By introducing a new line of 12-speed transmissions, groupset specialist Campagnolo notes that it is adding ‘movement to frames in a way never before experienced’. The arrival of the Movement 12 versions of Super Record and Record, in both rim and disc brake versions, is seen to mark another milestone in the evolution of the drivetrain.
According to Campagnolo, ‘the new transmissions, available in both rim and disc versions, usher in a new era of performance, comfort, and reliability through a cornucopia of new technologies and solutions.’
The rim brake ergopower shifter offers several positions in order to better accommodate differing hand sizes and preferences, while the disc brake version incorporates the company’s AMS and adjustable reach system, which allows for not only personalized ergonomy but also custom performance.
The Ultra-Shift internals, which allow for multiple shifts of up to 5 gears downshifting or 3 gears upshifting in one single movement, have been completely redesigned to interface with the all-new rear derailleur. Also, thanks to a ‘substantial research and development project held by the Campy Tech Lab the new transmission offers some of the smoothest and most effortless shifting we have ever introduced.’
The company adds that ‘new cables and cable housing reduce friction to the lowest levels ever and maintain that silky smooth shifting for longer than the competition.’
Often considered the centrepiece of the transmission, the newest version of the rear derailleur incorporates a ‘plethora of next-level tech such as a new trajectory curve optimized around 11-29 and 11-32 cassettes’. It also introduces the evolution of Embrace Technology (first seen on the Campagnolo Rev11+ groupsets).
The next progression goes by the name of 3D Embrace technology, which not only keeps the rear derailleur vertically oriented in position for each sprocket, but it also now orients the unit along the fore and aft axis relative to each gear. Thanks to the aforementioned new tech and larger 12 tooth pulley wheels, one rear derailleur fits all and ‘guarantees optimum distance and engagement for each sprocket no matter what cassette option is chosen on the given day.’
Campagnolo adds that, with 12 gears, the need for a wide range of cassettes is effectively eliminated as the extra gear allows for single tooth increments all the way to the 8th sprocket. Riders can choose between 11-29 and 11-32 gear ratios with ‘zero compromise in gearing’. The new cassettes are compatible with current freehub bodies and rear spacing remains unchanged, allowing the rider to continue with his or her same wheels and frame.
Incorporating an additional gear into the same space did present the Campy Tech Lab with a challenge. An additional gear added, without widening rear spacing, meant that slimmer cogs and a completely new, thinner chain would be necessary, a particularly difficult challenge when considering Campagnolo’s commitment to maintain or improve durability and functionality. Although, Campagnolo points out that the new 12-speed chain, ‘while thinner and lighter also engages quicker and maintains the exact same durability of its 11-speed predecessor.’
