Sugino 75 - quick question please

hi folks.

had a search but couldn't find the answer.

simple question, what bottom bracket thread should i use with a sugino 75.. i'm sure its italian (iso) one?
i'm looking to get a campagnalo centaur bottom bracket, but my mind has cross eyed itself and can't remember if its the british or italian i need?

thanks in advance and apologies for the dumb question.

yep campy. search transmission database

cheers fred.
but it doesnt say if its italian or british.. its italian, i'm sure of it? .. just need clarification before i pull my itchy trigger finger.

British or Italian refers to the BB shell threading not the taper of the BB. Centaur comes in both flavours.

what frame is it for?

dolan track pursuit.
which i am putting a sugino 75 on, i've been recommended to get the centaur (but not sure which one on the following link). i know its 111mm.

cheers guys

111mm BSA version and get it from Condor probably for a tenner less. As they build Campag equipped bikes they get OEM (no retail packaging etc) stock cheaper.

Mine were less than £30 and I have them with SG75 cranks on track and commute bike. Bombproof combo.

ok.. i've confused myself.

i get what you mean doubletap... so the bb comes in italian/british to fit whatever frame as opposed to the crank set?
if thats the case, which one do i need for the dolan, i'm sure i was told italian.. based on me using the sugino 75.

many thanks dude.
i'll pay them a visit on monday.
really appreciate the tips.

I think you/they might be getting taper and threading mixed. ISO taper possibly gets referred to as Italian because Campy use it (as do Phil Wood who spec all their stuff to Italian/ISO standards even down to lockrings) and Sugino 75 happen to be the exception to the Japanese kit = JIS taper I think.

BB threading is independant of that and unless you are buying a made in Italy by genuine Italians frame you would be very unlikely to come across a frame needing an Italian threaded BB.

A standard English bb shell measures 68 mm across, whilst an Italian one is 70 mm. That's the quickest way to check. I'd imagine the Dolan is English threaded but best to check this before you order.

Campag 111mm will give a chainline in the region of 44mm.

Fine if you're running Goldtecs, not so clever else as reference to the Tranny Database will attest.

Spindle requirement is stated as 109mm ISO (Campag, Italian).

In my experience it's a little less on the Mickey 107mm. This BB is adjustable but I found it didn't need a great deal of movement towards the driveside. Sprocket shoulder depth will have an effect, ask Sheldon.

There's a Phil BB to suit, too. 110.5mm, but remember its adjustable. Which the Campag ain't.

A Dey-Do-Doh-Don't-Dey-Doh-Dolan is almost certainly English threaded.

Campag Record Pista will give better chainline, but with a small penalty in non-drive crank offset.

Bear in mind that BB shell width has no influence over spindle length, although it can make life difficult if your cranks have a narrow Q.

BTW, when it comes to 75s there are no quick questions.... ;-)

im confused..

why does need an italian threaded bb to run 75's? has nothing to do with the tapper

or

do you get italian and british types of axle? i.e an italian square tapper bb is has a smalled axle than a british or vice vera.

im getting some 75's hopefully and have a british threaded frame. will i be able to get a bottom bracket to fit my frame and the cranks?

I get vernier measured 42mm centre of frame to centre of chainring on my BJ and nice quiet drivetrains with both Phil Wood and Dura Ace track hubs running Condor cogs.

You'll be reet max.

There's ISO and JIS tapers, and Italian and English threads generally.

ISO = campagnolo generally, and Suginos in this case
JIS = Shimano

You can get both kinds of threading with both kinds of spindle. You'll be looking for a campag BB unless you want to shell out mega bucks for the Phil.

Taper for 75s is ISO, also described as Campag or Italian.

BB threading has nothing at all to do with cranks, it is dependent on frame only.

You can get a BB for an English threaded frame and the 75 crankset.

Check the Tranny DB, it's all there!

The CONdor CNC cog has a shoulder about 1.5mm less than the EAI or Dura-Ace.
It's a useful chainline adjusting tool if the EAI is too wide, or vice versa.

Which, in this case, appears to be a contradiction but obviously works.

This is one of the functions of the Tranny DB, simply to record combos that work.

The Mickey BB is also an affordable ISO taper BB in the right spindle-length range.

you got a link for that tranny db?

It's sticky'd in Mechanics and Fixin.

i'm well confused,
i thought i had it figured out too!!

simply speaking, i have a new build profile hub sitting on a deep v with phil wood cog - ideally i want a sugino 75 to run it off from, so i take it on my dolan being a british frame - i should order the british (bsa) 111mm?

chainline confuses me.. from what i've read/been told.. its ok to be a few mm off?

Yeah mate - that'll give you a slightly wider than normal chainline at the front (around 44mm). But the profile hubs are designed with a 44mm chainline anyway, so it should be bang on

sweet jammy.

again guys i really appreciate the help.
i wish i found this site a month earlier, i could have saved myself so much time/money/stress etc etc.

but you live and learn.

Some of y'all have already received PMs from me (especially Kowalski - sorry!) but I just wanted to make sure I was choosing the right bottom bracket spindle length once and for all. That way I get peace of mind and others out there with the same dilemma get this issue to look back on/search for.

So, I've got Royce track hubs that I want to build up. I'm not sure what chainline they give exactly but I'm gonna guess it's 43mm and not the Goldtec 45mm. I want to use Sugino 75 cranks but I can't figure out what spindle length to go for regarding bottom brackets.

I've pretty much made up my mind and would like a Phil bottom bracket but I've been told by some peeps to go for the 108mm and others to go for the 110.5mm version. I've looked in the transmissions database and, although incredibly helpful, I just can't work it out. The database tells me:

Sugino 75 + Miche + Royce + EAI = kowalski
Sugino 75 + Phil (110.5) + Phil + EAI Superstar = Object
Sugino 75 + Phil (110.5) + Goldtech + Phil Wood = Dancing James
Sugino 75 + Campag Centaur 111mm + Phil Wood + Phil Wood= adoubletap
Sugino 75 + Campag Centaur 111mm + goldtec + eai = dogsballs
Sugino 75 + Sugino 75 + Phil Wood + EAI = mr_tom

So...

Kowalski's using a Miche which is 107mm so I'm thinking a 108mm Phil should work but then Object's using a 110.5mm Phil with a Phil hub (I'm presuming Royce's chainline is similar to Phil's). mr_tom's using a Sugino 75 (109mm) with a Phil hub but then adoubletap is using a 111mm Campag Centaur. The Goldtec combos aren't relevant, I know, but I included them to highlight why I'm so confused. Unless Phil hubs and Goldtec hubs do actually have the same chainlines....do they??

Is it safe to assume that if the hubs have a 43mm chainline to go for the 108 Phil and if it's Goldtec to go for the 110.5? Or should I go for the 110.5 regardless? They're both adjustable so does it even matter?

I can't believe I'm getting so fncking confused about chainlines!

Thanks,

Mike.
