    There are two versions of some of Suntour's ratcheting stem shifters. The ones with the lever pivot axis located [I]in front[I] of the stem quill get my vote, for better clearance with one's knees...

    I like CliffordK's idea of clamping the hole with a bolt/nut, and I like mechanicmatt's idea of "forging" it flat using the jaws of a vise.

    If one could combine these two ideas, I think we have a...

    Quite the tight fit of those calipers around the fat tires. Good job getting the brackets sufficiently precise!

    Do you recall how those Shimano bar-end shifters worked?

    Were they like a...

    How does one distinguish Delta cleats and pedals from ARC cleats and pedals?

    Is it just a matter of red vs. black?

    I myself use SPD-SL pedals and cleats for their secure walking stance and...

    There isn't any particular value in this original paint in this condition in my opinion.

    If this was considerably older and rarer I might not think this, but it's not like this bike in this...

    If there is wobble felt at the pedal, the crankarm would seem to be the more likely culprit than the bb spindle, at least from my experience.

    I've straightened many crankarms in-place using an 18"...

    This is turning out to be a great resto-mod project for sure, and how cool to be starting with a 1960's American Schwinn.

    Take your time. I'm subscribed and enjoying every minute of the suspense.

    Hi Ed, since some of us do hard riding on these 1973 models that you've referred to, perhaps you could enlighten us as to what sort of test that your employer thought to be prudent insurance against...

    The 130mm version appears to have a longer "cone" on the non-drive side, but both 126 and 130mm versions are said to be 7s compatible on the driveside.

    Can the shorter "cone" be sourced to turn a...

    I had sold a Palo Alto bike to one of the (I assume still-current) principals at Palo Alto Bike Shop, and at first wondered if he had perhaps passed it on.

    Anyway, it was a very nice BMZ...

    The stub lengths as you say must be short enough to allow room for the compressed springs between the ends of the axles and the clamping face recesses at each end of the quick release.

    You're right, it still takes some repetition to fully free up the pawl. Some assemblies have more end-play than others, so effectiveness varies when sliding the pawl along it's pivot pin.

    Before gugie fessed up, I figured it was just that Raleigh had dropouts made to the same specifications by the two different vendors, so never bothered to keep them separate.

    Looking closer, it...

    What I believe happened is that the left crankarm simply slid inward slightly along the spindle as the cotter was fitted.

    Before the cotter gets forced in, there is freeplay in both directions,...

    I've seen various brands of shifters slip, either when a layer of protective tape was used, when the paint was new (slippery and/or still yielding), or when the nut just never got sufficiently...

    26.2mm is usually gaspipe, but my Raleigh Super Course with plain-gage 531 frame measures at 26.4mm, so possibly your frame is Cr-Mo.

    Man, is that ever true!

    And come to think of it, there is supposed to be at least that toothy washer in there, usually it's enough.

    Are the clamping bands stamped Campagnolo?

    Are the lever bodies perhaps cracked? I've seen this on a few occasions.

    Odd, this sounds so much like the issue that arises with 7/8" steel...

    The unitized wheel is essentially...
