Ridley Asteria - 2012 White S

Ridley Asteria - 2012 White S The SRAM S975 BB30 Wireless Powermeter is SRM's most sophisticated SRAM Powermeter system to date. - The S975 features SRAM's integrated unidirectional-carbon crankarms and RED PG chainrings. - For a rigid attachment the S975 uses a CNC-machined aluminum spider. - The result is the holy grail of Powermeters--a race day crankset that feels looks and acts like SRAM. - You also maintain the hallmark weight savings of SRAM with the complete Powermeter system weighing in around an ultra-light 804grams without the bottom bracket. - The S975 Powermeter is extremely accurate operating on the powerful ANT+ wireless system with an expressed accuracy of +/- 2%. - The Powermeter is beast-approved as well with a cadence range of 30-255 rpm and a wattage range from 0-4096 watts it can handle any output--human or otherwise. - This is achieved through the use of eight strain gauges. - These are a system of sensors that detect any resistance and vary their output when experiencing applied force. - The next step is for the strain gauges to convert this data into electrical resistance so it can be measured. - The refinements to the system offer the stellar results that have already made the S975 Powermeter a hit with the pros. -Choosing the SRAM S975 BB30 Powermeter provides you with several advantages over other systems. - The weight savings and rigidity advantages of BB30 are obvious but our favorite gain by far is that the S975 system is compatible with other 10- and 11-speed groupsets. - Additionally you can swap out the RED chainrings for Shimano Rotor SRAM and FSA Pro/Super Road chainrings. - The SRM S975 Powermeter features a predicted 1400 hours of ride time per battery compared to the 400 hours of battery life of Quarq's S975 system. - This means more time in the saddle and less time worrying about your battery. -The SRAM S975 Powermeter is compatible with various training software such as Training Peaks SRM and Strava. - The S975 operates wirelessly with ANT+ Sport and can be used seamlessly. -Bike>Bike Parts>Cranksets/Chainrings>Road Bike Cranksets & Chainrings2744. -95 More Details click ******************************************************
