P15-9 "Deluxe / Deluxe Touring Paramount" (April 1970-1979) In 1970, Schwinn developed a 15-speed semi-touring version of the Paramount by fitting a Campagnolo Record triple crankset and Campagnolo Gran Turismo rear derailer to the existing P13-9 frameset.This new model was deemed the P15-9; designating the first time that a Paramount's model number reflected the bike's gearing.To recap, the P13-9 v2 differs from the P13-9 v1 by the following: P13-9 (v2) short-coupled frame (1976-1977) For a short period of time, both the P10-9 (see below) and the P13-9 were offered with short-wheelbase, curved seattube configurations.Catalogs reflect that this model was available from 1976 through 1977, though as the P10-9 is listed with the same option from 1975 through 1978, there is a good possibility the P13-9's run extended into these additional years.Despite the inclusion of the "Tourist" name in some Schwinn literature for both the P10-9 and P15-9, these models bear no relation to the original, upright-bar P11 Paramount Tourist.P10-9 short-coupled frame (1975-1978) For a short period of time, the P10-9 was offered in a short-wheelbase, curved seattube configuration. Thanks to the book "The Custom Bicycle," we know that Frank Brilando - vice-president in charge of Schwinn's engineering at the time - changed Paramount fork rakes in 1978.This also marked the second time a Paramount model number was assigned to match its gearing, making it easier to designate each model: The P10-9 and P15-9 (and the corresponding ladies' P60 and P65) - equipped with the traditional Paramount geometry - took care of the sport/touring market in 10 and 15-speed configurations.Granted, the P13-9 Road Racing Paramount still carried the oddball model number, but it had finally become a purpose-built racing bike at this point.

There is no difference between a P13-9 v1 frame and a P10-9 - they're supposed to be identical.Though the 2" rake of the P13-9 v1 (and P15-9) remained the same, the characteristically English bend blades were was substituted with a far more Italianesque, gradual bend: It is worth noting that the blades remained Reynolds 531; Reynolds offered many different fork blade options during this era.No official explanation exists for the change, though it can be hypothesized that the change was done to modify the handling characteristics for racing, as the P15-9 (and soon-to-be released P10-9) continued to use the English bend blades until 1977.Keeping in line with the updated all-racing theme, fender eyelets were permanently deleted from the P13-9 v2.One other significant modification to the P13-9 v2 did not take place until 1972: A change in fork blades.
