Just in case the info is of use to anyone hereabouts...

If you want a cartridge BB for a Sugino 75, don't believe the information on just about every website which tells you any JIS (ie ShimaNO) BB will fit.

It's an ISO taper so the Campag ones are an obvious choice.

I was a bit doubtful when the Dolan dude told me this, but Sheldon agrees and now I've got the instruction sheet in me grubby paws I can confirm it.

I tried putting my sug75s on a campy bb - didn't accept. This is a pic of my jis phil on sug 75 crankset, and it fits well.

i don't think it's as clear cut..

Yeah, this is one of the great confusions out there. Everyone (inc major manufactures - KHS for example) ran them on JIS. But now the Sugino website clearly states that they're ISO but folks are still saying that it worked best with JIS/ISO (delete as appropriate).

Wish there was some clarity here, until then I'm sticking with the Sugino 75 BBs.

speaking of something similar, any one know the type and size on the ....ah, hum, langster.....mines creaking like fuck and will have to replace it.

err...snap!

Hubjub sell this with the RD messenger, but not sure if they sell it seperately:
A little extra gets you one of Sugino's own 103mm square-taper BBs plus crankbolts, enabling you to dial in your chainline for an industry-standard 42mm (ish) hub

I've been having real trouble getting the Sugino 75 loose-bearing BB dialled-in. Does anyone know if there's a knack to it that I'm missing. (Fit the drive-side cup. Grease a set of bearings, drop those in. Add the spindle and the plastic thingy. More heavily-greased bearings, then the adjustable cup. Tighten until too tight, then back off until running smoothly. Apply lockring.)

I find that either I get rattling/grinding or clicking. The only useful advice I've had so far is to have the BB shell re-faced. Any other top tips?

Are you missing something from the mix? Spacer perhaps? Right number of bearings each side? BB shell isn't too wide is it?

Just about the only thing that fits together on Project Dolan is the 75 on the Campag BB.

The Mirage BB only costs ten sheets.

Theres no trick, AFAIK, to Sugino 75 BBs. They work just like any other loose ball adjustable BB.

I assume you're using a pin spanner and right tools, have the bearings facing the right way (assuming this is a new 75 BB with the caged bearings) and know what yer doing, so my only thought is maybe you're using too much grease and getting false positives when trying to get the adjustment right.

Aside from that, I'd inspect the bearings and races for damage; try with loose ball bearings as maybe the retainers are damaged in some way?!?

I know how frustrating it can be when stuff just doesn't work.

Yeah - I'm doing it by the book. Might give the loose bearings a crack, although that sounds like inviting even more grief! Possibly too much grease - where would you draw the line between 'too much' and 'not enough'?

It looks OK, and the lockring fits on nicely, so I don't think it's because the shell is too large. And the bearings are caged and came with.

If you can be arsed about putting ISO on JIS and have OCD, read this thread http://www.bikeforums.net/showthread.php?t=290531 it gets " ranty" and even references Sheldon (RIP) http://www.sheldonbrown.com/bbtaper.html
