How is a Sugino 75 BB categorized? I need tools to work on it.

I am not sure if I am using the correct terminology but how is a Sugino 75 bottom bracket categorized. I want to pick up some tools to work on my BB (adjusting, installation, and just to learn). I see all these names like: Shimano, ISIS, splined, 20 tooth, 16-notch, external bearing, ISS Drive, ISIS Overdrive, 8-notch.

So which of these apply to the Sugnio 75?

Thanks.

None of the above.

Good old timey square taper. Conflict between whether it is ISO or JIS, but that won't affect the tools in any case.

Sugino has two track bottom bracket models. The top picture shows the standard Sugino 75 version. It is available only in English threading and is Keirin certified (NJS). The "Superlap" model in the photo below differs from the standard version by adding mirror-polishing to the races on both spindle and ball cups (a finish that even Campagnolo hasn't offered in many years).

Both versions have spindles are 109 mm. long with symmetrical overhangs, and either of these bottom brackets will match properly with Sugino 75 track or premium Grand Mighty cranks.

Like Sugino's two track cranks, these units are too often overlooked and underrated in a component market long dominated by Campagnolo and Shimano. I encourage you to give them serious consideration as alternatives to designs of dubious virtue (for track) such as the sealed bearing units now found in current Record and Dura-Ace track models or Shimano's controversial splined crank attachment.

Old fashioned (hook-shaped) lockring tool and a pin spanner. I don't know if you can find the cool tools that have a lockring tool on one end and that skinny box wrench thing on the other side for the fixed cup, but a regular adjustable wrench will do the trick.

On the subject, though, given that you don't know too much about bottom brackets, are you sure you want to be installing one that nice by yourself? Don't those things cost like $100? It's always a good time to learn, but, you know, well...anyway, have somebody with you or read up extensively.

Hi,

DasProfezzional - Thanks for the info. I don't plan on installing it. It's already on my bike (installed by a bike shop). I just want to have the right tools in case I want to adjust it (is this possible?) or clean it.

So which items here would I want? HCW-5 and one of the pin spanners (what color)?

vpiuva - I believe most places list it as ISO. What tools do you recommend?

I have an HCW-4 in addition to the HCW-5, but it doesn't fit every BB. It does fit a French threaded Sugino cup I have, so probably fits yours? I'm not sure which color regular spanner.

Well I thought it was the green one (SPA-1) so I bought it and opened the package. I just tried it and nope, way too big. The hole spacing is much too close (opposite holes).

Edit: Yes it's squeezable. I forgot about that so I'll try that. OK green fits perfectly.

Which bottom bracket tool would I need to use? For example...
