Panasonic CB4000

This 1993 model of Panasonic’s CB4000 is a classic cross bike. It combines the rare Shimano 700CX group set with a double-butted chromoly frame made of Tange Infinity tubes.

The 700CX group‘s most noticeable feature is its unusually narrowly-geared cassette. You would rather expect that on a road bike. The cycling community never hold it in high regard, except for bike couriers and delivery riders who absolutely loved it for its smooth transitions. After a year, Shimano phased the group set out.
