In today’s Daily News Digest: Guardian column: ‘Why I don’t think Froome will win a fifth Tour de France’; Landa: ‘I sacrificed myself without any benefit to the team’ on Izoard stage; BMC Racing announces contract extensions for Bookwalter, De Marchi, Schar, Wyss; Business Insider: Brailsford explains why Froome is so good at winning Tour de France; Nibali set to return to racing at Tour de Pologne in preparation for Vuelta a España; Cycling Australia to allow disc brakes in road racing effective immediately, with exceptions; Quarq launches two new DZero-based power meters; Abbey Bike Tools releases precision Saddle Fit Kit System.
Quarq has added two new models to its growing DZero family of chainring spider-based power meters: the DZero DFour91, which is meant to combine seamlessly with Shimano’s latest Dura-Ace R9100 four-arm chainrings; and the DZero for Specialized to fit the latest S-Works carbon crankarms.
Quarq introduced its DZero family of power meters last year, based on a new modular crankarm-and-spider design that allows users to mix-and-match, or upgrade, as needed. All DZero power meters also gained updated circuitry for improved accuracy and battery life, Bluetooth and ANT+ wireless support, accelerometer-based cadence measurements, and an IPX7 waterproof rating for improved reliability when riding in wet weather.
