CHIGASAKI STYLE**Faster in red!!
by: Naoki Sakai

For more speed and efficiency, changing component areas to Rotor ceramic bottom bracket, Oval shaped Rotor 110 50T, or TNI Big Pulley can be a major difference.  Here they are in bright red colors, to match or enhance your bicycle’s aesthetics, while functionally giving you greater power in your pedaling!! 

 

 

 

The Rotor Q Ring system is subtle, but efficient ovality to fine tune your pedal performance.   With Q Rings you can ride further and faster with less fatigue because you are using your muscles more efficiently.   The oval shape Q rings boost performance by varying drive train resistance during pedaling inline with the legs’ natural strengths.  By orienting the diameter of the oval to the weakest point of the pedal stroke and the widening diameter to the strongest point of the pedal stroke,you can take full advantage of the most productive part of your pedal rotation.  The Rotor Q Ring 110 50T red is priced at 18600 yen +TAX.

 

 

 

 

 

The Rotor BB Presse fit 4624 ceramic bottom bracket sells for 25200 yen+TAX.  It weighs a mere 125 g.  It is made for 46 mm diameter, 24 mm axle BB shell, designed to work with Rotor and Shimano 24 mm cranksets.   It is compatible with a wide range of bicycles. 

 

 

 

The TNI speed pulley ceramic bearing 12/16T big pulley is designed for Dura ace Shimano RD9100, rear derailleur use.  It weighs 80 grams. To gain greater efficiency, a big pulley is a nice addition.  It will require a chain extension, as the size of the pulleys are larger than regular dura ace pulleys.  The TNI Big Pulley sells for 17500 yen +TAX.
