<------------------- SOLD -----------------> Stronglight 105 bis crankset - 42/52 double - 122 mm BCD (NOS / USED)
Stronglight 105 Bis crankset - 122 mm BCD - 42/52 Clear anodized and factory "drilled" aluminum alloy chain rings / 52 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 (...which require a specialized puller - do NOT try to use a common French T.A. puller as you will likely strip the threads out of your Stronglight crank arms) / pre 1980 stylized "STRONGLIGHT" logo cast into the outer fluting of each arm / pre 1979 absent fluting on the backside of each arm / pre 1979 having crank arm length and pedal thread type stamped into backside of each arm - model 105 Bis : Stronglight chain ring bolts - chrome plated steel - 5 mm Allen key release - model 61 (hex nut) / 62 (threaded sleeve) ... [NOS chain rings and chain ring bolts paired with USED crank arms that were removed from a show bike that never garnered much in the way of actual road use - while the NOS bits are in perfect condition, the crank arms themselves exhibit only light evidence of use, primarily in the form of "halo" markings around the pedal holes and at points along the very bottom of the arms themselves - 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 crank setup 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, both the Stronglight 105 Bis and its 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 - a superb example of high end French racing kit from the late 1970’s through early 1980’s]
