Panasonic CB 4000

Weighing in at slightly less than 12kg, this 1993 version of Panasonic’s CB 4000 series is probably the lightest bike on this page.

Made of Tange Infinity double-butted tubes, it features a Shimano 700CX groupset, a pretty rare hybrid series that was common in 1993 and 1994 alone. With its overly wide gear ratios, its cassette seems a bit out of place for a hybrid bike.
