Campagnolo 2011/14 Record Ultra Torque 11 Speed Carbon Chainset
The 2011-2014 Record crankset has a new logo and Campagnolo's new XPSS chainrings
Users of the previous generation 11sp will have had no complaints with their shifting but the new XPSS (eXtreme Performance Shifting System) raises the bar for front shifting to a new level. A new teeth design plus the new 8 ascending and 2 descending zones of the chainring enable top-class performance allowing even faster and more precise shifts.
An additional benefit of the new chainring design is that the inner ring is threaded to accept the chainring bolts (instead of seperate chainring nuts) making for easier and safer chainring changes.
Full-carbon unidirectional-multidirectional crank arms.
Light alloy chainring bolts.
Light alloy chainrings with XPSS (eXtreme Performance Shifting System) and hard anodization treatment.
Requires ULTRA-TORQUE BB cups.
Weight - 639g.
LIGHTNESS, RIGIDITY, SIMPLIFIED ASSEMBLY AND MAINTENANCE: ULTRA-TORQUE™.
THIS IS CAMPAGNOLO'S ANSWER IN THE INTEGRATED CRANKSET SECTOR.
AFTER MORE THAN 10 YEARS SINCE ITS INTRODUCTION THE ULTRA-TORQUE™ SYSTEM, IT IS STILL CONSIDERED, THE BEST PERFORMING CRANK-SET SPINDLE IN TERMS OF STIFFNESS, LOW WEIGHT AND EFFICIENCY OF POWER TRANSMISSION.
Campagnolo found a way to permanently conjoin the semi-axles of the bottom bracket to the respective crankset arms. This redesign made it possible to considerably reduce the lateral dimensions at the axle level and prevent annoying contact with the ankles when turning the pedals.
Assembly is simplistic: one single oversize bolt is enough to integrate the two semi-axles. With regard to torque transmission efficiency, this system is equally as effective as a single piece axle.
Furthermore, despite the narrow side profile, we have been able to position the bearings outside the bottom bracket shell, resulting in greater axle rigidity from the increased axle diameter. This breakthrough was obtained by using an ingenious mechanical system derived from many years' motoring experience in the rotation axle and engine shaft coupling sector: the Hirth joint.
In short , this is a joint with self-centring and self-aligning frontal teeth located in the middle of the bottom-bracket
axle where the ends of the semi-axles, integrated with the crankset arms, come into contact.
