Bottom Bracket Problem

Cheers, will check it out.

I'm having a hard time figuring this out, to me it's be like what came first, the chicken or the egg, i don't have my rear built up yet, so how do i know what width BB to get, if i do get the wheel built up then the chances are it will need redishing when i get the BB and cranks, or am i missing something, am i thick.

If it'll fit (shell depth), you need an english cupped miche primato.

If the cups are too long, you need something around a 107/109/111mm threadless, depending on what your rear spacing is (120 / 126 / 130). Or a dremel to reduce the depth of the cups.

When you mention spacing, this is the problem, i don't know where to start as my rear wheel is not built up yet, sooo how can i decide on a BB with no rear wheel and how can i set the rear wheel up with no BB or cranks or am i missing something.

Would these cranks fit on a Miche spindle

looking on the transmission thread people use Sugino-75 cranks with a Miche BB but the ones on ebay don't say what model the Sugino cranks are. HEEEEELLLLLP

yes they do, it says they are the RD model.

you need your rear hub, that will tell us what the chain line is, then you need cranks, then a BB that go together to match the chain line given by your hub/ frame combo. so you should build your wheels first if you are un-sure what your chain line will be.

now what kind of hub are you using? if it is a track/ ss freewheel then it will most likely be a 45mm chain line, then any combination of track cranks and the BB that fits them should suit. my sugino RD messengers (different to the ones in your link) needed a 103mm JIS bb to match the 45mm chainline of my phil wood hubs, i went with a phil wood 103mm jis bb, but the sugino 103 jis bb would have had the same effect on my chain.

spacing refers to the distance between the drop outs on your frame, they should be around 120-130mm. I think you are making this more complex then it needs to be. chain line seems like a dark art at first, but after you set up two or three bikes it starts to work out.

Well this particular bike is being set up with a sturmey archer 3 speed,reason, i will be using the 3 speed till i'm a little fitter and will be passed on to my missus (she's not wanting a SS/Fixed) i have another frame that i will be building up in the near future as a SS, at present i'm using this bike as a learning curve, does this change things.

measure the gap between the rear dropouts, it's hard for us to help without all the info, as you're finding out!

On my crappy calipers i,m getting 123.7 mm the paint is scraped off in parts of the inner faces of the dropouts and that's as accurate reading as i can get.

next question, how far does the thread go in the BB shell?

16.5 mm

The threads stop at 16.5mm there is a small unthreaded section then you come to that lip (pictured) up to the lip is 20mm

ok, 20mm. anyone got a set of miche cups and a ruler handy?

C'mon lads/lasses get your miche's out.

God you are having a time of it! Your first build is all a bit daunting. Think I got off lightly reading this. Just got a 110mm italian bb, screwed it in, banged on my old cranks and big chain ring, got a 120 oln rear wheel and I was away, great chainline. Sorry I know that doesnt help, shut up me. Good luck with your build Boss.

shut up me.

Yeah shut up you, lol. but yes it is turning into a bit of a mission, i'll plod on though, dont know where i'm going to plod to though as i don't seem to be getting any further on.

You should have a chat with Whatamidoing, he did a peugeot build recently, have seen it and it all looked and worked ok.

Ok will do, i'll have a search for some of his threads first, having said that it wasn't a purple one was it, if so i think i've seen it.

Black as I remember it, with white stripes.
