Brake Levers - 04

BRAKE LEVERS:
MAFAC Professionnel 429 - racing type brake levers - traditional non-aero cable routing - post 1976 integrated cable adjusters having a "knurled gum hood" - pre 1980 standard aluminum alloy bodies - "full style" translucent gum hoods - factory "drilled" Clear anodized aluminum alloy levers / pre 1980 with 34 hole (17 holes per side) lever blades / pre 1980 "narrow" profile lever blades - patented stainless steel mounting clips / pre 1980 solid band marked "Breveté SDGD" - model Course 429 ... [The Professionnel Course 429 or "perforated racing lever" was introduced to market for model year 1975 as a complement as well as yet a further refinement to MAFAC’s long tenured Course 121 dural racing levers having instantly identifiable half hoods and their immediate successor the Course 128 or 2000 racing levers having Black colored full hoods and solid lever blades. In its first incarnation, the Professionnel Course 429 featured an integrated cable adjuster having a metal barrel with fluted top and rubber "O" ring, but this mechanism was replaced during 1977 by a similarly integrated cable adjuster having a "knurled gum hood". Additionally, while the "drillium" lever blades on the Course 429 may have offered a nicely variegated surface for better finger grip, the profile of the original blade was eventually determined to be a bit too narrow at its further points for those riders having larger hands, and therefore, it was widened toward the bottom end coincident to model year 1980 production (...this re-tooling also begot a change in the number of holes stamped into the lever blades themselves - reduced from 34 holes at 17 per side to 30 holes at 15 per side). It was also only after 1979 that the "extra légère" or "lightweight" edition of those Professionnel Course 429 brake levers having Black composite bodies were ever offered - all previous versions were built upon the same standard aluminum alloy bodies that continued to be made available alongside the plastic type from 1980 onward. The specifics of the MAFAC Course 429 brake levers mounted onto this bike are absolutely accurate with respect to what was actually fitted on Peugeot PY-10 CP models produced throughout 1978, although it would be appropriate to point out that other models of the PY-10 including select factory show bicycles featured the Course 529 brake lever, that being merely a Gold anodized version of the 429.]
