold forged of very clean and consistently grained light aluminum alloy and weighs just 647 grams yet it is extremely strong and dependable. The pedal hole is pierced during construction for much greater strength than drilling. The 5th spider arm is milled right out of the main crankarm for more strength and beauty. The Record crank is just like the Chorus except that it adds light alloy fixing bolts as well as a new surface treatment to the chainrings for even greater durability. The Centaur crank (on right) has all 5 spider arms visible.

	Chorus and Record require 102mm Chorus or Record bottom bracket
	Centaur crank requires 111mm Centaur or Veloce bottom bracket
	170, 172.5, and 175mm lengths

All Campagnolo cranks feature the latest "Ultra-Drive" chainrings with precisely machined teeth and shifting ramps for the fastest, smoothest shifting on the planet.

2006 Square Tapered Carbon Cranksets ~

Over 5 years in development and testing, the Campagnolo Carbon cranks are a masterpiece of modern cycling technology. Weighing nearly a pound less than the already very light Record AL crank, the Carbon crank is truly a stunning work of art as well as the finest performing crank on the market. These cranks use Multidirectional Carbon Fiber (MDCF), a new composite technology recently introduced in the aerospace industry. MDCF distributes the carbon fiber in all directions for greatly increased strength. For even greater security, Unidirectional Carbon Fiber (UDCF) has been judiciously positioned to further enhance the already outstanding mechanical performance of these beautiful cranks. Weight is just 500 grams.

	Record carbon crank = 500 grams
	Chorus carbon crank = 515 grams
	Centaur carbon crank = 583 grams
	Record aluminum crank = 632 grams
	Chorus aluminum crank = 647 grams
	Centaur aluminum crank = 660 grams

Apart from the label, the Record and Chorus crankarms are exactly the same. The only difference is in the chainrings. The Record rings have a new treatment that increases resistance to wear and tear. Centaur uses Chorus chainrings and the crankarms are the same except they fit only the 111 mm Centaur bottom bracket. Record and Chorus fit both Record and Chorus bottom brackets.

2006 Front Derailleurs ~

These front derailleurs work with all Campagnolo Pre-2007 shift levers - 9 and 10 speed. Combined with Campagnolo machined chainrings and proper adjustment, the Chorus front derailleur (on right) will provide nearly countless miles of fast, trouble free shifting. The Record model (on left) is 5 grams lighter as it uses an extra stiff and fast carbon fiber outer cage plate. Centaur, which uses less fancy finishing bolts, weighs 11 grams more than Chorus.

FIT: Brazed on front derailleurs are used when your frame has a corresponding hanger (pictured on right) permanently or attached to the frame. They are also used with the clamp-on BO adapters pictured below. If you require the front derailleur to clamp to your bike then carefully measure the outside diameter of your frame's seat tube at the level of your large chainring.

Tip: All Campy 10 speed front derailleurs work on 9 speed setups. Just unclip the plastic insert on the front of the outer cage plate to widen the cage.

Available for both regular (53 x 39) chainrings and compacts, select below !

2006 Hubs ~

The internationally patented Campagnolo hubs are an engineering marvel. Used in Record, Chorus, and Centaur groups, they are incredibly light and tremendously serviceable. Most importantly, because of their exclusive oversized shaping, they build stronger wheels than ever before. The shells and internals are the same in all three models. Centaur uses resin dust seals and plastic QR end caps. Chorus upgrades to machined end caps and dust seals. Record adds lubrication ports and titanium pawls. Extralight quick release skewer is included with each hub.

Select the hole drilling, 32 or 36h, to match your rim. Riders over 200 lbs or really rough riders should consider 36h. Most others do well on 32h.

Hubsets (front and rear together):

Pairs still available: silver Centaur in 32 hole!

Front hubs only:

Single fronts still available: silver Centaur and Chorus in 32 hole plus Record in 36 hole!
