Wilderness Systems Tarpon 140 Kayak with Rudder - Sit-On-Top

Wilderness Systems Tarpon 140 Kayak with Rudder - Sit-On-Top 11-speeds? Absolutely. - Lighter weight? You got it. - The marriage between a standard and compact crankset? Amen. - The Shimano Dura-Ace FC-9000 11-Speed Crankset has once again revolutionized the market through common sense design that for one reason or another no one else has attempted. - Finally we can run either compact or standard rings on one spider and even better FC-9000 hasn't compromised a thing. - In fact it's lighter just as stiff and sleeker than 7900. - Beauty and intelligence -- the total package. -Easily Dura-Ace 9000's most striking and recognizable feature is the FC-9000 crankset -- and this is for good reason. - On the surface the FC-9000 is a complete departure from the traditional aesthetics of Dura-Ace. - Gone are the days of the five-arm spider and the necessity for a separate compact crankset has also fallen by the wayside. - Instead 9000 features a shift to a new four-arm spider design. - This occured for many reasons but most notably it's because the four-arm spider matches rigidity with 7900 while shaving around 52 grams. - However 9000 has more than meets the eye. - Like 7900 you'll find the continuation of Shimano's Hollowtech II construction. - Over the past few iterations of Dura-Ace this manufacturing methodology has played an integral role in attaining weight reduction without sacrificing Dura-Ace's superior stiffness. -It's this balance of Shimano practicing tried-and-true forging methods while still treading into unknown waters that makes Dura-Ace more of a continuation than an innovation. - We mean this in the best possible way. - Shimano has learned what works and over the years has continually added to and improved the ideology of Dura-Ace. - Hollowtech II and Hollowglide are prime examples of this. - Strategic placement of hollow aluminum throughout the crankset and chainrings allows more structural material to be used and when coupled with Shimano's integrated bottom bracket creates an unrivaled weight-to-stiffness ratio. -The four-arm s. -. -. -Bike>Bike Parts>Cranksets/Chainrings>Road Bike Cranksets & Chainrings699. -99 More Details click ******************************************************
