Crankset - 02

CRANKSET:
Stronglight 105 ter (modified) - 122 mm BCD - 40/50 Black anodized and factory "drilled" aluminum alloy chain rings / 50 tooth ring having a threaded chain "roll off" pin / post 1972 "rounded" tooth profile - 170 mm Clear anodized forged aluminum alloy arms / 14 mm x 1.25 mm French pedal threads re-cut to 9/16" x 20 TPI / pre 1982 23.35 mm x 1 mm cap threads - model 105 ter : Stronglight dust caps (omitted) - chrome plated steel - 5 mm Allen key release : Stronglight Super Competition chain ring bolts - aluminum alloy - 5 mm Allen key release - pre 1984 with "STRONGLIGHT" logo markings - model 61D (hex nut) / 62D (threaded sleeve) : stainless steel protective pedal washers ... [To my way of thinking, this variation of Stronglight is one of the most esthetically pleasing components ever to grace the bottom bracket spindle of a racing bicycle. It is also the very same basic crank (...excepting the Black anodized coloration in evidence on the chain rings) that Thevenet rode to victory in 1977 for his second career Tour de France win. Despite what the most fervent Campanista may wish to believe, even in an uncut, undrilled, and unaltered from stock form, the Stronglight 105 ter, 105 bis, and their predecessor the Super Competition 93, were absolutely the lightest crank sets, as well as some of the most durable, to be found in the pro peloton at that time - and I have opted to supplement that inherent "lightness of being" a bit further by virtue of fitting a set of first edition Stronglight Super Competition alloy chain ring bolts as introduced in late 1976. With respect to the 40 tooth chain ring seen here paired with a matching mere 50 tooth "big" ring, I have effectively opted for an "old school" version of what would now be known as a compact crank setup in keeping with my desire to reconstruct a distinctly purpose built, single day, non staged, short course style, vintage pocket racer. Having yet still a respectable top gear of 103.85 inches in consideration of that 13 tooth small cog on the Zeus freewheel, this particular setup thereafter provides a near perfectly stepped range of close ratio gearing that can be accessed in a "straight up / straight down" shift sequence (...assuming that one avoids the two cross chain combinations). I should also point out that I have chosen to fit aftermarket and non-standard stainless steel pedal washers in order to help protect the anodized finish on the crank arms. Regarding those Graftek G-1 examples sold new as a "complete" bike, they would have usually come fitted with a Campagnolo Record model 1049 crankset having 42/52 standard chain rings.]
