    non-cottered steel cranks

    I don't recall ever having a non-cottered steel crank but for whatever reason, I find them appealing. What other vintage 'performance geared' would one recommend?

    I forgot about the Gnutti and spline. Curious how well they kept them tight vs. a square w/taper.

    juvela- Appreciate the links. Just in the research mode as an upgrade for my clunker. Not concerned that much of weight but a slender arm, delicate looking spider and over 170mm.

    alas, all but the NERVAR Sport would be quite dear if findable. the NERVAR came stock on the Raleigh Super Course MK II in the mid-'70s and on one model of Motobecane around the same time. there was a model of Bianchi which fitted it ~1973. it employs the same chainwheels as the NERVAR Star five-arm model.

    You can also find steel non-cottered cranks on some cheap kids bikes; a neighborhood kid had one.

    I had one on a MTB parts bike. No way it was going to come off that spindle.
    I have spoken.

    Odd that the crankset pictured isn't steel and isn't 86bcd like the text reads.

    And speaking of Stronglight cranks, I went to a swap today and found a 40t ring for my SC57 crankset for $10.

    I've got a very early '60's PX10, in need of extensive restoration, that has Stronglight SC57 cranks on it. One of the green ones with orange-painted lugs, but the paint is really beat from exposure.

    I got another pair of SC57 cranks (BSA-threaded) from a basket-case Italian bike that must have been taken apart not long after it was new. The rear "no Record" hubshell was bent, but the rest of the parts that were put in this huge box were in excellent shape, including a Brooks Pro, a Gran Sport mech with cable adjuster barrel, and a 2nd-gen Record front mech. Also it had Mafac brakes, but the frameset had been left to rust and I was never able to identify it before I gave it away to a guy who had it powder-coated blue. The cranks were mounted on a Magistroni bb.

    I've also had a couple of 1st-year Record cranksets come my way, one in exchange for work and the other attached to a 1959 Paramount. I sometimes wonder what these things are worth.

    True first generation Campagnolo Record cranks are very dear and go for serious money. They are best identified by the machining of the spider to crank arm interface, the region that later became a stress riser and shows small cracks from time to time was cut away. That and examples that retained the pedal shields over time, often removed to fit pedals with the longer threaded region.

    hello dddd -

    thanks very much for your complete answer. how were you able to determine that your px is a ten? i would have thought that an early sixties example would be an eight or a nine. is there a peugeot timeline posted somewhere? (not questioning your statement) have seen one or two examples with that green/orange livery. wonder if it predates or is contemporaneous with the royal blue/yellow one...

    the italian bike must have been a one down from the top model. a number of italian mfrs put a record chainset on the top model and a verot on the next one down during the sixties.

    yes, those early record chainsets must be worth a small fortune, especially on honshu. have had one or two come through over the years. recall the dustcap at the inner end of the pedal hole and the lack of webbing between the two lower spider arms and the crank arm itself.

    thanks as always for your explanations

    BCA from PA or NJ, used to sell bikes with cotterless steel cranks. I do not have a clue who made them.

    I assumed the Peugeot was a PX10 simply because of the front/rear chroming, and the usual other components, but the rear derailer on this one is the Export61 Luxe, with chromed finish and thumbwheel limit adjusters.

    Both of my early Record cranksets have the chromed pedal hole caps and machined (to remove webbing) right arm. I notice that Stronglight cranks are all machined this way.

    BTW, at the Swap meet on Saturday, I picked up a different pair of Simplex derailers from this approximate period.
    All-steel, with beveled alloy washer surrounding the flat-head screw at each spring pivot. My previous Export61 rear derailer finds had plastic covers over each pivot, but here these are fine-looking screw and alloy washer. This one isn't chromed however, but has the offset plastic pullies w/o ball bearings. A matching alloy pushrod front mech was included, for $50.

    We had a great day here, with local shop offering 20 and 40-mile morning rides, then free tacos and good beer, followed by the Tour of California riders coming past the shop across a mid-stage sprint line!
    Will be taking the day off tomorrow to ride down to the Stage 2, Individual Time Trial, where one of our club members has devised a route to allow us to view the race from several vantage points.

    hello dddd,

    thank you for all this information.

    wrt to px_

    checked at cr and the earliest one they show is identified as 1962 and a ten; so it sounds like you are spot on. they also have a gallery of a 1966 which shows the white delrin shift levers you fitted to your clubman.

    wrt amgen -

    they get into my area on sunday. will be fun.

    wrt juy gears -

    thank you for the photo. do you envision a project you will be using these on? or are they something to put in a "hope chest?"

    free beer and food at a bicycle swap meet! I have been to a number of them and have never encountered such a thing. folk in the sacto valley know how to do things right.

    It's sometimes hard to find a catalog for the exact year of bike, even a popular bike like a PX10.

    I was thinking of using these all-metal Simplex mech's on my Clubman, to replace the ageing, cracking plastic derailers.
    First I will have to install a later, non-offset cage, so I can re-fit my ball-bearing pulleys.
    Or I may just use a better pair of plastic Simplex mech's.

    The bike ride, free tacos and beer was all at Victory Velo, here in Auburn, ...they came through, then the T of C came through!
    The bike swap was actually down in Sac'to, the day before, courtesy of The Edible Pedal.
    And I bought the Simplex derailers from the proprietor of The Edible Pedal.

    Have fun with the T of C passing through! I missed today's time trial because my contractor friend suddenly became available to put up the scaffolding I need to repair my back deck.

    For the bottom line of cranks, I find these Shimano steel/aluminum interesting. Amazing when one thinks about it. The steel stampings and ramps, the perfect cut notches and then how they fasten it all together. Considered low end of course but the assembly weight isn't too far from full alloy triples.


    This was on a 1993 Schwinn ATB I recently picked up from Goodwill ($6.99 - for the entire bike).

    That is pretty sophisticated mass-production design, but I've had similar Shimano chainrings that produced a rumbling against the chain that you could feel through your feet.
    They sure shift well though and not all that heavy I have to agree.
