Sutherland's 5 Edition devoted 3 pages to "MAXI-TYPE COTTERLESS AXLES".

I think this is what Richard Cielec is referring to.

What the book fails to mention was these "recommendations" were intended as quick and dirty bike shop fixes for hard to find BB axle replacements.

Sutherland's lists both nutted and bolt-on versions on these axles made by Sugino, SR and Shimano.

Most if not all of the "Maxi-Type" axles listed were made of cheap low quality case hardened steel. The hardened layer or "case" was sometimes less than 0.010" thick (0.25mm). Once the thin case hardened layer was worn through the rest of the bearing surface broke down fast.

These types of BB axles were mostly used on lower end Japanese "melt forged" cranksets (melt forged meaning pressure cast)of the 70s and 80s. The stamped aluminum large chainring or web was swagged onto the right crank arm.

>> The Galli spindle is 1118 +2. So, I thought just the ticket for the TA three-arm crank. But the Galli taper is too small of diameter to adequately seat the TA crank (does not work). The Galli taper is 16.45 which as per Sutherlands is Japanese Maxi-type. I do not know what Maxi-type.
>> As per Sutherlands, measured at base of bearing race.
>> 16.45 = Japanese Maxi-type
>> 16.75 = TA and Stronglight (Is this also the JIS spec?)
>> 16.90 = Campag and some others
>> So, the Sutherlands specs indicate that the Galli spindle is not intended for TA nor Stronglight.
>> Sooo...I still don't know what the Galli/Maxi-type spindle is for and I still don't have a spindle for the TA three-arm.

> Richard, Others will undoubtedly tell you that the "Maxy" (or Maxi) was a swaged, alloy cotterless crank made by Sugino (but there was also a similar model made by SR) that used a steel spindle with male threads on the ends and nuts, rather than the more typical female threads and bolts.
> Back to your Galli: I wonder if the "S" symbol you mention is the Ofmega logo, which looks like a sideways S with unequal loops? If so, it would tell us who made the spindles for Galli, and would also explain the Sheldon Brown contention that there are Ofmega spindles with an odd-ball taper (which I have never yet encountered, all the Ofmegas I ever serviced were standard Campy-clones)
