This Vivalo brand (Japan) is quite popular amongst the Keirin professional ranks. It typifies the type of bike that you will see at the pro tracks, nothing particularly flashy, but meets the standards and every bit a well made racing implement. It's the kind of tool a top racer can pull in two million dollars a year riding. Note the nice seat stay cap design.

Dennis Young Hotaka, Japan...and just home from my first day riding at my local freshly resurfaced track. A smooth track is wonderful!
