Bridgestone XO-5

The Bridgestone XO-5 was the most hybrid-like model of the XO series that Bridgestone Cycle sold in the United States, a line Sheldon Brown's archive describes as fast, sporty urban street machines meant primarily for pavement but more rugged than traditional road bikes. Where the top XO-1 used 559 mm (26 inch) wheels and road-type controls, the archive says the XO-5 was more like a typical hybrid with 622 mm (700c) wheels and a variant moustache handlebar of 22.2 mm diameter that used mountain bike type controls, and it judges the model rather too compromised, because that handlebar had fairly poor ergonomics with the supplied controls. A retro bicycle blog says the XO range ran from the XO-1 through the XO-5 in 1993, and Bike Insights lists the XO-5 from the 1994 Bridgestone catalogue as a flat-bar rigid bicycle in five sizes.
