"Ultra·Drive™ chainrings - requires BB with L. 111 (for seat tube Ø 28,6 mm) or 115.5 mm (for oversize seat tube Ø 32 or 35mm.) The Centaur 10s crankset has the same technical innovations as the Record and Chorus groupsets in terms of the ultra-drive geometry of the chainrings. In the three sections of the chainring there are six pins and relative grooves that make it easier for the chain to move up onto the larger chainring. On the other hand, at two set points a special configuration of the chainring teeth makes it easier for the chain to drop down onto the smaller chainring. The 3X10 drivetrain is a racing drivetrain. Let’s debunk the myth that the triple crankset is an ‘uncool’ option that’s just for touring and not for racers. Just think of the Zoncolan climb in Italy or Angliru in Spain, where the pros have no hesitation in using it to get to the top faster and with less consumption of energy. Another misconception concerns the weight of the triple crankset. People make the exaggerated claim that it adds on kilos of weight, whereas in actual fact a triple crankset weighs just 100g more. That’s no much at all when you consider the vast range of gears it provides – 30 as opposed to the usual 20 – the much more efficient chain position, less attrition and the energy that you save. 3X10: 30 good reasons for climbing the toughest slopes with a smile on your lips."
