dcg said:I have an older (80's?) Guerciotti which originally had a Shimano 26 X
24 T bottom bracket and a really strange crankset, I think it was a
Dura Ace. The pedal bolt that the crankset accepted was very large -
about an inch or larger. Since I couldn't use this crankset with
modern pedals, I replaced the bottom bracket and crankset with Campy.
You're describing the Dura-Ace AX series crank which used a 109 mm.
symmetrical spindle (for Italian threaded [36x24] bottom bracket
shells) with a JIS taper.
Quoted message said:I gave the crankset away and kept the bottom bracket.
Now, I have found an older Italian Pinarello (80's?) frame for which I
have no bottom bracket or crankset. It appears that the bottom
bracket will fit just fine.
Does anyone know which older cranksets (that stand a chance of being
available on eBay or loosescrews, etc...) will fit this bottom
bracket?
Symmetrical 109 mm. spindles with JIS tapers have been used in a
number of Japanese track cranks (Shimano 7500 and 7600 models, Sugino
75 and Grand Mighty), but offhand I can't think of another road model
that employed this exact configuration. Campagnolo Victory and Record
C cranks used a 109 symmetrical spindle, but differences in the taper
type (Campagnolo = IS0) may or may not engender chainline issues.
Quoted message said:Would I be better off getting a whole crank & bottom bracket?
Yes. It's almost always best to use the crank and bottom bracket
models that were designed to pair with one another.
Quoted message said:If so,
which one(s)?
There are scores of good cranks from respected manufacturers like
Campagnolo, Shimano and Sugino. Pick one that fits your budget and
fancy.

Thanks for your help. This newsgroup is great!
Ain't it though.
