An extremely high quality cold forged road double chainring crankset
made by Sugino. The Ritchey Logic uses a 110mm PCD so it can take
inner rings down to 34 teeth. This crankset is equipped with Ritchey
38T and 50T chainrings. 175mm arms. It came off a new Rans Vivo I
upgraded to wider range gearing and has never been used. It can be
upgraded to take a third "outer" ring, typically 60 or 62 teeth to
convert it into a triple crankset for small wheeled applications.
$100 plus shipping.
