Can't get a 83mm bb for sunday will 68 or 73 work?

[xemini]

I guess fsa doesn't make the 83mm or something will 68or73 work?

[spitfireeye-xvi]

no, this will not work, the shell for the bb is 83mm wide, meaning that if you tried to put a 68 or 73 on it would be much to short, do you have to get an fsa, pick up a raceface one or something to do your job.

[ZHendo]

if it says that the bb is a 83mm, then that is the only one that will work. fsa does make them for the gap megaexo cranks, unless you are talking isis.

[sbstianfreeride]

I think that it wouldnt matter. Because the BB plastic insinde part will just be sitting there without touching the other barings. Might get dirty though.
Or does it matter?

[jvnixon]

It won't work and it does matter. You need 83mm cranks & bb (the 68/73mm spindle isn't long enough).

[xemini]

what do you guys recommend for a good durable bottom bracket for my sunday then? that is 83mm?

[jvnixon]

What cranks do you have? FSA makes a nice 83mm ISIS DH bottom bracket if you have ISIS.

[tsamps]

I just got an 83mm FSA bb for a sunday. Go to you local bike shop and see if they can order from quality or bti (i think its bti, or somethin like that). The platinum dh bb that fsa makes comes in that size, in an isis, thats your option.

[xemini]

i have the fsa gap crankset

[bizutch]

Shimano Saint or Race Face Diabolus 83mm Crank/BB all in 1
...just get the whole setup and be done with it.

[blue]

FSA will be making Gravity Lights for 2008 in MegaExo. They currently make the Gaps and Gravitys in MegaExo 83mm.

[frznnomad]

ummm no. everbody and there mother makes a 83mm bb and they also make the internal bearing and crank combos. for fsa you have the gravity and the gap crank set. then you have all the raceface line, shimano saint and hone, and then i think truvative makes them too im just not 100% on which model. so there out there man you just got to dig for them sometimes.

but with Truvativ's you get a lame 53mm chainline instead of 56.

[Transcend]

The stuff funn sent me is pretty damn nice. I am not running the 83mm BB, but it is the same thing as the 68/73 i have.

*backs out of pinkbike-ish thread*

:shocked:

[rcdreamer]

Cambria bike has the fsa platinum DH Bottom bracket in 83mm ISIS!
Just go to the site and search 83mm and it will bring it up.

[xemini]

-quote from the bike shop (with that bottom bracket, the only thing that differentiates between a 73 and an 83mm is the sleeve, which i will reuse) (thread depth on the cups is identical) (i contacted FSA to make sure)

this is what the bike shop told me so i guess 73 mm will work on an 83mm bottom bracket for a sunday... can anyone confirm this?

[Dogboy]

That is typically all that differentiates a 68/73mm BB, but it seems unlikely that an 83mm BB would only use a different cup. It sounds like the shop has assured you that it will work, so have them install the BB and if it doesn't work they can eat the labor cost and get you the correct BB.

[rcdreamer]

Typically the spindle width is different too. Meaning the crank arms sit farther apart to clear the frame.

time to look for a new shop

[xemini]

so i 73mm wont work then? i emailed them and said not to order it a week ago then they tell me todays its in and that it will work.. im not sure what to do, its gonna cost 117$ cnd plus service probably and its not even the correct 83mm for an ironhorse sunday.. what should i do can someone confirm for sure if this will work or not

IT WILL NOT WORK... YOUR FRAME REQUIRES AN 83MM BOTTOM BRACKET SHELL, NOT A 68, NOT A 73... 83MM ONLY!

[Dogboy]

How about a 100mm? :busted:

[spitfireeye-xvi]

ok heres the deal, for an outboard bottom bracket they use this little sleeve in the middle, its for keeping junk out of your frame, that is what makes up that spaceing difference, you CAN reuse the sleeve but its not recommended, the threads would be the same, and you could use the cups, but make sure you get the right sleeve, race face will even sell you a conversion kit for like 10 bucks for there x-type bottom brackets, but you have to have the right spindle length for your cranks other wise your SOL!

[RaID]

The actual BB cups for 73mm BB will work on your 83mm BB

HOWEVER the FSA Gap cranks DONT come in a 83mm BB compatible spindle.
YOUR CRANKS WILL NOT WORK ON A 83mm BB SUNDAY

[fellow pinner]

just get something light, you dont need a dh bb, some Ti if you have some cash. i run a Ti truvatic external bb for dh...works fine

[davep]

Ding Ding Ding.....We have a winner!!!!

[Udi]

FSA Gap's do exist in 83mm, they're a really nice crankset for 07 and come on the 07 Sunday Team. Not sure if you can buy them aftermarket (in 83mm) from FSA though.

