Sorry it's like a year later, but I just picked them up on ebay.

No, but I haven't yet taken apart my cranks. When my BB goes, I'll probably replace it with the White Industries BB they have at Ben's. It's expensive, but it's supposed to be incredibly easy to overhaul. Just pop the old cartridges out, pop the new ones in. I don't have the patience to deal with cup-and-cone with Toronto's weather.

Anyway, here's what Sheldon has to say about it:

Taper matching was fairly important back in the day of loose-ball cup-and-cone bottom brackets, because these required regular maintenance/overhauls, and this required removal of the cranks. Every time you remove and re-install a square taper crank, the hole in the crank is liable to get very slightly larger.

...

These days, however, most folks are using sealed cartridge bearing bottom brackets. With these, there is no routine maintenance required, so typically the crank will be installed once, and will stay in place unless/until the bottom bracket needs to be replaced. This greatly reduces problems of wear to the interface.

I generally avoid mixing sizes on customers' bikes, but I have a lot of experience mixing ISO/J.I.S. in both directions on my own personal bikes, and it as never given me a lick of trouble.

i have the same crank/bb setup and was just wondering if it was going to do any damage
thanks

It's amazing how ignorant some people are of foreign labour.

Thanks! The tires are Continental GP4000.

Any suggestions? I was thinking of a pair of Time ATACs because it seems NOBODY has anything bad to say about those, but I really don't want something that modern-looking.
