Singlespeed & Fixed Gear - dura ace/sugino compliance

i'm looking for a bb thats going to give me a good chainline with my sugino 75 cranks. i know i could just get the sugino, but i got my eye on a nos dura ace ax bb with a length of 107. is this going to work out?

If I remember correctly, the Sug75s take a 109mm symmetrical

get the super lap at 109.

dont get sealed cartridge.

Since you are in Europe, why not order the Shimano Dura Ace BB-7610 from a local supplier or from Swinnerton (http://www.bikefilth.com/ProductDetails/mcs/productID/762/groupID/4/categoryID/127/v/,).

"Silky smooth precision bearings ensure that all pedal effort is transferred to the back wheel
Square tapered axles to complement Dura Ace 7600 track crankset
Sealed cartridge design for easy installation and replacement
British type - Italian also available
109 mm axle length
68 mm shell width"


dont get sealed cartridge.

Why not?

well all you folks gove me a hard time when i wanted a shimano bb for my sugino 75 cranks....i got the sugino 75 bb in the end...and im completely happy with it

many people have had very good luck putting sugino 75 cranks on 107mm shimano UN-series bottom brackets. i would not hesitate to pick up the bottom bracket that you're talking about. it shouldn't behave much differently. i've been eyeing it, too.

I'm assuming English thread? You have tons of options. Italian? Hell no.

i want cup n ball anyways ...but, why not?

yeah, that would be an option too, but i was going for something with a cheaper price.

so here's a pic of the bb.

...but, if i was to get this bb and the chainline was off by 2mm, couldn't i just make up the difference by spacing my hub accordingly and recentering the wheel?

go for it, chainline will be off by 1mm, not 2mm. not really a big deal.

oh yeah, 1mm ...but is respaceing of the hub something that one would do to compensate?

Because they work too well.

Because they work too well.
yeah, this topic has probably been beaten like a dead horse ...but, i haven't really noticed a great increase in performance from any sealed bb bearings. my old campy bb is silky smooth and it doesn't seem like that will be changing anytime soon. i also enjoy the simplicity of cup and ball, this is a fixed gear forum and fixed is one of the oldest and simplest form of a bike...

Chainline is not only determined by crank and bottom bracket, but also by hub + cog. Even if you get the 109 sugino bb to match the cranks your chainline can still be off because your hub + cog don't add up to the same number. I run a Phil Wood 108 bb with Sugino 75. Phil bbs can be adjusted left right by about 5mm so as long as you have the right ballpark spindle length you can get the PERFECT chainline. Shimano UN bbs can be adjusted too, but only to the right by addind spacers to the fixed cup side. Not sure about the Sugino. Measure your hub + cog chainline and base your bb purchase on that.

thanks 46x17. i've actually never measured my hub+cog or bb+crank. i've just always eyeballed it and never had any problems ...do a few mm in difference really make that much of a difference?

If the chainline is off by a couple of millimeters it's really not a big deal, maybe just a bit noisy. That said, mine was off one mm, so I respaced the axle and dished the wheel ever so slightly so now the chainline is perfect.
