Campagnolo: 11 Speed Versus Triple Crankset

For its 2010 component range, Campagnolo presents a brand new 12-29 cassette for 11-speed drivetrains. The new cassette exceeds the commonly used 28 teeth of the sprockets offered by the competition and enables the 11-speed drivetrain to be even more versatile. In fact, the new 12-29 combination used with a compact 50-34 crankset generates metric developments analogous (2,49/8,84m) to those of a 53-42-30 triple crankset.

The use of a compact crankset instead of a triple also makes it possible to obtain better chain alignment and a substantial weight reduction. The really big news is that Campagnolo has managed to keep a single rear derailleur configuration, avoiding the problem of the double option: choosing a derailleur with medium or short arm.

As a result there is just one rear derailleur option, which works precisely and optimally from the 11-tooth cog to the 29-tooth, in combination with all available Campagnolo 11-speed cranksets. The 12-29 cassettes are already available for the Super Record, Record and Chorus.

According to Campagnolo the era of the triple is drawing to a close, thanks to the 11-speed technology in combination with the new 12-29 cog set. Some years ago, with the introduction of the compact crankset, the number of users of the triple fell considerably, marking a trend that has continued year by year. With Campagnolo’s introduction of the 11-speed group sets last season, the advantage given by the compact became even more pronounced.

The classic triple configuration (53-42-30) was often combined with a 13-29 sprocket set. When this configuration is compared with a compact 50-34 and Campagnolo’s the new 12-29 sprocket set, it is clear the new 29 tooth cog, paired with the 34 tooth chain ring of the compact, allows metric developments similar to those of a triple crankset with a rear 29 tooth cog. This difference is only 30 centimetre.

Even for the hardest ratios, the two configurations are very close in terms of metric development: the 53-13 of the triple compared to the 50-12 of the compact has a difference of only 20 cm. The lower weight, a reduction of the Q and U factors, less intersection and overlapping of gear ratios, and consequent better chain alignment are additional advantages with the compact set-up.

Campagnolo’s 2010 Shamal Ultra wheelset range feature improvements in terms of both weight and performance. Campagnolo’s philosophy is to provide a consistently state-of-the-art technology with maximum performance. The range contains three models, a 2-Way Fit, a clincher, and a tubular version. The Shamal Ultra 2-Way Fit technology makes it possible to use tubeless or standard tires on the same wheels, so that riders can take advantage of the best features of both solutions depending on the use.

As of 2010, the wheel set will be equipped with hubs with ceramic USB (Ultra Smooth Bearings). Aluminium nipples and aluminium spokes with variable cross-section make the wheel light and sturdy. The rims of the clincher version have been lightened, thanks to a new production procedure for the aluminium extrusions making it possible to eliminate all the excess material. The mechanical and resistance characteristics remain, but performance has been increased, thanks to the reduction of the peripheral mass.
