Description
Tray Campagnolo super record 11v 39T
Road drivetrains campagnolo super record 11s 39t double inner chainring. The ultimate in performance and smoothness. The Super Record crankset is an astonishing concentrate of technology and performance: very high overall stiffness, extraordinary lightness, fast and precise shifting, the cult system and the titanium axle option further enhance the performance and uniqueness of this crankset.
Features & Benefits:
- Titanium axle and titanium fixing bolt left-hand thread reduces the weight of the whole crankset by 40 grams.
- Hollow cranks and chainring arms with ultra-hollow technology reduce the weight of the areas not exposed to stress, optimizing the weight/stiffness ratio of the crankset.
- Ultra-torque axle: it allows the power of the pedal stroke to be transmitted efficiently, without dispersing energy.
- New chainrings: the perfected mechanical machining in the areas responsible for the chain's ascent and descent guarantee maximum efficiency during shifting. Another evolution of the chainrings used by the pro-team in 2014.
- Different number of studs between the different chainring combinations: always optimal chain grip. Maximum shifting efficiency.
- Cult: the combination of the best ceramic balls on the market and special cronitect steel. The bearings are lubricated by means of oil increasing the crank's greasiness by 9 times. Corrosion resistant keeps the performance unaltered over time.
- Double center distance standard on all combinations: maximum rigidity and lightness thanks to the extension of the carbon fiber crank to the vicinity of the chainrings with center distance less than 112 mm and more than 145 mm.
Specifications:
- Length: 170, 172.5, 175 mm
- Combinations: 39/53 - 36/52 - 34/50 - weight: 603 gr.
Technologies:
- x.p.s.s. :x.p.s.s. Contains a project that was born with a specific aim: to give the new 11-speed groupsets campagnolo the best possible shifting. And the campy tech lab has done it again. The new design of the up and down chain zones has been studied in great detail using mathematical functions that simulate the possible movements of the chain on the sprockets and draw the ideal angles. In addition, numerous speed and shifting precision tests, carried out in the laboratory, have enabled the final optimisation. Even the profile of the sprocket teeth has been revised to make their action even more effective and to be in perfect synchronization with the 11-speed chain and with the derailleur, which has been intelligently designed to accompany the movement of the chain in an extremely fast and precise manner even during effort. In fact, the secret of this amazing result is the result of the perfect association and integration of all the components of the drivetrain, each of which is designed to work and function perfectly with the others: only in this way will you be able to enjoy the extraordinary performance that the new x.p.s.s. system will offer. cult - to understand what cult is and what performance advantages it offers for wheels and cranksets using this technology, there is only one solution: try it! It is possible to describe it, to evaluate its performance, to provide a technical definition, but it will never be possible to convey the real sensations and differences that you feel from the first pedal stroke on wheels and cranksets bearing the cult.... brand. But despite this campagnolo® would like to illustrate the exceptional results obtained by products equipped with cult technology in tests carried out by the engineers of the campy tech lab. Cult is the winning combination of the best ceramic balls on the market and cronitect® stainless steel bearings - the technological excellence of the German schaeffler group. Ceramic balls ensure minimal friction and long-lasting performance, while the thermochemically treated cronitect® bearings make the sliding surface of the bearings extremely hard and wear-resistant. But that's not all. Friction on the wheel and crankset is extremely low thanks to cult's lubrication system: all that is needed is a light film of oil instead of the usual grease. the results of the campy tech lab. 9 times smoother than standard solutions, almost no wear on the bearings and balls, coefficient of friction of the bearings and crankset.
