first_imgSure, we saw these back in August at Eurobike where they made a few other upgrades to their products, but they just sent over this glossy photo and some final specs. The set starts shipping December 1. Here’s the specs, full PR after the break:Technical Specifications PowerMeter:Crankset: Campagnolo Ultra Torque™ 11-speed crankset with CULT™ bearings and stainless steel axle,170mm – 175mmBottom Bracket: Campagnolo CULT™ bearing (included), bottom bracket cups not includedChainrings: Campagnolo Standard 53/39 11-Speed (135mm BCD)Weight: 779-786 grams (includes SRM PowerMeter, Campagnolo cranks, chainrings, and CULT™ bearings)Accuracy: ± 1.5% *Displayed power readingBattery Life: 1,400hTechnical Specifications PowerControl 7 Aluminum:Durable 6061 aluminum top case, gray anodizedLaser etched SRM logo130 hours ride time and memory (@1 second storage interval)Weight: 78g PRESS RELEASE: SRM Training System is proud to announce the launch of the Campagnolo PowerMeter complete with distinctive PowerControl 7 aluminum head unit. Uli Schoberer, owner and founder of SRM, collaborated with the Campagnolo design team and engineers to develop a unique PowerMeter and crankset combination capable of delivering accurate and precise data while maintaining the superiority and classic aesthetics of the Campagnolo brand.Campagnolo designed an Ultra Torque™ crank arm specifically for the SRM PowerMeter featuring an opening to access the retaining spring of the bottom bracket. The cranks will be available in 170mm, 172.5mm, and 175mm with a Q-Factor of 145.5mm. The Ultra Torque™ is Campagnolo’s offering in the integrated crankset sector presenting “lightness, rigidity, and efficiency of power transmission.” With technology containing CULT™ (Ceramic Ultimate Level Technology) the SRM Campagnolo Powermeter will demonstrate maximum smoothness and wear resistance. SRM Campagnolo PowerMeter users will also benefit from Campagnolo’s X.P.S.S™ shifting system (Extreme Performance Shifting System) guaranteeing superior speed and precision.The SRM Campagnolo PowerMeter has been race tested and approved by the Team Omega Pharma-Lotto. During the 2011 season the team trained and competed with the SRM Campagnolo Training System, contributing valuable data and feedback on the exclusive system. In addition, Philippe Gilbert and André Greipel won several races including stages of the 2011 Tour de France riding the SRM Campagnolo Training System.The design team at SRM combined rider feedback with research and testing, resulting in an enhanced accuracy of ±1.5%. An improved strain gage design, circuit components and manufacturing process are all important factors in SRM’s continuing innovation. As a testament to SRM and Campagnolo’s reliability, quality, and durability, a three year warranty will be included on cranks, bearings, PowerMeter, PowerControl, and batteries.The complete SRM Training System purchase includes the unique PowerControl 7 Aluminum (PC7) and all accessories (heart rate belt, speed sensor, multi-charger, download cable, handlebar mount, cadence magnet and SRM software). The PowerMeter Only option allows customers to purchase the SRM PowerMeter separately to be used with other ANT+Sport™ compatible devices or for a second bike with a shared wireless PowerControl. Availability:The SRM Campagnolo PowerMeter is now available to pre-order with shipping on December 1st.last_img read more

Keeping dairy cows outside is good for the outdoors

first_imgComputer simulation studies by scientists at the U.S. Department of Agriculture (USDA) suggests that a dairy cow living year-round in the great outdoors may leave a markedly smaller ecological hoofprint than its more sheltered sisters.Agricultural Research Service (ARS) agricultural engineer Al Rotz led a team that evaluated how different management systems on a typical 250-acre Pennsylvania dairy farm would affect the environment. ARS is USDA’s chief intramural scientific research agency, and this work supports the USDA commitment to promoting sustainable agriculture. Rotz works at the ARS Pasture Systems and Watershed Management Research Unit in University Park, Pennsylvania.advertisementadvertisement For this study, Rotz and his team used the Integrated Farm System Model, a computer program that simulates the major biological and physical processes and interactions of a crop, beef or dairy farm. The scientists collected a range of field data on grazing systems, manure management and their effects on nutrient loss to the environment. Then they used their farm model, supported by the field data, to evaluate the environmental dynamics of four different dairy farms in all types of weather over 25 years.The model generated estimates for ammonia emissions from manure, soil denitrification rates, nitrate leaching losses, soil erosion and phosphorus losses from field runoff. Estimates for emissions of carbon dioxide, methane, and nitrous oxide from both primary production and the secondary production of pesticides, fuels, electricity and other resources were also considered.Compared to high confinement systems, keeping dairy cows outdoors all year lowered levels of ammonia emission by about 30 percent. The model results also indicated that the total emissions for the greenhouse gases methane, nitrous oxide and carbon dioxide were eight percent lower in a year-round outdoor production system than in a high-production confinement system.Another plus: When fields formerly used for feed crops were converted to perennial grasslands for grazing, carbon sequestration levels climbed from zero to as high as 3,400 pounds per acre every year. The results also suggested that a well-managed dairy herd kept outdoors year-round left a carbon footprint 6 percent smaller than that of a high-production dairy herd kept in barns.These findings were published in Forage and Grazinglands in 2009.advertisementRead more about this work in the May/June 2011 issue of Agricultural Research magazine.
