Wondering if anyone has experience with removing a Sugino 75 BB? I am upgrading my drivetrain and the BB has got to go.

So far I have removed the lockring but I am unsure as what to do next, tools, etc.

umm, what are you upgrading TO? phil wood titanium or something?

(you're gonna need a pin spanner, and maybe a fixed-cup wrench, but more likely a specialized tool usually called a fixed-cup remover)

Yup, a Phil Wood...the tax man or rather shrewd accounting has done me well this year.

nice!
check out sheldonbrown.com for more detailed instructions on how to pull your bb.

use a pin spanner if you have one (which i gather you don't) or something that will fit into the little dimples. a screwdriver will usually work if you have a properly greased, not destroyed bottom bracket shell. turn it the same way you turned the lockring. on the other side you'll need either a 32 or 36mm wrench, or a large crescent wrench.

in a pinch a bent coathanger works as a pin spanner

thanks for the tips! I am trying to build up the tool collection so now I know what to get.

I always wanted an excuse to buy a giant adjustable wrench and the right side of this BB justifies it.

coworkers and I have a running contest for best ground scores. I'm still in the lead with a 2' crescent wrench. I've used it to remove the most stuck fixed cups with ease. Great on freewheels, too.

how do you keep that puppy from slipping off/rounding the flats of the fixed cup?

i've got a honking wrench like that too, but it tends to slip off, leading to bad words, bleeding knuckles, and extra beers.

Last time I used it I came upon a new method to prevent such problems. I used to take out all of the bb parts and save the fixed cup for last. Then I realized that there was a lovely threaded hole in the middle of the spindle. I removed the cranks from the bike, loosened up the other side of the bb, turned the bike over, placed the wrench on the fixed cup, placed a few huge washers around the spindle, and tightened down on the washers with a crankarm bolt. Piece of cake after that. Once it moves a little you have to loosen the bolt some, but then again, once it's moved a little you're home free.

Before I found the wrench my method was to carefully put the fixed cup flats in a bench vise and use the entire frame as a wrench. That leads to all sorts of other chipping and scratching and cussing issues, though. Also, you'd better be damned sure which direction is tight and which is loose if you don't want to destroy some threads.

I've got to get a bigger wrench - I had no idea there was a way to justify the extra beers!

I love whenever my LBS has to weld an old spindle to a stuck cup to get it out.
That beautiful technique has been used on 2 of my old bikes.

is this french or english threaded? if its french, once ya pop her out i might take it off your hands or something... to bad its probobly not french.

and if it is english, I would take care of the disposal for you....

Does anyone know what size pin spanner I need for the Sugino 75 BB? Is it Red (2.2mm) or Green (2.9mm)?

for fixed cups I use big channel locks and a grease rag
and for the non fixed pin kind I use bent needle nose pliers

The sheldon brown fixed cup tool works pretty well and under $5.

i would definitely not recommend the crescent wrench route. it may work but it'll absolutely **** your right cup.

The green, spa-1 pin spanner works on a sugino 75 bb. Just broke down, cleaned and regreased mine the other day.
