Campаgnolo Campagnolo Super Record 5-Bolt 52 Tooth 11-Speed Outer FC-SR152

The maximum that you could ask for in performance and smoothness. The Super Record™ crankset is an extraordinary concentration of technology and performance: extremely high overall stiffness, extraordinary lightness, fast and precise shifting, the CULT™ system and the option with titanium axle, all this enhances even more the performance and unique... moreness of this crankset.Features & Benefits:- TITANIUM AXLE AND REVERSE THREAD TITANIUM FIXING BOLT Reduces the overall weight of the crankset by 40 grams.- HOLLOW CRANKS AND SPIDER ARMS WITH ULTRA-HOLLOW™ TECHNOLOGYReduced weight of stress-free sections, improved crank set weight to stiffness ratio.- ULTRA-TORQUE™ AXLE: Pressure on the pedals is transmitted effciently without any power loss. - NEW CHAINRINGS: Sophisticated mechanical features on the parts that move the chain up and down guarantee maximum effciency during shifting. A further evolution of the chainrings used by Pro-Teams in 2014. - DIFFERENTIATED NUMBER OF PINS DEPENDING ON THE CHAINRING COMBINATION: Constantly optimum engagement of the chain. Maximum shifting effciency. - CULT™ TECHNOLOGY: The highest performing ceramic bearings combined with Cronitect steel make for a combination that is 9 times smoother, resistant to corrosion and extremely long lasting. - DOUBLE STANDARDIZED BOLT CIRCLE DIAMETER ON ALL COMBINATIONS: Maximum stiffness and lightness thanks to extension of the carbon fber crank close to the chainrings with 112 mm for the small bolt circle diameter and 145 mm for the large one.Specifications: - Lunghezza: 170, 172.5, 175 mm- Combinazioni: 39/53 - 34/50- Weight: 603 gr.Technology:- X.P.S.S.™ Extreme Performance Shifting System: X.P.S.S.™ incorporates a project with a specific goal: giving Campagnolos new 11-speed groupsets the best shifting performance possible. And the Campy Tech Lab™ has hit the mark once again. The new design of the chains up shifting and downshifting has been analysed to the smallest detail with mathematical functions to simulate possible movements of the chain on the chainrings and design optimal angles. Furthermore, repeated lab tests on the speed and precision of the shifting action have allowed us to complete the products optimization. We have also reviewed the profile of the chainring teeth to enhance efficiency and compatibility with the 11-Speed chain and the cleverly-shaped derailleur to contribute to making the movement of the chain extremely quick, even under load. Indeed the secret of this amazing result is a perfect combination and integration of all the drive trains components. Each one of them is designed to perfectly fit and work with the rest. This is the only way you will be able to enjoy the extraordinary performance of the new X.P.S.S.™ system.- Ultra - Torque™: LIGHTNESS, RIGIDITY, SIMPLIFIED ASSEMBLY AND MAINTENANCE:ULTRA-TORQUE™. THIS IS CAMPAGNOLOS ANSWER IN THE INTEGRATED CRANKSET SECTOR. SIX YEARS AFTER INTRODUCING THE ULTRA-TORQUE™ SYSTEM, IT IS STILL