But yeah, like everyone has said a million times - you need an 83mm crankset for a sunday, 68/73mm sets won't work. Nice to see it's sinking in for this guy eh...

[funkendrenchman]

Am I the only one that thinks he should get the 73mm?:lighten:

[scottishmark]

shave 11mm off the shell? ;) :rockout:

the fsa website says they dont make 83mm BB version, i guess they could be OEM

[Udi]

fsa website is always out of date.. not the source to use

[Patan-DH]

I got the isis FSA platinum DH 128/83mm
6 or 7 races since....so far so good. just bent a couple of hussefelts cranks after hitting a rock and the spindle smooth as ever and straight.

I seen that truvativ also makes (ore used to) a gipapipe DH in that size. With 4 bearings instead of 2 like the FSA.
First I was thinking of getting the gigapipe but it came that was WAY more expensive than the FSA one.

Talking about this FSA 83mm bb.
¿How durable is it? ¿anyone have broken one yet?

And i wonder if when it gets worn out you can replace the bearings with universal ones.......or are these specific for the bb?

[xemini]

well i have the FSA gap cranks that came stock on my 06 sunday team, and the bottom bracket is getting loose so it needs replacing, so since i have the cranks from it will the 73 mm work by just reusing the sleeve like someone said earlier?

[Udi]

Yes, should work.... get some pics or compare the external BB cups for yourself to make sure.

As long as the cup width L/R are identical (ie they protrude the same distance from the BB shell as the old ones) you're okay. The sleeve should fit, but it isn't critical on the sunday anyway because the BB shell is sealed/closed (there are no holes inside it for water to enter via the frame).

[switch98]

The cups are identical on a bb with a 68/73mm shell, and that of one with an 83mm shell, the only difference is the center piece, which does nothing, FSA themselves said to reuse the sleeve from his old bb, how do I know? because I was beside the other mechainic from our shop when they called, so before you open your mouths and make a dammed fool out of yourself by saying it won;t work, or get a new shop, do some research like we at the shop have already done.

Here's a good question.

Why is this guy even online asking these questions if this shop knows what they're doing. (3 pages long:lighten: )

What shop is this anyway?

No, he just phrased his question/s INCREDIBLY vaguely up until post #34 where he finally mentioned his exact problem and what he was intending to do, to which I replied (in post #35) saying that it's fine.

We aren't mind readers... the answers you get are only going to be as good as you can phrase the question you want to ask. You might be the damned fool here for expecting a response any different from what was recieved, given the vague questions he asked.

[davep]

Excatly..there was NO mention of the fact that the cranks in question were OEM only 83mm cranks with using hollowtech/x-type bb. That is why there are so many varied responses...all correct within the information given by the O.P. As you can see mr shop guy, most thought the cranks were ISIS and the O.P. said nothing to the contrary.

For one, who still uses ISIS bbs in full on dh bikes anymore, those of you who do, your bike is not what it should be, two, he never once said it was ISIS, so those of you whom assumed they were, well we all know what happens when you assume things.

[davep]

I will give you that there is a definate lack of reading comprehension displayed by many of the responders....and bad assumptions made.

But when people at first pointed the O.P. to an 83mm ISIS bb, he/she never came back and said he was looking for bearing cups for an external bb...not really an 83mm bb. It is sort of semantics, but the o.p. does not need a bb (which would NEED to be purchaced in the particular size determined by the frame), he needs bearing cups (or in reality just new bearings as they can be easily replaced).

To make things more vague/confusing..the o.p. said he had gravity gap cranks..something that is only available in 68/73 to the general public. No mention of the fact that they are OEM and cam on the bike..just that he has some cranks (0nly avail in 68/73 and wants to put them on his sunday (83).

Oh by the way, LOTS of people run ISIS on this kind of bike (83mm bb) due the overwhelming lack of lighter weight external bb cranks available for the 83mm bb standard. See here: http://www.ridemonkey.com/forums/showthread.php?t=174579&highlight=lightest+83mm


You would have been much better received if instead of telling everyone who tried to help, "so before you open your mouths and make a dammed fool out of yourself " that you simply stated that they were OEM 83mm external cranks and just needed new cups/bearings..all would have been good..rather than you looking like a d1ck.

I agree that if it was a isis bb or a howitzer bb that it would need to be the correct length.
Maybe if you all were more interested into getting more information instead of lighting the torches and calling out a shop when you have little to no information on the situation.
A very vauge question was asked, and none of you probed for more information, so its not my fault that 90% of you went way into the wrong direction.
If calling me names makes you feel better about the lack of knowledge put forth in this thread feel free, I can handle it, as no matter what you say, I was right and helped solve this guys problem whereas all of you confused him.
