The only thing keeping that podium girl’s kiss away is your ability, not the Super Record Ultra Torque Crankset.
The Campagnolo Super Record 11 crankset is the second-generation version of the Ultra Torque design. The basic structure of the crankset has gone unchanged. The heart of the system is still the "Hirth" semi-axle construction. Each crankarm has a hollow, steel semi-axle integrated into it. Each semi-axle has a bottom bracket bearing press-fit to the crankarm. And the opposite end of each semi-axle is serrated to mate to the other semi-axle at the middle of the BB shell in a massive-yet-precise connection.
The benefits of Ultra Torque are many: It provides you with tremendous drivetrain stiffness; it's inherently low-drag; and assembly is a breeze. Once you install your BB cups, the two crankarms come together through a simple 10mm bolt recessed at the meeting point of the two hollow semi-axles. Provided you torque the bolt down to the requisite 42Nm, you should never have a maintenance related worry.
…the benefits of Ultra Torque are many: It provides you with tremendous drivetrain stiffness; it's inherently low-drag; and assembly is a breeze… With Super Record 11, Campagnolo takes two big steps forward with Ultra Torque. The biggest buzz has come from their use of Ceramic Ultimate Level Technology (CULT) 5/32" bottom bracket bearings. (Keep in mind, with Ultra Torque cranksets, the bearings are pre-pressed onto the crankset semi-axles. They don't come with the BB cups.) These CULT bearings are unlike other ceramic bearings that require 'Private Reserve' grease formulations for lubrication. Instead, CULT bearings use oil, which minimizes drag, and it has the additional upside of making maintenance far easier. And Campagnolo goes further with drag-reduction by housing these bearings in a low-friction technopolymer cage, then pairing them to super-hard Cronitect races. Not only are these bearings remarkable for their low friction, but they're 200 times more resistant to corrosion than stainless steel bearings.
The other evolutionary change with the Super Record 11 crankset is in the Ultra Shift chainring design. The chainrings have been re-designed to work with the Super Record Ergopower levers to give you Campagnolo's fastest-ever front shifting. The outer chainring has 8 pins and specific "shifting sectors" and the inner chainring has unique teeth asymmetry to move the chain from one ring to the other in double-time. And while the rings are designed with different teeth profiles, they're synchronized to deliver wicked-fast shifts. A bonus with these rings is that they're Campagnolo's lightest-ever, and that they get a brand new hard-anodizing treatment to give them greater resistance to wear and corrosion.
The Super Record 11 crankset is built with Campagnolo's Ultra Hollow manufacturing technique. Its carbon fiber arms are molded to create a hollow structure. The chainring spider is also hollow. Unlike other carbon cranksets, there's no aluminum exoskeleton under there. The only metal is at the threaded pedal interface. And the steel semi-axles are molded directly into the carbon crankarms without the use of an insert. The Ultra Hollow design, when combined with the lightweight alloy chainring hardware, nets a crankset weight of 648g.
The Campagnolo Super Record 11 crankset comes in two chainring options: 53/39 and 50/34. It comes in 170mm, 172.5mm, and 175mm crankarm lengths, plus a 180mm option in 53/39 only. Bottom bracket cups must be purchased separately.
The actual weights of the Campagnolo Super Record 11 Ultra Torque Crankset: 170mm 34/50 is 635g. 170mm 39/53 is 643g. 172.5mm 34/50 is 644g. 172.5mm 39/53 is 648g. 175mm 34/50 is 646g. 175mm 39/53 is 652g. 180mm 39/53 is 670g.
