Wilderness Systems Northstar Tandem Kayak with Rudder - 2013 Model
Rotor made its mark on the cycling world largely through the effectiveness and popularity of its Q-Rings but it still recognizes that there are those who prefer to stick with round chainrings. - That's why the Rotor 3D Plus Compact BBright Crankset accomplishes just that and it's setup to perfectly complement a Cervelo R5ca frame while still being entirely compatible with any BB30 bottom bracket frame. - Rotor first explored the use of alloy 30mm bottom bracket spindles through its involvement with the Cervelo Test Team. - And while the Trinity drilled arms and compatibility with round or Q-Rings remains the same these Rotor 3D Plus road cranks have a few small differences in comparison to the Rotor 3D Road Cranks. - The rigidity light weight and overall strength remain unchanged. - The 3D Plus Road crankarms are all of that due to Rotor's proprietary Trinity Drilling System. - On this crank Rotor drills all three parallel bores from the spindle end. - This is contrary to the 3D road cranks' drilling where Rotor alternates the direction of the bores from both ends of the crankarms. - Through this same-end drilling process Rotor was able to relieve the 3D Plus crankarms of even more excess material and therefore excess weight. - And just as importantly this was achieved maintaining both the rigidity and the strength-to-weight ratio that you need for race day. - On top of this the CNC machine work and laser etched graphics give Rotor cranks a distinctly industrial appearance. - The 30mm alloy spindle is sized to work with either BB Right or BB30 standards. - Rotor includes the appropriate fittings for both systems. - In fact with the proper Rotor bearing cups (BB30-BSA) the 3D Plus is able to be used in a standard 68mm English-threaded or Italian-threaded bottom bracket shell. - In any application Rotor's clever design and machine work is evidenced by its use of a locking preload collar that makes bearing adjustment a breeze once the crankarms are installed and torqued to . -. -. -Bike>Bike Parts>Cranksets/Chainrings>Road Bike Cranksets & Chainrings849. -95
