This is UNUSUAL in that it is ALUMINUM and Cottered!!! (pins included, i pressed them out carefully) SPECIFICATIONS 165mm lengyh Center-Center 106mm BCD (Bolt Circle Diameter) derived from adjacent C-C blt measurement of about 92mm OPTIONALLY can include orig.
Japanese Cottered Pin Bottom BracketCall me! The Chain i removed has SOME wear, but not overly worn.
(around 0.5 mark) 165 mm Crank Length..... Is considered on the shorter side for adult bikes, Typically used for: Shorter road bikes, people w limited motion of hips/knees, and most all FIXED Gears(to avoid pedal ground strikes) If your range of motion Extremely limited, try "JR" crank length of 152 or 160 mm, suntour makes affordable versions of this which i sell sets of too (new)!!
COMPATIBILITY Will work for Many bikes of the 1960s-90s If you are NOT sure, do not get this! I took it off of what i estimate was a repainted Japanese Bike, probably a 1970s Panasonic or similar road bike The reason i took apart the otherwise decently put together bike was there was a very slight bend in Top tube near the head tube. Very typical head one damage which did not effect rest of bike, that and the fact that the wheels were 27" steel meant they could be used for one of my MANY road bikes which Like 27" wheels!!! As of Sept 20, 2024, i retain ALL the parts of the original bike!T H A N K S F O R R E A D I N G!
